Best Lift Pump For 6 7 Cummins: Compare Eight Options
A strong lift pump for a 6.7 Cummins should match your Ram’s model years and power needs, with a clearly stated flow rate and compatible installation. The FASS Titanium Signature Series models lead this group because they list 6.7 Cummins fitment and distinguish their capacities: 100 GPH supports up to 600 hp, while 250 GPH supports up to 1,200 hp. Several 165 GPH replacement systems also list 2005–2018 Ram 2500 and 3500 fitment, but provide less detail about supported horsepower.
This roundup compares eight options, including models intended for older Cummins engines and a broadly described pump whose listing points to GM applications. Check the exact year, engine, and application before ordering; shared flow figures do not guarantee interchangeability.
The FASS Titanium Signature Series 100GPH is the best overall choice here for a 6.7 Cummins when its listed fitment matches your truck. It covers Ram 5.9L and 6.7L engines from 2005–2018 and 2021, and supports up to 600 hp. Choose the FASS Titanium Signature Series 250GPH instead if your build needs its stated capacity of up to 1,200 hp.
For a replacement-style system with 165 GPH listed, Torchbeam specifies fitment across several 2005–2018 Ram 2500 and 3500 applications.

Detailed Reviews: Best Lift Pump For 6 7 Cummins

#1 · Best Overall
1. FASS Titanium 100GPH
- Compatible with Vehicle Type: Dodge Ram with Cummins 5.9L and 6.7L diesel…
- Operation Mode: Mechanical
- Weight: 28 lb
Best for: Moderate-output FASS system.
Why it ranks #1: Lists 2005–2018 and 2021 Ram 6.7L fitment, removes water, air, and debris, and states support for engines up to 600 hp.
Support for up to 600 horsepower and a 100-gph rating define the FASS Titanium Signature Series TSD07100G as a lower-capacity choice within the listed product range. Its stated fit covers Dodge Ram 5.9- and 6.7-liter Cummins trucks from 2005–2018 and 2021.
The 100-gph rating and up-to-600-hp support give buyers capacity figures to weigh against their engine setup. FASS says the system removes water, air, and debris from diesel fuel and protects the injection system, linking filtration to the pump’s stated purpose. A 0.5-inch inlet and 0.31-inch outlet are specified for connection planning, while the listed 28-pound weight and 18-by-14-by-11-inch dimensions help with installation logistics.
- 100-gph rating
- Supports up to 600 hp
- Removes water, air, and debris from diesel fuel
- 0.5-inch inlet and 0.31-inch outlet specified
- The listed capacity is up to 600 hp, below the TSD07250G’s stated 1,200-hp support.
Skip it if you need stated support above 600 hp; the FASS TSD07250G lists support up to 1,200 hp.
This FASS suits a 2005–2018 or 2021 Dodge Ram Cummins owner whose setup falls within the stated 600-hp support and who wants the listed fuel-cleaning functions. Check the specified connections and capacity against your installation.

#2 · Highest Capacity
2. FASS Titanium 250GPH
- Compatible with Vehicle Type: Truck
- Operation Mode: Mechanical
- Weight: 30 lb
Best for: High-output FASS Cummins system.
Why it ranks #2: Matches listed 2005–2018 and 2021 Ram Cummins fitment and provides the group’s highest stated capacity, supporting up to 1,200 hp.
A 250-gph rating and support for up to 1,200 horsepower put the FASS Titanium Signature Series TSD07250G toward high-output Cummins applications. Its stated fit covers RAM 5.9- and 6.7-liter engines from 2005–2018 and 2021, giving buyers a defined application range to check.
The 250-gph flow rating and stated support up to 1,200 hp give modified-truck owners two concrete capacity figures to consider. FASS also says the system removes water, air, and debris from diesel fuel, a filtration function tied to protecting the injection system. Its 30-pound weight and 18-by-14-by-11.5-inch dimensions are useful for planning handling and installation space; the listed operating mode is mechanical.
- 250-gph flow rating
- Supports applications up to 1,200 hp
- Removes water, air, and debris from diesel fuel
- Listed fit for 5.9- and 6.7-liter RAM Cummins, 2005–2018 and 2021
- At 30 pounds and 18 by 14 by 11.5 inches, it requires planning for handling and installation space.
Skip it if you need a lower-capacity FASS option for up to 600 hp; the FASS TSD07100G is listed for that range.
Choose this FASS for a listed 2005–2018 or 2021 RAM Cummins application that calls for its 250-gph rating and stated 1,200-hp support. Its 30-pound weight and dimensions matter when planning installation.

#3 · Broad Year Coverage
3. Torchbeam 165GPH System
- Compatible with Vehicle Type: Truck
- Operation Mode: Mechanical
Best for: Wide-year Ram replacement system.
Why it ranks #3: Lists 165 GPH replacement-system fitment for 6.7L Ram 2500 and 3500 models from 2007–2018, plus a pressure sensor and strainer.
The listed fitment spans Ram 2500 and 3500 trucks from 2005 through 2018 across specified 5.9- and 6.7-liter Cummins applications. That broad year coverage makes the Torchbeam system a candidate for owners checking a replacement against a detailed model-and-engine list.
Torchbeam names Ram 2500 and 3500 applications, with listed 5.9-liter coverage in selected 2005–2009 and 2005–2007 years and 6.7-liter coverage from 2007 or 2011 through 2018 depending on model. The included pressure sensor, seal ring, and strainer provide specifically listed system components for installation planning. An instruction is also included, while the product is identified as mechanical and rotary-vane style.
- Lists Ram 2500 and 3500 applications
- Fitment details name both 5.9- and 6.7-liter engines
- Includes pressure sensor, seal ring, and strainer
- Instruction included; rotary-vane style listed
- The listing says this product is not sold in California under CARB requirements.
Skip it if you live in California; this Torchbeam listing says it is not sold there under CARB requirements.
This is worth considering for a Ram 2500 or 3500 owner whose year and engine match the detailed fitment list and who values the included sensor, seal ring, and strainer. California buyers are excluded by the listing.

4. Orceed 165GPH System
- Compatible with Vehicle Type: Truck
- Operation Mode: Mechanical
Best for: 2005–2018 Cummins replacement.
Why it ranks #4: Specifies compatibility with 2005–2018 Dodge Ram 2500 and 3500 trucks with 5.9L or 6.7L Cummins engines.
Compatibility with 2005–2018 Dodge Ram 2500 and 3500 trucks equipped with 5.9- or 6.7-liter Cummins engines is the Orceed system’s clearest buying point. Its title identifies a 165-gph diesel lift pump system, pairing a stated flow figure with a specific model-year range.
The listed 2005–2018 Ram 2500/3500 compatibility helps owners narrow the application, and the 5.9- and 6.7-liter engine references cover the Cummins options named by the product. Its 165-gph title rating gives buyers a stated flow figure, while the aluminum body and mechanical operation describe the system’s construction and operating type. The supplied facts identify it as a replacement system but do not detail included installation components.
- 165-gph rating in the title
- Lists 2005–2018 Dodge Ram 2500 and 3500 fitment
- Names 5.9- and 6.7-liter Cummins engines
- Aluminum body with mechanical operation
- The supplied listing does not specify included installation components.
Skip it if you need a listed filter-removal feature; the FASS TSD07100G specifies removal of water, air, and debris.
This Orceed system suits owners of the stated 2005–2018 Ram 2500 or 3500 Cummins applications seeking the listed 165-gph replacement. Its supplied details omit included components, so plan installation around what the listing actually specifies.

5. Flynsu 165GPH Pump
- Compatible with Vehicle Type: Truck
- Operation Mode: Electric
- Weight: 12.51 kg
Best for: 165-GPH Ram replacement.
Why it ranks #5: Its title lists 2005–2018 Ram 2500 and 3500 5.9L and 6.7L Cummins fitment, with 165 GPH capacity.
A listed 165-gph rating makes the Flynsu lift pump a high-flow replacement option for specified 2005–2018 Dodge Ram 2500 and 3500 applications. Its title identifies both 5.9- and 6.7-liter Cummins diesels, giving buyers a broad model-year range to check against their truck.
The 165-gph title specification establishes the pump’s stated flow, while the 2005–2018 Ram 2500/3500 application and 5.9/6.7-liter Cummins designation define its listed vehicle range. Electric operation is specified, which matters when considering the replacement’s operating type. Metal-alloy body material and matching 0.63-inch inlet and outlet connection sizes give buyers concrete construction and connection details to compare with their system before installation.
- 165-gph flow stated in the product title
- Lists Dodge Ram 2500 and 3500 applications
- Names 5.9- and 6.7-liter Cummins engines
- Metal-alloy body with 0.63-inch inlet and outlet connections
- The supplied specifications identify electric operation but provide no included-component or installation details.
Skip it if you want a listed 100-gph system for a 2005–2018 truck; the FASS TSD07100G gives that flow rating.
Consider this Flynsu replacement when your Ram 2500 or 3500 falls within the stated 2005–2018 range and you want its listed 165-gph flow. Confirm the engine and connection details for your particular installation.

#6 · Broad Engine Listing
6. PPE Diesel Lift Pump
- Compatible with Vehicle Type: Truck
- Operation Mode: Automatic
- Weight: 3.8 lb
Best for: Reusable-filter multi-diesel option.
Why it ranks #6: Lists Cummins among compatible diesel engines and up to 160 GPH, but its additional description identifies a 2001–2016 GM application.
A reusable internal fuel filter distinguishes PPE’s lift pump, while its stated compatibility spans Dodge Cummins, GM Duramax, and Ford Powerstroke diesel engines. The listing also specifies up to 160 gallons per hour, making flow and filter service central details for prospective buyers.
The reusable internal filter gives maintenance-minded owners a listed service feature, while the up-to-160-gph rating establishes the stated flow ceiling. PPE says the pump eliminates vacuum from the tank to the high-pressure injection pump, linking its function to fuel delivery. Its 1/2-inch NPT inlet and outlet provide connection specifications for planning, and the listing names biodiesel and low-sulfur diesel compatibility plus 50-state emissions legality.
- Up to 160 gallons per hour
- Reusable internal fuel filter
- 1/2-inch NPT inlet and outlet
- Listed as compatible with biodiesel and low-sulfur diesel
- The supplied application description names 2001–2016 GM, despite broader engine compatibility in the title and features.
Skip it if you need a pump specifically listed for 2005–2018 6.7-liter Ram fitment; the FASS TSD07100G states that application.
Consider PPE if you want the listed reusable-filter feature, up-to-160-gph flow, and compatibility details spanning several diesel makes. The application description specifically names 2001–2016 GM, so Cummins buyers should resolve that fitment ambiguity before purchase.

7. AirDog Raptor Lift Pump
- Compatible with Vehicle Type: Truck
- Operation Mode: Mechanical
- Weight: 7.3 lb
Best for: Block-mounted early Cummins replacement.
Why it ranks #7: The 100 GPH Raptor is specified for 1998.5–2002 Dodge Cummins trucks, not the 6.7L Ram applications listed by higher-ranked options.
Factory-bracket mounting on the side of the engine block is the defining fit detail of AirDog’s 100-gph Raptor pump. It is specified as a factory replacement for 1998.5–2002 Dodge Cummins trucks, giving owners in that application a directly stated mounting location and flow rating.
The 100-gph rating provides a clear flow specification, while the 1998.5–2002 application limits the choice to the listed early Dodge Cummins range. Its description says it mounts to the factory bracket on the engine block, helping buyers understand where the replacement sits in the installation. The pump is listed as mechanical, with a metal body and 0.5-inch outlet connection; the included-components field names only the main component.
- 100-gallon-per-hour flow rate
- Factory replacement application for 1998.5–2002 Dodge Cummins
- Mounts to the factory bracket on the engine block
- Metal body and 0.5-inch outlet connection
- Package contents list only the main component, rather than a broader installation kit.
Skip it if you need a pump for a 2005–2018 6.7-liter Ram; the FASS TSD07100G lists that later application.
This suits a 1998.5–2002 Dodge Cummins owner seeking a 100-gph pump that mounts at the factory engine-block bracket. Its stated model years and main-component-only contents make application and installation planning important.

View on AmazonWhy it ranks #8: Its 95 GPH flow and up to 100 psi suit listed 1994–1998 12-valve Cummins applications, rather than a 6.7 Cummins.
Flow up to 95 gallons per hour at a maximum 4,000 rpm gives Power Driven Diesel’s Hot Rod pump a concrete performance focus for early second-generation Cummins trucks. Its stated application is 1994–1998 12-valve models, with the description covering stock trucks up to 750 horsepower.
The up-to-95-gph flow figure and 100-psi maximum give buyers clear operating specifications when choosing a pump for a modified fuel system. Its stated fit is limited to early second-generation 1994–1998 12-valve Cummins trucks, so it is not a general 6.7-liter replacement. The kit includes gaskets, studs, nuts, and a bowl-delete spacer and/or input adapter, providing listed installation hardware for its intended setup; check which adapter configuration is supplied.
- Flows up to 95 gallons per hour
- Maximum operating speed listed as 4,000 rpm
- Up to 100 psi
- Described for stock trucks up to 750 hp
- Application is limited to early second-generation 1994–1998 12-valve Cummins trucks.
Skip it if you own a 2005–2018 6.7-liter Ram; the FASS TSD07100G lists that application instead.
Choose this for an early second-generation 1994–1998 12-valve Cummins owner seeking a modified pump with listed flow and pressure limits. Its stated application does not cover later 6.7-liter Ram trucks, so verify the generation before choosing.

View on AmazonAvoiding Cummins fitment mix-ups
A Cummins label alone does not establish 6.7L fitment; match the truck’s year, engine, and mounting arrangement to the listing. The AirDog Raptor here is explicitly for 1998.5–2002 Dodge Cummins, and the Power Driven Hot Rod Pump is intended for early second-generation 1994–1998 12-valve trucks. Neither listing establishes compatibility with a 6.7L.
At the other end, the FASS models list Ram 5.9L and 6.7L applications from 2005–2018 and 2021, while Torchbeam gives individual year ranges spanning 2005–The Flynsu title claims 2005–2018 fitment, and Orceed names the same years and engine sizes.
These range descriptions are not proof that every configuration uses the same connections or installation. Verify exact year and truck details against the seller’s fitment information before choosing a pump; the Torchbeam listing specifically advises checking confirmed fitment.
Understand what GPH does—and does not—tell you
A higher GPH figure alone does not establish that a pump is the right match for a particular 6.7 Cummins build. The products span 95 GPH for the older Power Driven pump, 100 GPH for AirDog and one FASS, 160 GPH for PPE, 165 GPH for several replacement systems, and 250 GPH for the other FASS. Only the FASS listings pair a capacity with a stated horsepower ceiling: up to 600 hp for the 100GPH model and 1,200 hp for the 250GPH model.
The other flow figures should not be treated as equivalent horsepower ratings. A lift-pump choice also depends on the application and fuel-system requirements, which these listings do not fully specify.
Use listed fitment first, then compare capacity against your engine setup; seek vehicle-specific guidance if required pressure, plumbing, or supporting changes are unclear.
How to Choose a 6.7 Cummins Lift Pump
Vehicle-year and engine fitment
Start by matching the pump’s stated vehicle years and engine to your truck, rather than relying on the Cummins name alone. FASS lists 5.9L and 6.7L Ram fitment for 2005–2018 and 2021; Torchbeam identifies several 6.7L Ram 2500 and 3500 year ranges from 2007–Orceed and Flynsu list 2005–2018 Ram 2500 and 3500 applications with 5.9L and 6.7L engines.
By contrast, AirDog specifies 1998.5–2002 and Power Driven specifies 1994–1998 12-valve use. Buyers with a clearly matching later-model truck should focus on the listed replacement systems; owners of older trucks should not assume a 6.7L fit.
Flow and stated horsepower capacity
Compare flow figures alongside any horsepower capacity the listing actually provides. The options range from 95 GPH for Power Driven to 250 GPH for FASS, with 100 GPH, 160 GPH, and 165 GPH choices between them. FASS states that its 100GPH model supports up to 600 hp and its 250GPH model up to 1,200 hp.
Those are the only explicit horsepower ceilings in this product set, so do not infer an equivalent rating from another pump’s GPH alone. A buyer whose build fits the stated 600 hp ceiling can consider FASS 100GPH; someone needing the listed higher ceiling can compare FASS 250GPH, while checking vehicle fitment and the rest of the fuel system.
System details and included pieces
Check whether the listing describes a complete system and names useful components, rather than assuming every pump includes the same hardware. Torchbeam lists an instruction sheet, pressure sensor, seal ring, and strainer, while Power Driven says its kit includes gaskets, studs, nuts, and a bowl-delete spacer and/or input adapter. AirDog identifies its included component as the main component only.
The FASS listings provide capacity, application, and fuel-cleaning claims, but the supplied details do not itemize installation hardware. Buyers replacing a system should verify what parts are needed for their truck and what arrives in the box.
If installation pieces matter, the Torchbeam or Power Driven component lists offer more detail, but their stated fitment still needs to match the vehicle.
Which Lift Pump Should I Choose for My 6.7 Cummins?
For a 2005–2018 or 2021 Ram 6.7L that fits its listing and a stated ceiling of up to 600 hp, choose the FASS Titanium 100GPH. If the same listed fitment applies and you need the product’s stated capacity of up to 1,200 hp, choose the FASS Titanium 250GPH. For a 2007–2018 Ram 2500 or 3500 6.7L replacement application, Torchbeam 165GPH System lists a pressure sensor and strainer; Orceed 165GPH System and Flynsu 165GPH Pump also name 2005–2018 6.7L Ram fitment.
PPE Diesel Lift Pump lists Cummins broadly, but its additional description points to GM fitment, so confirm before considering it. AirDog Raptor Lift Pump and Power Driven Hot Rod Pump target older Cummins applications, not the listed 6.7L use case.

Frequently Asked Questions
How can I confirm a lift pump fits my Ram’s exact year and engine configuration?
Match your truck’s year, engine, and Ram model to the product’s stated fitment, then confirm with the manufacturer or seller before ordering. Listings may cover different combinations of 5.9L and 6.7L engines or Ram 2500 and 3500 applications, so a broad Cummins description alone is not enough.
What fuel pressure should a 6.7 Cummins lift pump maintain under load?
Use the pressure specification for your exact engine and fuel-system configuration; the supplied product information does not state a required pressure under load. Check the pump manufacturer’s installation guidance and verify pressure with an appropriate gauge under the conditions specified. Do not assume that a listed flow rating establishes pressure.
Can I install a higher-GPH lift pump without changing other fuel-system components?
Not necessarily. A higher GPH rating alone does not establish compatibility with the rest of your fuel system. Confirm the pump’s application and installation requirements with its manufacturer, including whether other components or changes are needed for your specific truck and build, before selecting a higher-capacity option.
Which listed systems specify fitment for a 2007–2018 Ram 2500 or 3500 6.7L?
The Torchbeam 165GPH system lists that replacement application and names a pressure sensor and strainer. Orceed’s 165GPH system and Flynsu’s 165GPH pump also name 2005–2018 6.7L Ram fitment. Confirm the exact truck configuration against the product listing before choosing.
Should I consider the PPE lift pump for a 6.7 Cummins?
Verify its application before considering it. The product title names Cummins, but its additional description points to GM fitment, so the supplied information does not establish a clear 6.7 Cummins match. Confirm compatibility with the seller or manufacturer for your exact Ram and engine configuration.
Final Words
For a listed-fitment 6.7 Cummins, the FASS Titanium Signature Series 100GPH is the overall choice, with a stated capacity up to 600 hp. Choose the 250GPH version when the build needs its stated capacity up to 1,200 hp. For a replacement-style option, compare the 165GPH systems and verify exact fitment.
Treat the PPE listing cautiously, and avoid older-application pumps for this use case.
