The best LB7 lift pump kit depends on whether you need a complete fuel system, a pump-only upgrade, or replacement filters. The AirDog 150 GPH system is a strong match for buyers who want an LB7-listed kit with frame-mounted installation and no drilling. The FASS Titanium system suits shoppers prioritizing water, air, and debris removal, while the PPE pump is a higher-flow option with a reusable internal filter. Confirm exact year, engine, and included components before ordering.

| 1R-0750 Fuel Filter Kit | Filter replacement or maintenance | Two filter sets |
AirDog 150 GPH LB7 Lift Pump
Best for: LB7 owners seeking a lift pump system with listed, no-drilling frame mounting. The product names LB7 alongside LLY, LBZ, and LMM engines in 2001–2010 Chevrolet and GM Duramax applications. Its single-piece pump body is preset at 8 psi, according to the listing.
The listed features say the unit removes air and vapor from diesel fuel and mounts directly to the frame. The product description also claims potential improvements to throttle response, torque, engine performance, fuel economy, injector life, fuel flow, and injection pump life; these are seller claims, not guaranteed results.
Limitation: The listing does not provide a detailed included-parts inventory here. Verify that the kit and fitment match your truck’s model year and configuration before purchase.
FASS Titanium Signature Series 100 GPH
Best for: Buyers who prioritize fuel cleaning features alongside a lift pump system. The listing identifies a 100 GPH system for GM 6.6L Duramax engines from 2001–2010. It highlights Whisper Technology and removal of water, air, and debris from diesel fuel, with a 2-micron filtration rating.
This is a better choice for shoppers comparing filtration specifications rather than looking only at flow rate. Check the manufacturer’s fitment details against the specific LB7 year and truck before ordering; the supplied product features do not itemize all included installation parts.
Limitation: Its stated 100 GPH flow rate is lower than the listed 150 GPH AirDog and 160 GPH PPE options, so compare flow needs as well as filtration.
AirDog FP-100 Duramax Fuel Pump
Best for: Shoppers looking for an AirDog pump kit listed for 2001–2010 Chevy Duramax applications. The product name identifies it as a PureFlow AirDog FP-100 fuel pump. Its provided feature information mentions a lift fuel pump diesel truck kit and plastic ties.
Choose this if you want to compare the FP-100 listing with the AirDog 150 GPH system above. The supplied details do not state a flow rate, pressure setting, filtration rating, or no-drill mounting feature, so do not assume those specifications based on another AirDog model.
Limitation: Confirm LB7-specific fitment and the kit’s complete contents with the seller or manufacturer before buying, since the supplied feature list is brief.
PPE Diesel Fuel Lift Pump
Best for: Buyers comparing higher-flow pump options. PPE lists flow of up to 160 GPH, a 1/2-inch NPT inlet and outlet, and a reusable internal fuel filter. The product description says the pump eliminates vacuum from the fuel tank to the high-pressure fuel injection pump.
This option is selected for its stated flow capacity and reusable filter. The product name references Duramax, Powerstroke, and Cummins engines, but the provided information does not specify LB7 year-by-year fitment. Check the exact application and installation requirements before ordering.
Limitation: “Up to 160 GPH” is the stated maximum; the listing does not provide operating conditions or a specific LB7 installation kit inventory in the supplied details.
1R-0750 Fuel Filter Kit
Best for: Owners who need replacement filters rather than a lift pump. The listing states that the kit includes two filter sets, names several replacement filter numbers, and lists compatibility with 2001–2016 Chevy and GMC Duramax engines, including LB7.
This product can be relevant when maintaining a fuel system, but it is not a lift pump kit. Compare the replacement numbers with the filters currently installed and verify the exact application before ordering.
Limitation: It provides filters only according to the supplied information; it does not describe a pump, pump flow rate, or pump installation hardware.
Buying Guide: How To Choose An LB7 Lift Pump Kit
Does the kit explicitly list LB7 fitment?
Start with the exact truck year, engine, and configuration. The AirDog 150 GPH listing specifically names LB7, while the FASS and other listings describe broader Duramax ranges. A broad engine range is not a substitute for checking the manufacturer’s fitment details for your vehicle.
Should you compare flow rate or filtration first?
Compare stated flow rates only when a listing provides them: AirDog’s featured system states 150 GPH, FASS states 100 GPH, and PPE states up to 160 GPH. These figures alone do not establish which system is right for a particular build. For fuel cleaning features, FASS specifies 2-micron filtration and water, air, and debris removal; AirDog 150 GPH says it removes air and vapor.
What comes in the kit?
Check the full listing for pump, filters, wiring, brackets, hoses, fittings, and installation instructions. The supplied details do not confirm every component for each product. Do not assume that one model’s installation features or included parts apply to another model from the same brand.
Is a filter kit the same as a lift pump?
No. A lift pump moves fuel, while the 1R-0750 product is described as a two-set filter kit. It may be relevant for filter maintenance, but it is not a substitute for a pump system.
