Product Description

The AirDog R4SBD052 Raptor 4G 150GPH Fuel Lift Pump is a premium aftermarket diesel lift pump engineered to deliver a consistent, high-flow fuel supply to your 5.9L 24-valve Cummins engine (VP44) in 1998.5-2002 Dodge Ram 2500/3500 trucks that do not use a factory in-tank fuel pump. By replacing the stock fuel delivery setup with this dedicated high-flow system, you can eliminate fuel starvation at higher RPMs, improve throttle responsiveness, and better support common performance modifications such as larger injectors, tuning, and turbo upgrades.

This system uses AirDog's 4G technology - a robust design featuring a 4-bearing motor with an intermediate shaft and a gerotor pump - to provide reliable performance while drawing fuel via a suction connection to the factory fuel module and delivering pressurized fuel to the engine's fuel filter housing. The integrated regulator is preset for ideal delivery but can be adjusted for specific tuning needs. Installation is simplified by the included wiring harness, mounting hardware, quick-connect fittings, and fuel line, with no return line required. The kit comes complete with everything required for a clean frame-rail mount and a lifetime limited express warranty from AirDog/PureFlow.
