Upgrade your diesel’s fuel system with AirDog’s new Raptor 4G Fuel Pumps. The Raptor 4G is an economical performance replacement lift pump for your diesel truck. It uses many of the same components as AirDog’s wildly popular II-4G lift pumps. It uses the same four-bearing motor assembly design with an intermediate shaft which keeps fuel away from the electric pump motor. This also allows for self-alignment of the gerotor, resulting in lower amp loads on the motor. The result is a remarkably quiet and durable fuel pump.
This is the Raptor-4G RP-150 fuel system for the 1998.5-2002 VP-44 24V Cummins with the fuel pump in the fuel tank. This system mounts to the frame rail using the supplied sandwich plate mounting system. A Fuel Module Upgrade Kit is installed in the factory fuel basket to pull fuel through a factory-style 1/2" bulkhead fitting. This will bypass the factory in-tank lift pump. The pressure side connects directly into the side of the fuel filter housing on the engine block. These pumps are internally regulated and do not require a return line. This is a 150GPH (Gallon Per Hour) fuel system for moderately modified trucks.
The new Raptor 4G features a built in adjustable diaphragm-style regulator, which allows for more consistent output pressures. It has a removable and cleanable inlet screen fitting. You can also check and read pressure off the dual-port gerotor cap. Even if you don’t have upgraded injectors or a performance chip, your injection pump will benefit from the constant fuel supply. Save expensive wear and tear on your injection pump with the all new Raptor 4G Gerotor Fuel Pump.
