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 and II-5G 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.

Key Features

  • Flow Rates of 100 GPH and 150 GPH
  • Built-In Adjustable Regulator
  • Improved Throttle Response
  • Increased Fuel Flow Rates
  • Lifetime Limited Warranty
  • Quick Connect / Disconnect Fittings
  • No Return Line Needed
  • Complete Installation Kit and Detailed Instructions


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.
