PureFlow AirDog 89-93 Dodge 12V 5.9L Cummins FP-100-4G Fuel Pump A4SPBD136

The Pureflow AirDog FP-100 4G A4SPBD136 lift pump, or Fuel Preporator, is a must have upgrade for your 1989 – 1993 Duramax. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (preset at 10 psi) Duramax lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side connects directly up to the factory suction line on the frame rail.  The pressure side connects to the factory injection feed line bypassing the stock frame mounted low pressure pump.

DESCRIPTION:
The 4G fuel pump features a fully adjustable integrated diaphragm pressure regulator. This regulator offers more consistent fuel pressure and allows for higher flow rates at pressure.  It can also be boost compensated to battle any pressure drops under open throttle (boost compensation kits sold separately). The AirDog 4G also includes an updated 12 gauge wiring harness with Metri-Pack 280 connectors, which allows for higher current flow without creating excessive heat.

The AirDog FP-100 4G Duramax A4SPBD136 lift pump will solve infamous P0087 & P1093 low fuel rail pressure codes. This positive supply being fed to your injection pump will also add performance, throttle response, and longevity to your vehicle. Due to extra stress on your fuel system from either high mileage and/or additional performance modifications, like a tuner or larger injectors, your injection pump can become weak over time. This may result in a drop of performance, reliability, and fuel economy. The supplied water separator (WS100) and fuel filter (FF100-2) mount to the pump. They filter your fuel down to a 2 micron rating which surpasses the stock fuel filters filtration capability.

This AirDog FP-100 4G Duramax A4SPBD136 lift pump is recommended for trucks that have a stock to aggressively upgraded fuel system. Therefore meaning stock to larger injectors and injection pump; will also support aggressive tuning. Perfect fit for daily drivers to performance applications reaching up to 1,000 RWHP!  Backed by a lifetime warranty.
