This kit requires the installation of a supplied Fuel Module Upgrade Kit in the fuel tank.

 

The Pureflow AirDog II 5G 100GPH A7SPBD354 lift pump, or Fuel Preporator, is a must have upgrade for your 1998.5-2004 24V 5.9L Cummins w/ in tank fuel pump. The fuel system on a Cummins is the heart of the vehicle’s performance and reliability. This low pressure (preset at 15-17 psi) lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side hooks directly up to the included Fuel Module Upgrade Kit installed in the tank bypassing the factory in tank fuel pump. The pressure side line connects directly to the side of the CP3 injection pump bypassing the factory fuel canister.

The II-5G Cummins fuel pump features a fully adjustable (7-55psi) 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 seperately). The AirDog 5G 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 2 5G DF-100 Cummins lift pump will solve the infamous P0087 & P1093 low fuel rail pressure codes. This positive supply of purified fuel 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), that mount to the pump, filter your fuel down to a 2 micron rating which surpasses the stock fuel filters filtration capability. (see How It Works)

This AirDog II 5G 100GPH Cummins lift pump is recommended for trucks that have a stock to a mildly upgraded fuel system (meaning mild or stock injectors, injection pump, and tuning). See How To Choose A Lift Pump. Backed by a lifetime warranty.


The AirDog II-5G DF-100 for the 98.5-04 Cummins is engineered with the most proven, quiet and reliable motor technology on the market.  It also retains the “demand flow” capabilties of the previous AirDog II systems.  This means that is has a constant supply of clean, pure fuel available for your injector pump at all times.  Any fuel not used by the engine is simply recycled back to the tank, so it will never “over-fuel” your system.  The II-5G A7SPBD354 uses the same better-than-OEM fuel filter (FF100-2) and water separator (WS100) as the previous AirDog II models.  Pureflow AirDog products are manufactured in Shelbyville, Indiana by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.
