Standard kit:

This is the AirDog® II-5G DF-220 fuel system for the 1994-1998 Dodge Ram P-Pump 12V Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A draw straw is installed in the fuel tank to supply fuel to the pump.  The pressure side connects directly into the side of the P-Pump, bypassing the factory fuel filter housing and block mounted pump. The injection pump return is tied into the engine return to eliminate the need for the factory filter head. The AirDog® Air/Vapor return is sent back to the tank through the filler neck return tee.  This is a 220GPH (Gallon Per Hour) lift pump system for heavily modified trucks. Check out our installation manual for a list of parts that are included with this kit.

Standard kit + Sump

The PureFlow AirDog® universal fuel sump helps aid aftermarket fuel systems by utilizing gravity to pull fuel from the tank. Our redesigned sump has both a suction and return port! We integrated a dual o-ring seal to prevent leaks! The installation of our fuel sump eliminates the common 1/4 tank suction issue associated with a draw straw-style fuel pickup. This sump is manufactured in America using corrosion resistant components.

The PureFlow AirDog® Fuel Sump Advantage:

- Can be Installed Without Dropping the Fuel Tank

- Eliminate 1/4 Tank Problems

- Feed and Return Port

- Uses Corrosion Resistant Components

- Installation Takes Less Than an Hour

- Dual O-Ring Seal

Our Take: 

 For the most ease of install, you will want to utilize a sump on the bottom of the tank. 

Anyone who has issues with the reliability of a electric pump versus a mechanical pump has probably had their factory first gen wiring fail them. There is NO warranty for the pump not working due to you not fixing your $h!tty factory first gen wiring.
