Part Number:

PureFlow AirDog II Air/Fuel Separation System DF-165 Powerstroke 7.3L

The AirDog® II Demand Flow Fuel Preporator®

This new model Fuel Preporator® improves on the original by offering demand flow, so that the unit only draws as much fuel from the tank – through the tank module – as is required by the engine, and then returns only air and a dribble of fuel to the tank. What does this mean? Connecting to the tank module means there is no need to drill holes in the fuel tank to install an aftermarket fuel draw straw, so installation with the included fittings is QUICK and EASY. The AirDog II also features either a preset or adjustable stainless steel pressure regulator.

Alternative for the Powerstroke fuel pump.
