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.

I've about 600 miles on the system, heavy towing, no issues so far, my problem with the system mainly comes from the customer service. When I received the system it was packaged with a broken plug on the pump. The snap to hold the male end in place was broke off, it was packaged and shipped like that. I also contacted AirDog about the amount of hose that came with the kit, one person emailed me 14ft, another person on the phone told me 20ft. I received 14ft, and they told me I would have enough even after explaining to them I have a cab and chassis truck, with a tank behind the axle.
Was very easy to install with the push fittings, it arrived early and was packaged safely. Always happy to do business with RiffRaff
