You can use cat filters on a FASS 150 titanium. Awesome lift pump :thumb:
Was thinking of going that route in the future. I see FASS came out with a fuel heater... I see that being bennificial to winter driving in this New England climate. Ive gelled my Airdog on my dodge with a LOT of Powerservice in it. The filters hanging exposed like that with a combination of wind, and near 0 or - degree temps takes its toll. Still would like to come up with a system to bypass the pump in case of failure. Possibly a length of hose and a couple three way dump valves? On the GM trucks does an Airdog/Fass installation include plumping new hose from the pressure side to the CP3 and bypass the factory fuel filter? Or does it tap into the existing lines?
