Was wondering what fittings are being used with AD or FASS fuel systems to keep the stock filter housing in line.I live in the northeast and would like the security of having the fuel heater,also an extra filter cant be all that bad. I have a AD II 165 1/2 fuel line with quick connections and modified fuel canister(which im having problems with since ive installed but thats another story for another time).

I connected my ADII straight to the oe canister with the fittings supplied with the pump. Just conect it straight to the canister instead of the VP. I then used a big line kit from Vulcan Performance to connect to the VP. It came with the necassary fittings.

Thank you for the reply. my problem is that my AD did not come with any extra fittings except for barbed tee's and the fittings for the pump and module only.I will check various venders and find some fittings to make this work. Once again Thank You:thumbup2:

I'm the same way...Fuel Tank -> AirDog 150 -> Stock fuel filter / heater -> VP44Only a 2-3 PSI drop typically.

I used the fitting that was supposed to go in the VP. Just installed it on the fuel canister instead of the VP. That s on an 02 with the later model fuel canister. The big line kit came with every thing to connect the canister to the VP.

I use JIC 90 degree push locks, steel. 3/8" or 1/2" which ever you desireGet em at a hydraulic hose shop or Glacier Diesel sells 'em too but they charge more

Yes sir mine did to just looked at it today,and mine is a 99. Im ordering the Big Line kit. i want to get rid of all my quick-connect connections. i think they are the reason my fuel pressure fluctuates so bad(0 psi-25 psi) and also the AD pump, but according to pureflow The lift pump is not the problem. On to more diagnostics i suppose.

What's the thread size on the oem filter and vp pump?

Do you have anything on your fuel gauge to isolte it from the pulses of the vp? They will cause your pressure to jump up and down and eventually take out the gauge. I have a needle valve installed on the tap for my gauge. It is barely cracked open and isolates the gauge from the pulses.

They are the same,I just dont remember what size they are. Maybe someone else knows off hand.

Is the thread of the banjo fittings metric or british,I would like to replace them.
