Posted April 15, 201510 yr On the drive to work today, made it about 4 miles. Pressure dropped to 12 then 10. Found a place to turn around pressure dropped to 0. Now the wiwrd part about one mike later pressure pegged high on my isspro electric gauge
May 15, 201510 yr question for the class, i currently have an AD2 165 and so far i have had little issue with it, the current issue i have seems to be around the regulator. it seems to have a pretty wide swing from idle to WOT (about 5 psi) very repeatable so i know its not the pump its self. I just wish the regulator has a tighter res. anyways, my question, I was looking at the fuel boss, and since i already have the .5inch line kits from my AD2165. can the fuel boss just piped in series? IIRC the AD does have a check valve that is surposed to allow bypass if the pump was to fail.
May 15, 201510 yr if you got a fuel boss, there seriously wouldnt be a need for the airdog, unless im missing something. the fuel boss sits under the engine front damper. Mechanical pump in my eyes will always surpass an electrical. One nice advantage is when the rpm increases so does the psi so there is no WOT psi loss as you would see otherwise. and yes i know some dont see a psi drop with electrics, i just like the fact that i dont have to worry about wires shorting or fuses blowing or motors burning out or valves going bad etc etc.
May 15, 201510 yr well the idea of keeping the AD was for priming and the continued use of the filter assembly, the factory fuel system is all but gone. so i will still need the filter assembly
May 15, 201510 yr Video of pressure fluctuations Raptor 150 pressure fluctuations: https://youtu.be/Z6mYCIBXxuw 20 - 9 psi swings with my old raptor. I gotta admit my newer pureflow fp-125 ( not airdog) lift pump is going great. No issues.
