I bought a used Irate basic fuel system with walboro gsl392 pump, after a few months it went out so I used my old stock pump with 160k miles on it and bought another new stock pump to run in parallel. since then the truck will not hold 65psi when in the pedal, even on stock tune. Ive tried replacing both filters, working all kinks or bends in suction side, pressure side doesn't have any signs of kinks im just stumped.
Tried plumbing one pump in at a time and each single pump would only make 42psi no mater what I did with regulator besides literaly just about dead heading it
Tried pressuring up the fuel tank through the fill cap 3-5psi to "push", the fuel to the pumps seemed like it would still go down when just reving it up a bit.
details on the system ive put together is from tank..... steel 5/8 pickup tube> 5/8 line to filter base>30mic water separator> 3/8 Y into pumps> 3/8 Y out of pumps into 6mic filter> 3/8 line up to back of heads and a Aeromotive regulator..... I spliced into existing factory power wires for one pump and ran separate power wires from battery with the help of a relay. truck has 230/100's
