I’m running an aftermarket tbi setup on my truck. The place is currently closed til Monday and I’m having some issues. Fuel system setup is as follows and all new:
17 gallon cell with pickup and return ports in the bottom. Cell is about 1’ above the pump and 18” reward of the pump.
All lines are -6 braided stainless feed and return.
Running stock gm tbi in-line filter
P5001 20psi pump they recommend.
Marshall liquid filled vibration proof 0-60 psi gauge at the throttle body.
According to them I should have 15 psi at the gauge and the regulator in the throttle body will pull it down to 10-13 psi. I’ve ran several different pumps of various brands in the 15-20 psi range. The most I can get at the gauge is 9-10 psi. Anyone have any ideas as to what my issue could be?
