Ok.. this is for guys that are running double in-tank pumps.
I'm trying to do a "rule of thumb" diagnosis on a fuel system.
Can you engage both of your fuel pumps with the key on, motor not running and tell me what your base fuel pressure does? What was your base pressure and what does it climb to?
My friend's car bumped up 5psi from the single pump base. I expected it to climb much more than 5psi because of the limited relief/return on a stock fuel lined car.
I understand that the "best" diagnosis is flowing the pumps, but that's hard to do correctly at full pressure.
Thanks in advance for your help.
