Fuel pressure w/dual tanks 96 4.9l
I got a PO171 code (system lean bank 1) the other day. I changed the fuel filter and check fuel pressure, here is what I got...
engine running 42 psi on both tanks
key on engine off 42 psi rear tank, 30 psi front tank.
Why do you think I get the same pressure from both tanks while running?
Before I buy a expensive fuel pump is there anything else I should check?
Am I correct in assuming that my fuel pressure regulator is OK?
If I remember right, the code came on after I changed tanks.
Thanks for the help!!
