just blocked off the return line and done a prime, fuel pressure went up over 100, and still dropped off, maybe its my cheap fuel gauge? According to my data logs the car is running rich, low blms 104 106 in cell 4, the other cells is not so bad 113-114, 118-119, I also noticed in my log high o2 reading when high, just replaced o2 sensor with AC/delco. Car has a Solomon tune, hes the one who told my the car is starving for fuel at WOT, that's why I changed the pump.
Any suggestion would be great. Maybe I missed up pump connections? Gotta trap door cut.
