Fuel Pressure probs
So I have my new BG 650DP speed demon on and running now. The last two days have been raining non stop so I hadn't taken it anwhere to get tuned yet til today....
I installed at the same time a Russell fuel line with gauge. With only me tuning and it running bad I had 6psi+ up to 8 sometimes on the gauge.
now with my mate tuned it all up good, idles and runs smooth yet the gauge shows below 3psi pressure? this ain't good!
now the motor has been on a dyno with a holley 650dp and the AFR was fine to 6,000rpm, why would the BG make the pressure drop so much?
anyone got any ideas?
