Szester Posted March 31, 2010 Report Share Posted March 31, 2010 Bump, is this normal? Link to comment Share on other sites More sharing options...
freetoskate124 Posted March 31, 2010 Report Share Posted March 31, 2010 If it helps at all, I redid all the clamps/hoses/whatever around the fuel pump and I don't hear any sucking like that. I also have good fuel pressure (something like 60psi idle and 90 or 100psi under 5lbs or greater of boost) Link to comment Share on other sites More sharing options...
JAinsworth Posted March 31, 2010 Report Share Posted March 31, 2010 If it helps at all, I redid all the clamps/hoses/whatever around the fuel pump and I don't hear any sucking like that. I also have good fuel pressure (something like 60psi idle and 90 or 100psi under 5lbs or greater of boost) That is way too much fuel pressure. You should have around 38 psi at idle and increase one psi of fuel pressure for each psi of boost. e.g. 5 lbs. of boost should have 43 psi of fuel pressure.Jimmy Link to comment Share on other sites More sharing options...
freetoskate124 Posted March 31, 2010 Report Share Posted March 31, 2010 To be honest, my numbers are off because I had the fuel pressure gauge hooked up a longggg time ago.(forgive my fuzzy memory, college is putting more mental strain than I would like ) Those numbers (38 to 40) sound better Link to comment Share on other sites More sharing options...
