fuel pressure and filter
i have a bg280 pump, filter is between fuel cell and pump, it's a bg5000 should it be on other side of pump or does it make no difference .........its worked fine for years but noticed fuel pressure has been eratic verry low 3-5 psi down track .......i was riding th car around in the pits warming it up and noticed fuel press was on zero i turned the fuel pump switch off and then back on it jumped up to 8 where it usually runs .........replaced regulator still no good 2nd round when i hit TB it fell on its face i thought it was going to die but it recovered just not fast enough ......... i went back to trailer hit TB before i cut it off it went right up on RPM against 2 step ...............i checked pressure at pump it was around 14 removed pressure relief spring shimmed it got press up to 21 could th press relief have been sticking or press set to low from manufacture im sure rasing press on pump will help ..........just wanting to hear th thoughts of others thanks
