I have a 1995 mustang GT just got done putting a procharger on it. And during my tune i was told that the stock fuel rail wasnt able to get enough fuel to the injectors. does anyone know the limits of a stock fuel rail. I have 42lb injectors, 255lph pump and we were getting about 10 pounds of boost when it would lean out. Any ideas??
stock Fuel Rail How much can it handle

Well...The regulator controls how much pressure is in the rail. i would assume you have an adjustable regulator and your tuner knew to adjust it but thats where i would start looking. Fuel pump and filter might be the problems as well.

it's built for speed not longevity, woman
Did you use the supplied FMU that came with the kit? I cant tell you how many problems i had with mine from ATI.
and if you arent using the supplied FMU you are going to have to have an adjustable regulator and a competant tuner

The 94-95 Mustangs had the big fuel rails, I read somewhere that they flow nearly as much as aftermarket rails, they're an upgrade for a fox. Look someplace else besides the fuel rails.
I am making about 42 psi at the fuel rail, and when i get on it it jumps to around 50-53 and never drops?? any one know why the left bank would be running lean
