    enough fuel for 12lb's of boost?

    I am currently running a 255LPH in tank, and plan to run probably 12lb's of boost. I am also stepping up to 42lb injecotrs. Will that be enough fuel? Or should I also get an inline pump, of so what would be good? thanks.

    just found out that the t rex could actually be a restriction to the 255 in tank.

    i have a t-rex in line with my 255 in-tank and my air/fuel ratio looked great. i didn't have a fuel problem at all. now if you didn't buy the t-rex yet then i'd get a 255 in-line pump.

    AaronC was the one who told me about the restriction. he was told the t rex flows like a 190lph.
