    fuels lines

    does the supply line from MFI pump to injector pump and return lines to the tank need to be any greater psi rating then 50? or should you use injector rate line 200psi

    50 psi rating is plenty John, supply from pump is about two bar, and return side is less than 1 bar. Only lines from pump TO the injectors are 250 psi.

    Ed.....the hard lines in the tunnel TO and FROM pump and filter, I presume the larger OD line is the return and the smaller the supply...?
