At what point does it become neccessary to replace the OEM fuel lines? What is their max GPM/LPH, or max horsepower? I have a single 255 in tank for now and was looking to either add a bosche 044 in-line, or upgrade to a 450lph in-tank pump since I'll be on e-85. Does anyone have any solid info on the oem fuel lines? I.D. and length from pump to rail? or possibly how much the lines will flow at (X) psi?
