Quote: The stock replacement steel lines (3/8" supply, 5/16" return) work great on the pressure side of my EFI setup. Mine is a ~550 HP 496 with pump rated for 700 HP. Would probably work fine with higher HP as long as the pump has an un-restricted feed (pump in tank or sump with -10 lines or bigger feeding the high pressure pump inlet).
My concern is I have the smaller lines and didn't think they would be sufficient. I figured I would need to upgrade and looking at the cost of the prebent stainless lines they are about the same cost as going with larger push-lock or stainless braid. I figured why not upgrade for the future?
