Here is my list of parts this is with a -8 feed split to 2 -6 lines to the rails all Teflon hose. . I was going to feed the rails from the back and then run the front lines to the fuel regulator then run -6 line to the old 3/8 feed line to use as the return. For the feed to the tank I was going to run -8 as close as possible then reduce it to -6 so that I can clamp the -6 on the original feed line from tank I may end up making a new feed line with a-8 end welded on but haven’t made up my mind yet. For the return the plan is to flip a fuel filter over so it flows towards tank and then pick up some 3/8 to ¼ reducers from a local auto parts place.
