Hello! I've built a stock block, forged Eagle 347, X302 heads, Anderson B41 Cam, Procharger D1SC Blower. I'm set on ditching the stock fuel rail and fuel lines. I would much rather run the fuel in and out from the passenger side back and not the front. I'm running a 255 pump but while I'm changing things should I go with a larger than stock feed and return line size? I've found some larger hanger/sending unit setups online but are they necessary? Would a -10 AN feed and a -8 AN return be too much overkill and would the 255 be able to maintain enough flow during WOT?
