Well first I will start by asking how much hp can the stock fuel lines hold? I am looking to make 500hp on a turbo setup. I am thinking about redoing all my fuel lines to 3/8" hardline from the tank to the regulator. And a stainless -6an line to the fuel line. The reason I want to run a line from the regulator to the lines is because my buddy has a universal aeromotive regulator he can give me for cheap that I can mount on the firewall or something and then make a y to each side of the line, but the inlet and return lines are -6an.
My real question is when upgrading the line at the tank, does it matter that the lines coming out of the fuel pump assembly is the stock size? Will it even do anything to upgrade the line if the line coming out of the fuel pump assembly is stock? Does anyone sell an assembly with a bigger line if it needs to be upgraded? And if I can use the stock assembly how would I go about connevting a 3/8" line to the stock 5/16"?
Right dont sweat it you'll be fine with the stock lines with those power numbers. Just make sure you have a good pump maybe get another one for inline. peace
