quick fuel line question
with either 6an or 8an to the front what size line should i use for the return or is the stock good enough
also what size do you guys recomend for any where between 600 and 800rwhp FI
I have a nice amount of 4an but the stock lines look just as big or bigger thanks for any help
Anyway, as a generic response for you, itd be wise to run at least -8 feed line to the rails with a y-block at the rails, and a -6 line for the return from the regulator back to the tank. Some use the stock feed line as the return line when the upgrade the fuel system.
-4an line is for nitrous, or a fuel system on a honda
