Size of fuel line for FI I am building a supercharged 6L . I an wanted to know what size of fuel line I shood use ? I was thinking -8 or -10 for the feed line , and -6 for return . I am trying to support 1k hp I a 99 F body. What are u all using?
-8 is prob enough. -10 even better.
Id keep the return and feed the same size. There is no reason not to. Remember that at idle and light throttle, nearly all the fuel is returned to the tank. You dont want pressure in the return line.

Ya what kind of fuel. If its 93 octane with meth injection you could use the stock line. If its e85 you would go with a -8 or -10 feed and the same or slightly smaller for return.
Mine did 900whp with the stock feed and the evap as the return. But I use a lot of meth so my injectors are only at like 60%. Basically it depends on the fuel you are using.
