I don't want to buy more fuel line that I need, so how many feet do I need for a feed line and return? I was told about 38 feet, does that sound about right? thanks
I bought 20' for my feed line and I had about 2 feet left over. I run a line from the hat up to the firewall. Then I have a wye block and feed the back of each rail. I am returnless.
So 38' sounds believable. Because you will need some line in your engine compartment to go to your regulator and other stuff.
Dont buy 38ft of the same AN Size please...
Buy 20ft of -8an for supply, get a magnafuel filter and a Y- block for fuel and then run it to each of your rails.
Buy 20ft of -10 an for return off your rails to the regulator and then back to the tank.
This way you have enough ft to tuck the fuel lines cleanly and wont be short.
