    What's everyone running as far as fuel lines go for a fuel injection setup?

    I am serious about switching from carb to efi and trying to get everything locked down. As what I need for the swap.

    I know I'm going with a tanks inc tank and pump. Setup

    Also going with fitech efi.

    I know I have to switch the lines out, did you'll just take the line from tank to where it comes up in front and get a one piece solid line made or what was done?

    Thank you

    I ran braided stainless a few years ago. -8 I believe. although I don't currently have efi, I will use what is there if I do make the switch in the future. extremely easy to install.

    3/8 hard line from tank to bulkhead, then -8 braided from that to the fuel rails. The 5/16 hardline as a return.

    I modified my fuel tank to mount the pump on the bottom of it and put a sump on the bottom for it to draw fuel from.

    thank you for replying.

    where did you get the 3/8 hardline? was it pre made or did you have to take your old one off and get it made to match?

    thank you

    I bought a coil of it and bent it up myself. Easy enough, just take your time.

    I have toyed with the idea of running braided stainless the entire way but my gut tells me I should run hard to the engine compartment and then braided, like flak monkey did. I wouldn't want something on the road causing a break in the line.

    So where in the engine bay did ya'll terminate the hard line and transition to flex? Looking for a clean tucked up out of the way fuel line.

    Never worked on an LS - getting ready to install tank and run ss hard line and don't have the engine in yet to see where everything mates up...

    thanks.

    I plan on using this "bulkhead" area to secure the end of the hardline and then run braided line to the fuel rail.
