        I am not trying to be a problem here, just want some guidance. Russell twist lok is NHRA approved as well as many others in this list. http://www.nhraracer.com/Files/Tech/NHRAAcceptedProducts.pdf The NHRA rule book allows them except in areas that could be cut by flying debris from flywheel area etc. Any thoughts on non-metallic braided lines instead of metal. Just tell me to go all metal if that is best. Thanks

        Like metal lines are going to survive a blown clutch or any other 7000 rpm shrapnel any better than rubber ...lol

        I try to minimize use of rubber hose but really ?
        Its like the rule that you have to have your conv. top up.

          Street/ strip car. do you have a tank ? if not get one, fuel gauge ? 1/2 " sending unit, a 25' coil of 1/2" aluminum fuel line.
          That will get you started for about 350 bucks. street car right?
          I don't like fuel cells for a street car unless it is mounted where the original tank is.

            I think you'll find that if you interpret the rules correctly. Any fuel line that passes near the area you speak of, has other special instructions to follow. It reads something like this:

            Fuel lines (except steel braided lines) in the
            flywheel/bellhousing area must be enclosed in a 16-inch length of
            steel tubing, 1/8-inch-minimum wall thickness, securely mounted as
            a protection against fuel-line rupture. Fuel lines may not be routed
            in the driveshaft tunnel.

              The OP is starting from scratch I believe. He can build a nice fuel system fairly inexpensive and not have one inch of rubber.

                Even though it may not be a NHRA event most tracks have a policy that says "NHRA safety rules apply " check with the track . They all have e-mail and telephone . Fuel line : I'd use 1/2" or -8An for that 512 cu.in.

                  Unless it a high pressure fuel inj. system , 3/8 will definitly feed it .

                  expand your mind grasshoppa. there is also an adjustable wrench, a socket wrench, a lighter, and a boxmod vape in the pic too :)

                  tbh, the compression thingies came with the B&M transmission gauge kit I was plumbing in, and those damn brass Ts are like 8 bucks up at lowesdepot, so I was just using what I had.
