Custom Fuel Return Line

[Blown331LX]

I need to install a 1/2 or 8-AN fitting into my stock EFI gas tank. The tank is steel and all the weld in fittings I can find are aluminum, which u cant weld together. I DONT want an entire baffle all i really need is a fitting but cant find a steel one, HELP. Any one done this any other ways before? What works what doesnt? **I posted then started thinking while sipping back some cold ones....?SOLUTION? .....standard pipe thread and AN thread is different correct? Well then thats fine. Lowes carries 1/2 steel weld bungs like many other places online, the tank end will have a 1/2 steel weld bung coller with thread in 1/2 barbed hose fitting, hose clamp on return line to this fitting and the other side is at pressure regulator which is AN style. This will work right? What type of hose and AN fitting style would be best? All advice welcome....

Steel hydraulic fittings have the same 37 degree flare as AN fittings.

AN fittings require a 37 degree flaring tool. A standard automotive or household plumbing tool is 45 degrees and cannot be used with AN flare fittings. If you do, the flare is subjected to too much stress when the fitting is tightened, and is likely to fail or leak.

See http://www.mscdirect.com/ , http://www.mcmaster.com/ or for the flaring tool you will need . Prices start at $75 and go up
