Sources for steel fuel lines

I am revamping the fuel system in my 911 race car (carbs)
What is a good source for steel fuel lines?

Why not use hydraulic steel tube and JIC flare fittings? Cheap, relaible, easy to bend, and pressure rated.

Look in the yellow pages for a hydraulic supply house.

Do you have a picture of the fuel lines you want to replace? I might be able to help you.

the fuel inlet and return "hard" lines exit the tunnel in my car with a coupling to rubber lines. I disconnected the 2 rubber line couplings and brought them + hoses to a hose shop. They used the couplings on 2 ss 6AN hoses.

I believe you need 3/8" supply, 1/4" return.

Some wanted info may be these threads


68 911 Fuel System



3.2 Carrera engine swap: fuel system changes

Also it may have been member Jim Sims that posted a list of fuel lines ID & OD at one time.

Pressure line is nearly 5/16", which is a common hardline fuel line size. Porsche factory used 8mm OD on many early cars. I revamped my fuel system like this: AN fuel fittings for fuel system 8mm ~ 5/16th"

As you'll see in that thread, 8mm is VERY close to 5/16".

I'd order 5/16" hard line in bulk from Summit. I think you can buy Stainless or mild steel or AL.
