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.

I am not replacing any hard lines only adding one from the rear of the car to the front

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.

Does anyone know the id/od for porsche steel fuel lines.
I did a search no luck

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

Some wanted info may be these threads

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

Eastwood sell 5/16 brake line which is a match for the fuel line on my 69

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: http://forums.pelicanparts.com/showthread.php?s=&threadid=222204&highlight=earls+ fittings

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.
