Thanks for the info here is a bit more detail. I am building a biplane with
a center section fuel tank. Some of the fuel lines will be out in the
breeze. Still use the 5052-0 in those locations?

I just started thinking about the fuel system for my project. I knew it
was
3/8" but in what alloy?

In the fuselage, usually 5052-0

In the engine compartment, either fire sleaved, teflon lined stainless
braid or (for short runs that don't have to flex) solid stainless.

I am not sure but I think the fuel lines from my wing center section
tank are 3003, and they have a small section of vinyl tubing just out
of the tank. They've been on my Jungster for twenty years, however
I've replaced the vinyl several times as it hardens. I use them to
tell when the wing tank is getting empty as you can see the bubbles
form.

It allows for a little flexibility where the lines enter tank (one on
each side) also I dont have a fuel gauge on the wing tank and it
allows me to tell when it is about to run out by watching for the
bubbles.

Speaking of AUTOS, Jerry....

Over 3 years ago, didn't you promise an auto conversion
that was going to put out 10 gazillion horsepower utilizing
a mere pocketful of cc's coupled to a miracle camshaft?

Since Lycoming is still in business, what gives? )
