Model A Fuel Tubing - Where?

I bought some 1/4" Fuel line (because are doing a custom fuel delivery to a fuel pump and a Weber) on Amazon (1/4" OD Aluminum Hard Fuel Line Hardline Tube Tubing Coil 10 Feet Roll), and the tube is too big for the compression fittings that came off the original A fuel lines.

Questions:

Can aluminum be used for fuel lines?
Where to get the tubing (maybe it is Cupronickel) for fuel lines because the aluminum to large tubing from Amazon was too flexible? Maybe 5' of tubing?

Model A fuel tube can be bent, but it is still pretty rigid.
 
Whatever solution you come up with, the Weber will require a small length of rubber tubing at the carburetor because of normal engine vibration and movement.

I have never seen aluminum fuel line. Normally it is steel. I have seen copper but copper has a way of breaking from fatigue.

Many many years ago the fuel line on my 30 coupe starting leaking. It was rolled steel where there was a seam down the length of the tubing. Vibration had caused the seam to start leaking. It was either an original tube or a cheap replacement.

You have to use Alloy AN fittings with Aluminum fuel line. You need to get the proper size steel tubing and brass fittings.

Your local O'Reilly's should have what you need.

I used steel tubing when I fabbed up my ball valve gas shut off.

I would use copper alloy brake/fuel line tubing which comes in different sizes. It is very easy to bend, seamless, non-corrosive, and flares very easily.
 
For safety and longevity, you should not use copper or aluminum for fuel lines. Both are soft metals that are easily bent and manipulated, but they both tend to crack when subjected to vibrations like found on an A.

Use only rubber or steel based materials for fuel lines. Use a handheld tubing bender to form your lines, and brake lines do make great material for a fuel line in an A.
 
O'Rileys has steel brake line in different diameters and lengths. You most likley will have to ask for it, as it's usually in the back room. Your biggest obstacle will be finding the guy in the store that knows what it is and where it is!
 
I bought a roll of 1/4” steel line, and all the 1/4” compression fittings work fine. Have you miked the line and the fittings to if they are correct?
 
Aluminum, brass, bronze & copper should not be used as fuel & brake line materials because the work harden by bending cold and also from vibration, so they become brittle. Only annealed steel tubing should be used for fuel and brake lines.
