Here is the aluminum fuel line I'm
going to use. It's 1/2" diameter X 25 feet long. Now this stuff is
easy to work with compared to stainless tubing.

After cutting a piece 32" long, I
needed to give the end a 37 degree flare to match the AN fittings I'm
using. If this flaring tool looks familiar, that's because it's the same
one used for making my brake lines and it can handle seven different sizes of
tubing. All you have to do is make sure the end of the tubing is flat
and square with no burrs and then make the end flush with the top
surface. Clamp it in place and then put on the top clamp with the taper inside
the tube. Crank the handle a few turns and there you have it.

There are two parts to these fittings
that get used on tubing. The flare and the nut. If you have any kind of
bend in your tubing, then you need to put these on prior to flaring the
end. Believe me, it's easy to forget.

The other end needed a slight bend in
it. This bend was necessary to run from the fuel pump over to the frame
rail. The way I bent it was just by hand. I went slow and did a little
at a time. Now we're ready to test the fit.
