I use Aeroquip line with -AN fittings.
Very flexible and easy to use, looks great too.
Price will be high for most.

Speed shops and Summit racing have it.
If you know your lenghts, there are many used pieces available from Nascar teams on eBay.
Some that I have purchased that way have been pennies on the dollar.

-AN sizing goes like this:

-4AN = 4/16 or 1/4 inch, roughly $8.00/ft. and the ends ~$25@

here is a reference site:

Hope this helps.

Subject: has anyone fabbed up 316-stainless fuel lines?

i'm curious if you copied the hard plastic line shape, or made your own.
and did you start with straight pieces, or a coil.

thanks in advance.
