Aluminum fuel lines, thoughts?

[RJRENTON]

My personal comments:
First choice is STEEL TUBING of the appropriate size and corresponding AN fittings to match
Second choice is STAINLESS STEEL TUBING of the appropriate size and corresponding AN fittings to match
Never copper tubing or aluminium tubing because the risk fatigue failure (cracking) due to vibration
Just my preferences.....

If you are looking for something easy to work with that will mold up better than Al I would go with copper nickel hard lines.
