I just noticed in the Summit Racing Catalog, whilst glancing through it,
they have aluminum fuel line in bulk lengths. I was contemplating using
this for the return line on the Spitfire for the fuel injection conversion.
I can't see any problems other than aluminum can sometimes metal fatigue
if bent too many times, or with severe vibration. Some aluminum alloys
will oxidize more readily than others, but considering that it has to be
bendable it would probably be of a grade (6060?) that is corrosion
resistant anyway. Besides, steel oxidizes too - I don't envision any of
these conditions, and it would sure be easier to bend to fit than the steel
lines I used for the pressurized side (15 lbs). As I recall, the crossover
line between float bowls on Holley four barrel carbs is or at least was
aluminum, and I have never heard of any problems with those. If any one
has any experience or information as to why it wouldn't be a good idea, to
use aluminum for use in the return fuel lines, please drop me an E-mail.
In my advance age I may be forgetting something I learned earlier about
using aluminum for fuel lines -
