Bill,
I would suggest taking a propane torch to a piece of scrap aluminum (beer can) and a piece of stainless.  It may affect your comfort level about aluminum in the engine compartment.

Personally, I would never use aluminum fuel line in front of the firewall.

If you're going to do that, you might as well include those rubbery pieces of fuel line in the test.  And remember, you're telling that to a guy who has the engine mounted to a plastic airplane 8*)
