Tom-
On to the questions;
1.Yes they use a special alloy.
2.I'm not a chemist, but what he's saying is that copper reacts with the fuel
to form ,( at a faster rate), what most people call varnish.
3.No. It means gasoline.
4 Yes. I wouldn't want to be the guinea pig in determining how many tanks of
gas it takes to gum up the fuel system. BTW, I've never seen a copper fuel line
and I've seen the undersides of at least 40,000 cars.
Just my 2 pfennigs..
