Tom;
I had also read the Dimebank article at the VTR site and had based my reply on
that and my own experience. After doing some more research however, I have
found some sources that state that using copper for fuel line is acceptable.
It is common on boats and yachts. I realize that although I may have seen a
lot of vehicles, I do not see many that are owned by DIY'ers. Come to think of
it, most cars I see will be available for crushing a couple years after their
last car payment has been made. A couple mechanics I asked wanted to know why
I'd "go to all the trouble, they sell fuel line at the parts store", but
otherwise couldn't offer any reason not to use copper.
Maybe I'll do some more research.
