Yes Diesels use steeel for the high pressure lines, but have you looked at them?
The wall thickness is many times that of thin wall copper. And copper is less
brittle only until it hardens .

Yes there is a difference in copper alloys. Don't know why your copper line on
your tugboat has lasted so long, but if you take a look at any vehicle on the
road, none of them use copper for fuel lines, gasoline or diesel. There's a
reason for this. :-) Joe
