Some time ago I posted about the steel fuel line that supplies the injector pump on the boss' 01 breaking, and that we decided to cut the fittings and a couple inches of tube off each end and replace it with a rubber line. I can't rememeber when it was, but it's been trouble-free since.

The banjo fitting was breaking off the end of the tube, right at the edge of the solder/braze/weld.
