Hard to decide which thread to revive sometimes, but this one gets peoples' attention, so...
I tried to remove my fuel line today, and it absolutely wouldn't budge from either the fuel pump fitting or the injector fitting. I was wary about bending and twisting and pulling too much on the plastic fuel pump fitting, so I finally just cut the hose off. Since the brass fuel injector fitting is much sturdier, I did plenty of bending and twisting and pulling and even prying, but again, it simply wouldn't budge. I finally had to cut it off that end, too.
Any advice about future maintenance? Should I lubricate the fittings when I fit a replacement hose? I plan to follow the advice here regarding hose spec and clamp suggestions...
