Anyone know an easier way to remove old fuel lines or high pressure lines that are hardened and stuck on fittings?
 
A hose pick will get rubber hoses off a fitting easily if that's your question.
 
I have used a heat gun to soften old hose ends. OK for water, diesel if you use a low temp setting. Not for gasoline.
 
If you take a sharp utility knife and draw a cut parallel to the hose from the hose end slightly past the end of the internal fitting, then bend the hose so that the knife slit is on the outside of the bend, the hose will usually split and come right off. The object is to cut through the fiber cords of the hose while trying to avoid nicking the the tops of the hose barbs. It doesn't seem to matter if you do nick the barb as the new hose still seals anyway.

Yes, and also DO NOT LET THE BLADE SCRATCH THE FITTING!!! It will ooze drips no matter how tight you screw down the clamps.
Watch your fingers when the blade slips!!!
