Anyone else encounter this? My buddy's truck has rusty fuel lines along with brake lines and the fuel return line started leaking.
Well, I got the new lines but can't get the forward section of fuel return line off the fuel cooler fitting. GM parts is telling me I cannot get that fitting seperate but I can't see spending $200+ for a new cooler just because the fitting is rotted fast to the quick connect. I was trying to get the fitting out, but was starting to twist the cooler and don't want to disable the truck without knowing where I can quickly get the fitting.

Any info would be greatly appreciated.
TIA, Joe
