After a few times of seeing a tiny geyser of gasoline coming from an
otherwise ok LOOKING fuel line you may change your view of this. As I am
not in the rust belt I don't see the same kind of problems you might. I
agree that other parts fail too, in addition to the cigar tube ends
often the crappy plastic junction fails at the firewall where the fuel
line from the pump joins to the engine fuel lines. 2wd have this failure
prone brittle fuel line coupler but not Syncros.
