<VV>Flare fittings

> >> I never use anything in fuel line fittings.

Thought the flare on the end of the fuel line was what seals, the nuts are 
just to hold the flare against the ridge on the inside and there should 
never be any gas on the threads to seal (said "should" not "is"). I run 
into the same thing with O-ring fittings (getting common on cars). The bolt 
just holds the assembly together and if the O-ring fails, no amount of 
tightening will help.

OTOH I have seen seeping fuel lines seal with "one more nudge" of the wench 
but just means that an obstruction that should not have been there in the 
first place was overpowered.
