My 84 Westy's gas tank filler tube entry is finally about to give up the ghost as years of rusting have finally taken the toll.  The edging which "locks" the gas cap in place, are almost rusted through, and I expect will break off in the next 1-3 fill-ups.
Does anyone on the list know if anyone fabricates and sells liners (with lock-related edging) which can be slipped into the filler tube.  This would surely save me some precious $$$ if available.
