OK, I know my problem isn't due to bad gas, so I dropped my fuel tank
thanks to a reply from Jerry on the list.  The outside of the tank is in
good shape with no rust.  The inside appears to have a good deal of
buildup and some minor rust.  Has anyone had any success in
cleaning/treating with something like the POR15 system?  Or should I
just break down and get a new tank as suggested earlier?

Thanks,
Darren.
