Well, it wasn't any of those colors, as it was a black / dark blue (same as
the outside of the tank color). It's possible that it could have been part of
the main fuel filler hose, as I replaced that back in 1999, due to it having a
crack in it (fuel smell on fill up, and the outer cloth being wet were the
give aways). All I know, is that I could see where it went from dark to silver
(bare metal) pretty easily, and the dark area wasn't rust.

I agree, that's why I put some 2 stroke gas into the tank, as I'd rather have
a little oil burn off, than some sort of coating clog up the bottom,
especially with a full tank. I didn't use much mixed gas, just enough to buy me some
time as I didn't like leaving all that bare metal exposed to any left over
moisture from rinsing the tank.

Also agreed. Seems more like a band aid, rather than a permant fix. Plus I've
seen some of that stuff turn to gel, and clog other things besides the tank
outlet. :O
