Thx Chuck, another good suggestion. While I've been playing with this
I've also had 3 other possible float types submerged in avgas. A
shellaced wooden bead, another bead with paint, fishing bobbers (little
painted suckers with hooks (removed), also, regular cork plus another
cork painted. By the way, all of these items listed are perfect
size--will fit in 3/8 hose but too large to get stuck in brass fuel
fiitings. Both wooden beads sunk by day 3(the paint held up OK). The
fishing bobbers started to disintegrate by day 5 (I thought they were
cork but looks now like they were a closed cell foam). Both regular
corks are doing super-even the unpainted one has not absorbed any gas,
swelled or lost any buoyancy. Guess this makes sense as many older
aircraft had cork floats in the fuel systems. Anyhow, I've trimmed two
corks to the perfect size and have painted them bright orange. I will
try these out in the sight tubes and check them every day for a couple
of weeks to make sure there are no issues. Tom
