You can try mixing a little micro, stick in a BB and you will have your self
a float.  Make it a tear drop or round and just grind away to the size you
want.  Add a florescent pigment to the micro and it will shine if you use an
LED light or any other light.

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
