While not infallible, Tony Bingelis' books are certainly invaluable,
and they cover this in detail, although the resin information is out
of date. Me, I'd use Vinylester resin for this application,
particularly if you ever plan on using MoGas.

The Glasair manuals have an excellent series of drawings with detailed
instructions for the tanks, fuel lines, and the small tank with the
"flop tube" behind the firewall and they do use Vinylester Resin..


"Sportplane Construction Techniques" covers this topic, and you can

Avgas is pretty tame stuff compared to mogas.

Imagine my surprise when I tried to melt out a styrofoam (ok, expanded
polystyrene) with 100LL. It just SAT there!

But a cup of mogas ate through 5 inches of foam in a matter of seconds.
