Ray,
Got a little more information on balsa fuel tanks over on RCGROUPS, and a link to a method that I hadn't heard about before. These fellows lined their tanks with very thin aluminum foil, for an added level of protection. I don't think that would be necessary with thinned epoxy. The reason I mention thinned epoxy, is that my experiments with epoxy, using 99% Isopropyl alcohol (available at bigger drug stores) to reduce the viscosity, proved that it stays flexible for years! I had a cast sample around for at least ten years, and it was still flexible the day I threw it away!

Robert, Ray,
I've seen those cut away tanks, and actually have a spare tank on hand (thanks to Larry Renger).
What might work as well, would be to cap one of the vents in an existing tank, and use the remaining vent to feed from an external tank (ala chicken hopper style). A balloon tank would work well for this I think, and could be mounted at the CG, above or below the Pee Wee venturi. As I understand it, only the hopper section has to be on a level with the Pee Wee intake.
Darn, I gave away my LNIB Tee Dee .010 to a friends young son several years ago, along with a NIB Cox Venom, and spare glow heads for both!
The family went through a divorce shortly after, and when the father moved out of state, the son lost all interest in model airplanes.
