fuel tank behind seat?

[rv7charlie]

Anyone done it in a LE or XL? Looks like 5 gal could be kept in front of the aft wing attach point, which should minimize CG change vs wing tank.

Building folding wings, so it would be nice(er) if fuel wasn't a concern when folding.

Thanks for any insights.

It sure would save the build time of a custom wing tank.  I'm curious about this too since my engine came with an electric pump.  I suppose the plane will have to be finished and weighed in order to figure out if it would work.  Every W/B is different.
