I didn't use the tank that came with it because I wanted a larger one. I installed a Tettra
14 oz. where about 1/2 of it sticks out of the forward compartment into the center compartment.
I didn't want it too far back and end up having fuel draw problems. The Tettra is not very big
around so it fit very easily into the space. My SuperTigre Bluehead was blueprinted and ported
by George Aldrich years ago when I first got it and it uses a little more fuel than the average
SuperTigre so I wanted a little larger tank.
Be sure to check that bellcrank every now and then as it looks like an accident waiting to happen
to me.

Good luck
