What engine? If you're using a 4 stroke I think it will pull the fuel. I ran a Saito 150 on Funtana for 40 flights or so with the tank about 6" back from the engine. It actually ran fine without any pump of any kind. I didn't like the plane much but the engine ran good.

I think the 2 strokes don't pick up the fuel quite as well but I'd try it. My guess is it would work. Try it and find out. Afterall...what could happen?!?!?!
Thanks
