I was following up on EzLid's suggestion, of an automotive fuel pump. They're noisy, run on 12 volts, and "pulse" which, like I said, might end up being unpredictable in your application.
I've been toying with RC for more than ten years, and I really don't think you want to put a pump onboard, and the set of batteries that it's going to require, because of the humongous weight that it's going to add.
Is there any way that the engine could drive a pump?
