Well, a fishtank pump might work out for you... how about those kits they sell for trans fluid pumps for flat towing automatic cars?
Um... You could get a drill-powered fluid pump and attach a small RC motor to it?
I hardly think the motor should be a cause for concern... there are literally 100's of options.
