I need a electric pump givin it gas at all times.i tried a regular pump,couldn't get no gas anymore goin to carb.the Pump was new as well. i had to put a air compressor hose down the tank with compressor on to give it gas at all times.l like the sound of a electric pump. Im running a 850 demon mighty carb to.they need alot of gas,so it doesn't starve for fuel.
