I have a 7.5 gamefisher which I can't seem to keep running. when I use the remote tank, it doesn't seem to get enough fuel.When I use the engine tank and turn on the fuel knob, gas was running out the exhaust down on the column before attempting to start it. I removed the carburetor and hooked the gas line back up from the engine tank. When I turned the fuel on, gas poured out the little rubber element pump. Should this do this, or is there something not working properly.
