First off, the bulb IS installed in the proper direction !! lol The old line and bulb didn't pump-up either. When I got the motor it had clear lines from the tank to the engine-mounted fuel pump. When I squeezed the bulb, gas traveled toward the fuel pump. When I let off the bulb, the fuel ran back down the line toward the tank. With the glass bowl on the bottom of the pump, I could tell that eventially it would fill.<br />The motor has a real lack of power at mid-top end, I am trying to determine if the fuel pump could be the culprit ?? How can I test it ? It pumps gas when I disconnect the hose.<br /><br />Any advice ?????
