I am scratching my head on this one. I have a fuel flow problem on my Warrior that needs my attention. I recently "inspected" the gascolator and since have not had any fuel flowing into it for the electric fuel pump to pick up. I have plenty of fuel in both tanks. In chasing down the symptoms I removed the valve stem from the fuel selector valve. fuel does not flow from either the right or left tank. If it can't get past the Fuel Selector valve, it can't get to the gascolator. Any ideas?
