Can a fuel tank selector valve go bad? A few days ago, after filling up both tanks, I took my Scout for a ride. As I was driving, I switched tanks. After shortly switching the tanks, my engine sputtered to a stop and appeared to have run out of gas. Since I just filled both tanks, I thought my fuel pump had stopped working. I replaced the fuel pump. When I started the engine, it would turnover but not start. When I disconnected the fuel line at the pump there was no gas in the line. I removed the gas line connector at the selector valve and no gas. Turning the valve to both tanks and still no gas. I cleaned the tanks a few back. Any advice is appreciated.
