Would not run unless you applied manual vacuum to fuel valve so it could get gas. Then when you get it running & hook vac back to vac port it would die. Fuel valve works fine.

Why when I block off vac port(at intake) with finger it dies, it should run better,that's the same when I hook hose to it. No gas in vac hose. Valve works fine (opens &close) also when you turn engine over air blows out vac port at intake then it will start vacuuming??? Valve problem?

Why does the motor die,when vacuum,from fuel tank valve is connected to intake manifold port? Runs great with port open,but if you block it with finger it will start to die. ( when it should run better) Thanks
