I have a 1987 Chevrolet Silverado with a 350 TBI and a 350 transmission. It came with dual tanks. I am almost positive that the fuel tank selector valve has gone bad. When I bought the truck 2 mths. ago, only the right tank could be used. When I switched to the left, it would die. The truck would not start the other day and I tapped on that valve and it started right up. Where can I purchase an original (or close) valve? Thanks in advance for all your help.
