2001 Silverado Fuel Tank Switch
Andrew’s question:
“My 2001 Silverado has two gas tanks. One works, the other just stays full of gas. What can I check to make them both work again?”
Answer:
There’s a switch that makes the tanks change from one side to the other on the dash. I haven’t seen any of those switches go bad, but I have seen a few of the relays that operate the fuel cross over valve go bad. I’d check that relay first as it’s a more common problem.
