It sounds like someone has changed things. If the vehicle has dual tanks, it should have a pump in each tank. See pic below.
If you have a pump on the frame, that was added.
When you don't get fuel and it is running, it is likely bad. I'm not sure how you would replace it, in the tank or replace the one on the frame.
Let me know.
