My husband needs to replace the fuel pump in a 1987 V10. It has dual tanks. Not sure if this means it has dual pumps. I cannot find a helpful video anywhere. How do we remove the bed to replace the fuel pump? Its a 1987 V10 Chevy Silverado. We found this problem when we replaced the battery, it would turn over but not start unless we sprayed starter fluid on the carbuerator. Once he gave it gas, it would die. Help!
