How do you stop gas from spilling out of filler tube near driver's door in a old pickup gas tank behind bench seat Only during right turns?

To prevent gas from spilling out of the filler tube during right turns, first check the filler neck and vent lines for blockages or damage, as these could cause pressure buildup. Ensure that the gas cap seals properly to maintain pressure balance. Additionally, inspect the fuel tank for proper mounting and alignment; an improperly positioned tank may shift during turns. If the issue persists, consider replacing the filler neck or consulting a mechanic for a thorough inspection.
