Common Repair Uses

• Replacing a rusted or leaking fuel tank on Chevrolet and GMC trucks and vans
• Restoring proper fuel storage on 20-gallon tank applications
• Addressing fuel odor caused by tank corrosion or damage
• Repairing a tank that no longer seals correctly at the lock ring opening
• Returning a classic C/K, R, or V series vehicle to service with the correct tank size

Installation Notes and Tips

Verify the vehicle’s tank size and configuration before installation, especially on 1987-1991 Chevrolet and GMC applications where 20-gallon tank notes apply. Transfer or source the sending unit, mounting straps, and filler neck separately if your vehicle requires them, since they are not included with this tank. Confirm the lock ring and O-ring are seated correctly during assembly to help maintain a proper seal.
