Fuel Tank Lock Ring Wrench - OTC Tools and Equipment

The OTC 6599 Fuel Tank Lock Ring Wrench is engineered to provide professional technicians with controlled and repeatable access to in-tank fuel pump and sender assemblies. This specialized tool enables the safe removal and installation of fuel tank lock rings, preventing damage to the rings, modules, or the fuel tank itself, offering a precise and reliable alternative to improvised methods for critical fuel system service.

Key Features

• Adjustable Jaw Mechanism: The universal design accommodates a wide range of late-model fuel tank lock ring diameters, fitting stamped steel or composite rings found on passenger cars, SUVs, and light trucks.
• Professional-Grade Construction: Built from durable steel, this tool is designed to withstand the significant torque required to loosen corroded or seized lock rings encountered in daily shop use.
• Positive, Non-Slip Engagement: Provides solid engagement with the lock ring, helping to prevent the wrench from slipping and reducing the risk of damage and costly rework.
• Safer Operation: Offers a cleaner and safer alternative to traditional chisels or impact methods, minimizing the chance of sparks around fuel vapors and protecting plastic fuel tanks and pump modules from damage.
• 1/2" Drive Compatibility: Works seamlessly with a standard 1/2" drive ratchet or breaker bar for enhanced leverage and strength during removal and re-torque.
