DPTOOL Fuel Pump Lock Ring Removal Tool 5.2–7.6" Adjustable — 3‑Arm Hardened Steel, 1/2" Drive

DPTOOL Fuel Pump Lock Ring Removal and Reinstall Tool is a heavy-duty, adjustable three-arm wrench designed to remove and reinstall fuel pump locking rings ranging from 5.2" to 7.6" without hammering or damaging the pump assembly.

If you service fuel pumps or replace in-tank components, the locking ring can be the hardest part to handle with traditional punches and hammers. This DPTOOL unit provides a controlled, mechanical method to turn and reseat the collar, reducing the risk of damaging the pump or surrounding components. Constructed from hardened steel and built to accept a 1/2" breaker bar, it aims to simplify a common workshop task and save you time.

How does this tool make replacing a fuel pump faster and safer?

The DPTOOL unit eliminates repeated hammer strikes and improvised tools that can deform or misalign the locking ring. Its three adjustable arms apply even pressure for smooth rotation, enabling cleaner removal and more accurate reinstallation.

• Adjustable diameter 5.2"–7.6" fits many ring sizes.
• Uses a 1/2" breaker bar for controlled torque delivery.
• Three-arm design distributes force to avoid ring deformation.
• Hardened steel construction resists bending and wear.

Will this tool damage the fuel pump or tank collar?

When used as intended, the DPTOOL avoids the concentrated impact of a punch and hammer, which is the common cause of damage. The tool’s arms cradle the ring and rotate it evenly, reducing the chance of popping the ring out of its rail or nicking the pump housing.

• Non-impact operation prevents sudden jumps of the ring.
• Even torque reduces stress on the pump flange and sealing surfaces.
• Proper fit reduces slippage and accidental gouging.

Which vehicles and ring sizes will this tool work with?

This model covers locking rings whose external diameter falls between 5.2" and 7.6". It fits many domestic and import applications, but you must measure your vehicle’s ring before purchasing to confirm compatibility.

• Adjustable arms accommodate a broad range of ring diameters.
• Not suitable for rings smaller than 5.2" or larger than 7.6".
• Check your OEM service manual or measure the collar diameter before ordering.

What makes this DPTOOL product durable and service-friendly?

The tool is manufactured from high-quality steel engineered for workshop use and includes a 12-month warranty against defects. Its simple mechanical design means few wear points and easy long-term reliability when maintained properly.

• Hardened steel body resists bending and fatigue.
• Compatible with standard 1/2" breaker bars for easy leverage.
• Replace or refund offered if quality issues arise within 12 months.

Who is this for: The DPTOOL Fuel Pump Lock Ring Removal and Reinstall Tool is aimed at professional mechanics, DIY enthusiasts who perform fuel pump or in-tank work, and automotive shops that want a safer, faster alternative to hammers and punches. If you routinely encounter locking rings within the 5.2"–7.6" range and want a reusable, robust tool to speed removal and ensure precise reseating, this tool is a practical addition to your kit. Always verify your ring diameter before purchase and follow vehicle-specific service procedures when accessing fuel system components.
