Fuel Pump Lock Ring Removal Tool - BMW E-Chassis MINI

The OneFastShop Fuel Pump Lock Ring Tool is the professional solution for removing and installing the retaining rings that secure in-tank fuel pump modules and fuel level sending units on BMW E-chassis and MINI R-chassis models. The two bars stack in a plus sign so four jaws grip the lock ring at evenly spaced points, spreading the force without slipping. That eliminates the cracked rings, damaged tank flanges, and bent surrounding components that come from hammer-and-chisel methods.

CNC-bent from 304 stainless steel for rust-proof, fuel-safe durability. The two-piece design packs flat for toolbox or glovebox storage and works with any standard 3/8" drive ratchet, breaker bar, or torque wrench.

Key Features

• CNC-bent 304 stainless steel construction, rust-proof and fuel-safe
• Top and Bottom bars stack in a plus sign to grip the ring at four points
• 3/8" drive compatible with any ratchet, breaker bar, or torque wrench
• Two-piece pack-flat design for toolbox, drawer, or glovebox storage
• Works for both removal and installation
• Professional alternative to hammer-and-chisel methods
• Built for lifetime use

How to Use

1. Lay the Bottom bar across the lock ring.
2. Lay the Top bar over it at a right angle so the two form a plus sign, with the square drive holes lined up.
3. Make sure all four jaws are hooked fully onto the ring.
4. Insert a 3/8" ratchet or breaker bar through both square holes. Turn counterclockwise to remove, clockwise to install.
