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.

Job done

I wanted something that matched the listed application. I had to work around some tight spaces, but that was more about the vehicle than the part. I would compare part numbers before ordering.

Happy with the fit

I needed to get the car back together without making the job more complicated. I appreciated that the part looked like the photos rather than something completely different. Everything went back together without a surprise. I would buy it again if I needed the same part.

Saved Me From a Potential Disaster!

I tried using a makeshift tool for the fuel pump lock ring and almost damaged it. Thankfully, I got this tool from OneFastShop, and it made the removal and reinstallation a breeze. The 3/8-inch drive is a great feature and provides just the right amount of torque control. Excellent product!

Heavy duty and a perfect fit. If you're doing a fuel pump job on these platforms, you need this. Used it on my 135i and again on a friend's 997 the following weekend.

Saved me hours on my E90 fuel pump job. I tried using a hammer and screwdriver on the original lock ring and nearly damaged it. This tool spins the ring off in seconds. Should have bought it from the start.
