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, MINI R-chassis, and select Porsche models. The two-jaw design distributes force evenly across the lock ring without slipping - eliminating 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.
