sixcow Fuel Pump Module Spanner Wrench Adjustable 33–156mm (1.3–6.15in) Black Anodized Steel CNC

Sixcow 25156 is an adjustable spanner wrench engineered to remove and install fuel pump retaining rings and silent fuel tank lids with outer diameters from 33mm to 156mm. This heavy‑duty tool is built for professional mechanics and DIYers who work on Mercedes‑Benz, BMW, Audi, Volkswagen (VW), Chrysler and other vehicles that use threaded retaining collars on their fuel pump modules. CNC machined steel, a black anodized finish, and an adjustable arm layout let the wrench engage internal and external ring ribs for secure torque transfer without damaging the tank or module.

How does the 25156 spanner wrench engage different locking rings?

The wrench features adjustable arms and interchangeable contact ends that adapt to inside and outside grips. You set the arm span with the supplied screws and washers, then lock the arms and use a 3/8" drive ratchet to apply torque safely.

• Adjustable width from 33mm to 156mm (1.3–6.15 in)
• Contact ends designed to fit common retaining ring ribs
• Works for internal and external ring profiles
• Secures with standard 12mm wrench on arm screws

Can I use this tool without risking damage to the pump module or tank?

The 25156 is designed to minimize slippage and concentrated stress by engaging multiple ribs on the retaining collar. The CNC finish and precision machining reduce wobble while the black anodize improves resistance to wear and corrosion.

• Multiple contact points for even torque distribution
• Heavy‑duty steel resists bending and deformation
• Low‑slip engagement lowers risk of marred sealing surfaces
• Use with a 3/8" ratchet for controlled torque application
