Fuel Tank Locking Ring for the fuel pump and sender unit assembly.

This ring secures the fuel pump and sender unit in the top of the fuel tank, providing the clamping force that maintains the seal between the pump unit flange and the tank aperture. Used across a wide range of Land Rover petrol and diesel models.

Remove and refit using the appropriate fuel pump removal tool to avoid cracking the ring or stripping the locking features. Replace if the ring shows cracks, corrosion, or damage that prevents correct tightening.

Frequently asked questions

What does the ESR3808 fuel tank locking ring do on a Land Rover?

The ESR3808 is the locking ring that secures the fuel pump unit into the top of the fuel tank. It threads into the tank collar, sealing the pump sender unit in place. A failed or brittle locking ring allows the pump to unseat, causing fuel leaks or pump instability.

Which Land Rovers use this fuel tank locking ring?

This ring fits a wide range: Defender (from VIN WA159807 on TDi/Td5, and all Defender 2007-2016), Discovery 1 (petrol from VIN KA053801), Discovery 2, Freelander 1, Range Rover P38 (petrol), and Range Rover L322 (diesel and petrol engines).

Is a special tool needed to remove and fit the fuel tank locking ring?

Yes. Fuel tank locking rings typically require a dedicated spanner or hook tool to unscrew without damaging the plastic locking tabs. Improvising with a drift and hammer risks cracking the ring or the tank collar.
