DA5231 Britpart Locking Fuel Cap Defender L663 Diesel
Fuel theft is a real concern, and the DA5231 Locking Fuel Cap from Britpart is a straightforward, effective solution for keeping your diesel topped up and tamper-free. Designed as a locking upgrade over the standard cap (superseding 202123479), this unit drops right into your existing fuel filler neck with no modifications required. It ships with two matching keys, so you have a spare on hand from day one.
This cap is confirmed for diesel models only and fits the Defender L663 (2020 onwards) as well as the Discovery 5, Discovery Sport (2015 onwards), Range Rover Velar (2017 onwards), Range Rover Evoque (2019 onwards), and Range Rover L460 (2022 onwards). Installation is as simple as swapping out the original cap — no tools, no drilling, no wiring. It is a direct fit that takes under a minute.
Britpart has been supplying Land Rover owners and workshops worldwide for decades, and DA5231 carries their standard 24-month guarantee. Whether your Rover sits on a job site, a trail head, or a busy urban street, this cap adds a meaningful layer of security without altering the look or function of your fuel system.

[FAQ]
Is this fuel cap compatible with gas models of the Defender L663?
This cap is confirmed for diesel models only. It is not suitable for gas-engined variants of the Defender L663 or any other model in its fitment range. Always verify your engine type before ordering.
What is included with DA5231?
The kit includes one locking fuel cap and two matching keys. No additional hardware or tools are required for installation, as it is a direct drop-in replacement for the standard cap referenced as 202123479.
Why choose a locking fuel cap over the standard unit?
The standard fuel cap provides no security against fuel siphoning or tampering. The DA5231 requires a key to open, making unauthorized access significantly more difficult. It is particularly useful for Rovers that are parked in public areas, on work sites, or left unattended for extended periods.
