Direct-fit O-ring seal for the in-tank fuel pump and sender unit on F20, F30, F80 and F87 BMWs. Fixes fuel odour, vapour leaks and lid seepage - common on M135i, M2, M3 and M4 with high-mileage or modified fuel systems.

• Exact OEM-spec replacement for part number 16117428463
• Fits pre-LCI and LCI F-series without modification
• No guesswork: drops straight in during pump or sender service
• Not a stage 1 or stage 2 mod - but essential for leak-free fast-road or track-day reliability
