Original BMW High-Pressure Fuel Pump Seal for BMW M5, M8, and M8 Gran Coupe (2018–2024)

The Original BMW high-pressure fuel pump seal closes the joint where the direct injection high-pressure pump mounts on the S63M engine in the BMW M5, M8, and M8 Gran Coupe. BMW names it Seal high-pressure pump under part number 11-12-8-071-821, and its production of this seal began in November 2017. The seal is made in Germany and sold individually as a single piece. The store title calls it a gasket, but BMW's name is more precise, and that name is the one to match when you compare parts. On any direct injection engine, the high-pressure pump raises fuel pressure well above what the tank pump supplies. The seal under the pump keeps that mounting joint closed.

Original BMW Parts carry a 24-month parts warranty.

BMW assigns this seal to the S63M engine in the F90 M5 and to the F91, F92, and F93 M8 bodies. All three M8 body styles use the same seal, so the coupe, convertible, and Gran Coupe need no different version. BMW's parts data shows no earlier or later number for 11-12-8-071-821. The current seal is the same part that has been produced since late 2017. If you are working on the pump mounting, order this seal by its BMW name so it is not confused with other seals in the fuel system.
