Original BMW Fuel Pump Relay for BMW 3, 5, 6, and 7 Series and M6 (1977–1988)

The Original BMW fuel pump relay switches electrical power to the electric fuel pump on 1977–1988 BMW 3, 5, 6, and 7 Series models and the M6. BMW calls the part the petrol pump relay. It replaces the earlier number 12-63-1-277-245, so it is the current BMW part for cars that came with the older relay. Production of this version began in February 1981, and BMW gives its weight as 43 g (1.52 oz). A relay lets a small control current switch the much heavier current a fuel pump draws, which keeps that load off the switch and wiring that command it. The relay is priced and sold individually.

Original BMW Parts carry a 24-month parts warranty.

The supersession explains why this relay covers cars built years before its 1981 production start. When BMW replaces an earlier number, the newer part becomes the replacement for every car that used the old one. Genuine BMW parts come as the latest version of the part being replaced. So a 1977 320i or a 1978 630CSi takes this relay as its direct replacement, just as the later 325e and M6 do.
