    Quick question buds, anyone know where the fuel pump relay is located in the Bavaria? (or where I could by a new one) it seems like there is no power in my fuel sending unit (from what the multimeter is telling me), and even upon giving it power it wouldn't work, so both are probably not working. So, if anyone is selling replacements or knows where I can get them please let me know :)

    There is no relay for your fuel level sending unit.

    I think there is a blog by Leslie Wong on sending unit repair. Also there are two lengths to the Bavaria sending unit so measure yours if you plan to purchase one.

    These cars use a mechanical fuel pump, which is bolted to the cylinder head between the two carbs. There is no fuse, no relay, no wiring. The sending unit is fused, but has no role in whether the car will run or not. I think you are mistaking the sending unit for an in tank pump (which your car does not have), as the sending unit is what provides the fuel gauge with the fuel level in the tank.
