I'm looking for the fuel pump relay on my 1980 380SE Euro
Does anyone know where it is? And how to check it? thanks..

The Fuel pump relay is at the left in the fuse box.

I found it in the trunk it is jumped and missing. also found someone jumped from fuses to red black fuel pump wire in fuse box what should I do now there is no power to red /black line without jump. is the fuse bad? do in need to replace whatever was in the trunk?
