I have a 1993 Mercedes SL500 Fuel system problem. I have no power to the two fuel pumps. I traced it to a control unit Behind the passenger seat / compartment. Can any one tell me what is the part number and name to this unit? This control unit is completely rusted. I cant find it anywhere on the web .. Please help...:) :) :) :surrender:

The pumps on your car receive power through a relay located just above the battery. I believe it has a fuse. The module behind the seat is the top controller.

It's for the hard top rear window defroster.
