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.

What is the other relay above the battery for?
Thanks

It's for the hard top rear window defroster.

Looking for the fuel pump relay on a 03 SL500

Were R129s still made in 2003?
Perhaps you should be asking in the R230 forum?
