Need location or fuel relay on 90 Benz 560 sel?

The location of the fuel relay on a 1990 Mercedes-Benz 560 SEL is in the engine compartment, on the driver's side of the vehicle, near the firewall. It is a black plastic box with a green connector and is mounted to a metal bracket. The relay is responsible for supplying power to the fuel pump, so if it is faulty, the fuel pump will not be able to operate and the engine will not start. To replace the relay, simply disconnect the electrical connector and remove the relay from the bracket. Be sure to replace it with a relay of the same type and amperage rating.
