Hi

eurotec :

The fuel pump relay on your car is located behind the battery.

N16/4 in the picture is your fuel pump relay.

eurotec :

There should be two relays back there that look the same. The fuel pump relay will usually say "Kickdown" on it and the a/c relay will usually say "Klima" on it. There is no fuse for the relay.

Customer:

I went to mercedes dealer yesterday and the only fuel pump relays they shoe stop in 1989 models.

eurotec :

In 1990 the fuel pump relay was incorporated into the MAS relay. It will also be behind the battery but may look different. I'll attach a picture of the MAS relay and the fuel pump relay.

That's your MAS relay. If you have that relay you will not have a separate fuel pump relay.
