Big problem..Where is my fuel pump relay???

First off this is a 1984 190E 2.3L...

I bought this car about a month ago and it worked just fine untill I had some problems with the fuel pump. It would occasionally die but I was usually able to start it back up.

Then it died completely a few weeks after that after working flawlessly for a few hundred miles. So I looked under the car and the pump was leaking fuel. I decided to replace it.

I hooked everything up, and turned the key. It would fire but not start.

When I turn the key it wont make any noise from the fuel pump. You know, the "bzzzzzzz" noise.

So I thought it might be the fuel pump relay so I go out to check and I can't find it! The book says it should be right by the main fuse box, right next to the relay you see in the picture. I circled the place where it should be in RED.

I'm really dumbfoudned about this because I can't even find the relay and I have no idea what the problem could be. All the fuses check out fine, but then again is there even a fuel pump fuse?

Anyway, here are some pics of my engine bay, around the fuses. I also included a pic of the manual where it says the relay should be.

Any help would be greatly appreciated. Please help! Thanks.
