Hi guys first post on here. Anyway I recently purchased a used 1999 c230 kompressor with only 73,000 miles on it. Absolutely love the car. Anyway I went to start the car today and it wouldn't turn over. It was cranking normally and everything which is good. However I noticed this gasoline smell. I popped the hood and noticed that it was leaking fuel everywhere from this area which I took a picture of. I'm just curious if anyone else has had this problem or any ideas what it could be. My only 2 guesses are either a fuel pressure regulator or fuel injector that may be cracked. Any ideas?

 

looks like an oring just sitting on top. something doesnt look right there.
