New E300 owner with questions.

I picked up a 1995 model E300 for what I think was a good deal the other day. I'm going to try and fix it up best I can. I have never owned a Mercedes before. I was wondering what I should address on this car if anything? Also had a few issues I could use some advice on: (I'm going to order a Bentley manual, I just need to resolve these issues asap).

Does the car have an electric fuel pump to supplement the IP or does the IP act as the fuel pump?

The temperature gauge will start out normal but then jump all the way to 120C as if it is getting a poor signal. Where is the temp sensor located so that I can make sure it has a clean connection? Or will this require that I replace the gauge?

It leaks a lot of diesel which makes it hard to start if it has been sitting. From what it looks like I will have to remove the intake manifold to get to the fuel tubes. Are there O-rings or something in there? VW fuel pipes don't have O-rings but I'm assuming this car does or it wouldn't leak so much. Any idea where I can find these parts?

The factory radio requires an anti-theft key to be entered and I do not have the owner's manual. Can the dealer supply this key if I give them the VIN?

The tachometer doesn't work. How do I verify it is hooked up correctly?

The vinyl in the interior is coming apart in several areas. Is there any type of glue that is recommended to put it back together?

Also, If anyone has a website that sells little odds and ends parts for a good price it would be appreciated. Thanks all.

Thanks for the info.

The wire harness looks to be in good condition. I can't see any cracks on it so far, I will spray everything with cleaner and look closer (after I disconnect the battery of course).

The temperature gauge can be fixed by punching the dash, that makes me think there is a broken spring in it that defaults to hot. Is there also a temperature warning light that will come on if it starts to overheat? I don't drive the car hard and don't need to know the exact temp, I just need to know when it is overheating.

The same can be said for the oil pressure, I see that it stays at 3 with the car turned on, this likely is not correct either.

The ABS light was on when I got it, now it is off and the SRS light is on. So I'm not ruling out the harness just yet.

Can the OVP relay be tested to verify it is working correctly versus replacing it? I have read that the connections can develop cracks that can be re-soldiered.

The car has 260k miles on it. Do you recommend changing the tranny fluid and filter for good measure or leave it alone?

I'm also looking for a good source to pick up odds and ends for this car. For instance, the chrome trim that goes on the passenger front door and a power window switch for the same.

After realizing all the parts I need to buy I'm starting to think I paid too much for this car at $1400. Opinions? It does ride better than any other car I have ever owned.
