1999 E300 :mad: - PeachParts Mercedes-Benz Forum

If it is not one thing it is another. Last week I had one repair made to the E300 to replace an o-ring at the fuel prefilter that lasted only 8 months. Now I see (actually I first smelled) that the top of IP where the injector lines connect is wet from fuel. I have read something about this before and I have no idea if it is a job I should attempt or take to the dealership where I bought this heap of junk.

I am so pissed that I bouth this car. It has been by far the worst car I have ever owned. My worst GM product (my current S-10) is better than this.

No, I would not do such an evil thing to you. My E300 is something that you sell to an enemy.....like that fruitcake leader in North Korea. Hey, there is a plan. If I could sell him my E300 he would never again have funding for his missles. Two problems solved.

I think the advice was if you are going to touch one line, fix them all. That is what I did and has no leaks.

I'm convinced I've got similiar problems and would like to fix them before i get stranded then raped by the stealership. I'll do this o-ring and K-40 relay thing and probably unload the car on ebay next month.

Thanks man.

My wife's E300 is not here at the moment so I am going from memory. I believe the prefilter is in the same casting as the filter. Just above the filter there are two or three lines that enter the back side of the casting. There is another line that enters the casting at a point more towards the center of the car. This line enters the casting from the top. There is a small bolt that holds a 'fork' that retains the line to the casting.

Had I considered that fact that and 8 month old o-ring would have gone bad I could have saved myself a lot of money. One thing that you might try...when I spoke with a technician he told me that somethings when there is a fuel leak suspected (and hard to find) he has a cap for the fuel tank that he hooks up an air line and supplies low pressure (PSI???). How to do this I am not sure at the moment. Granted the K-40 relay could go bad, however, the same technician told me that he as seem only one go bad and that most problems that he has experienced are due to a leak in the fuel line. Therefore, I recommend that you first focus on the fuel line. If you just want to replace the o-rings and the not lines you should be able to buy the o-rings at a hardware store. Keep me posted on what you find.

I don't see anything resembling/smelling like a fuel leak, but since i seem to have similiar symptoms to what you went through cruising down the hwy, I ought to at least have a look at the usual suspects.

I'll try and keep you updated, PM me if I get forgetful...

One thing to keep in mind. I had no fuel anywhere and no smell, but I did have a lead and I was drawing in air. Just because there is no visible fuel does not mean that you can rule out a fuel leak. My leak at the prefilter appears to be the highest point of the fuel system. When I backed my car out of the garage the back end of the car was at the low point of the slope of the garage entrance. Because of the slode more draw was required to pull the fuel to the pump, but since I had a leaking o-ring I was puuling more air until the engine stopped.

That could happen to anyone.

If I Recall Correctly.

First time I did it was when I bought the car and the mechanic replaced the shutoff valve and it leaked like a stuck pig. I brought it back to the dealership I bought it from and they fixed it, in a nutshell. The tech said he didn't have the lines so I would have to come another day. I took out my box and basically sold them the lines. He replaced 2 leaking ones and it leaked from the other and one more then he decided to fix everything and what do you know, it worked. This was all done under my supervision. Next time I did it all on my own when I took out the manifold to make sure the GPs were not stuck and moved one of the lines. Still no leak

I left a message at the dealership to schedule service. I think I am going to fix it and sell it.

Honestly, I can't blame you. I bought my '98 e300 about 6 months ago and have had a similiar experience. I was out of commission for about a total of 4 weeks while waiting for new fuel lines and a transmission fuild/filter change after many "limp home" experiences. At the moment, my A/C is completely empty so I am preparing a total system reseal & new drier (still waiting for that to arrive).

I've always serviced my vehicles myself and I'm learning something every day with this car. I can honestly say that it is well designed car with the exception of several serious flaws as well as a few odd choices by the MB engineers. I respect your desicion to dump the car as I was horrified reading up on the spring perch and body rust issues, but I think I got lucky with mine.

You should get a pretty good price for yours with ~70K miles!
