Hi,

Im so glad i found this site, as it has so much helpfull info. Anyhow here is my problem, I have a 1995 e300d, it has a 606 enginge in it, and recently it developed a leak on top of the IP where the metal fuel lines attach. I bought new orings and copper washers from the dealer, and I started the job. I wish i found this site before I started, as I would have known I needed a special tool to get toi those orings. Anyhow, after getting the tool in my hands, I removed the fittings one by one, and used a magnet to pull out the copper washers, but I also removed the metal part underneath the washer. I swapped the washers, and put these parts pack in, pretty much the same way I took them out. I also replaced the gasket on the warming chamber, as I saw some fuel getting through there. I didnt replace the plastic lines, as those were replaced about 2 years ago. My problem is this, after putting everything pack, it took about 30 minutes to get the car running again ( air in the lines) After I had it started, I let it run for over an hours on my driveway, and that took some of the air out. I drove it around the block a few times, and it was very slugish, and idled very rough. The next day I started it again, and it ran abit smoother, again, drove it aroung the block, and seemed to be a bit better. Yesturday however, my wife was trying to start it in the morning to go to work, but she couldnt get it going. After 15 minutes of cranking it finally turned over. I let her take my car, and I took the hers instead. As soon as I got it out of the driveway, there was a distinctive metal banging , as if though a cylinder was hitting something metal. After a few minutes of this, I got it up to a bit higher revs' and the noise went away. I drove it to work and back, and the car was very sluggish. it was rather hard to build it up to 60mph on the highway, but I figured it was still the air in the system. When i got home, I checked the fuel lines, and they seemd alot better, there was still air in the lines, but not nearly as much as yesturday. This monring my wife took the car to work, and once she got it on the highway, the became very sluggish for about 10 minutes, where her top speed was about 45mph, after which it ran somewhat normal for the remainder of her drive to work. Any suggestions on this issue would be greatly appreciated.
