Sounds like the worst case could be a bad fuel injection pump/bad seals in the pump that are keeping the pump from drawing enough fuel when the level drops enough that gravity stops helping. > [Original Message] > From: > To: > Date: 12/3/2001 8:59:09 AM > Subject: Rough days ahead > > Here's a new one for you brilliant people (I don't know what I'd do without > this list!) -- My '83 300D Turbo diesel begins to idle rough as the fuel > volume slips below 1/2 tank.

I had a similar, but even stranger, symptom. When fuel level was less than 1/4 tank, the engine would actually stumble, or miss, and threaten to quit.. but only when making a rapid right turn !! Left turn - no problem. I changed the cartridge fuel filter ( and its crookedly mounted gasket ) and have had no problems since. You might also renew the in-line filter too.

There is a wire screen on the fuel line coming out of the tank. If this screen is partly clogged, less fuel will be flowing to the engine as the tank empties. When I first got Mathilde, I calculated my mileage at the first fillup. At 30-33 mpg, I could go over 500 miles on a tank of fuel. Wrong! At around 450 miles the engine, at highway speeds, felt like it wasn't getting fuel. I didn't notice the idle being rough, but it probably was. I have been refueling after 400 miles ever since. A few years ago, I noticed a fuel leak around the tank. It turned out that the hose had a small split in it and had to be replaced. I took it to my mechanic. Dennis drained the tank and pulled the hose. On the end is the screen. He tried to clean it up, but it was too far gone. He didn't have a replacement so he cut it off. One of these days I'll replace it, but, for now, I watch my other filters and replace them on a regular basis. You wouldn't believe what was in that screen! Dennis pointed out flies, mosquitos, algae...it was a mess. David, you'll probably have to drain the tank and clean or replace this screen. I'd suggest you pour in a can of algaecide...algicide...stuff that kills the algae. I don't remember any brand names (Biobor??), but any truck stop should carry the stuff. Make sure you replace your other 2 filters within a week of doing this 'cuz all sorts of junk will head for the engine. If that doesn't work, get a new screen (if you want to do it properly), drain the tank and replace it. The part is cheap, $10-12 from what I remember. On the other hand, if Jim succeeds in taking the shotgun to his 240D, he might just have a used screen... Jon '81 240D 291,100 mi.

Dumb question.... Have you checked the fluid level? I had the same symptoms on my 240D last winter. The fluid level in the reservoir was down about half way. I topped it off and haven't had any problems since. Jon '81 240D 291,100 "Mathilde" ------------------------------ End of diesel-benz-digest V1 #678 *********************************
