Questions and Answers

My 1981 300D is still 'gagging' for fuel after a while on a long (~1 mile) hill. I've replaced the tank strainer (which was dirty but not clogged), the prefilter, and have a newer FM100 canister for mail filtration. I'm tending to believe it must be sucking in some air during heavy fuel use. Frankly, I've lost track of the variables I've introduced: this problem may or may not relate to the FM100 installation and/or the new (original style) primer pump installation. Earlier, the Benz would pull nicely up this same hill.

SUBMITTED NOV 19, 2007 I bought my 1985 300D back in 2004 and it has been a good, reliable daily driver. I put her in storage from Jan-Oct 2007 while I was in Alaska (on an island). Since my return, I have made a 2200 mile move and have been plagued with problems. I did put fuel stabilizer in the tank before I left, it was only 1/4 full. 1. Loss of power on highway? Fuel filter/injectors? Brief History: Car historically ran 75-80mph highway with no problems. Upon my return and a fine start, 176 miles into trip noticed a feeling of 'bogging down' like running thru mud. Could not get above 63mph, no matter what.

Hi all, Thanks in large part to Mercedes Source, I have a 1981 300D that runs quite well. Really no running problems except on one hill in my normal commute. The car starts to 'stutter' about half way up this 1+ mile incline. Like it's starving for diesel (I've replaced pre-filter and FM100 canister) or has an air leak at high load. I've tightened all the hoses. BUT, this all really started sometime after I ran B99 for 4 or 5 tanks this summer. Prior to that, the car would actually accelerate somewhat up the hill in question. I do have Viton return lines and the special lines supplied with the FM100 Stanadyne filter. My next suspects are connections/hoses (again) and tank strainer (which I have not touched yet).

I own a 1976 W116 280S that used to run perfectly well but now problem is with its carburetor. Sometimes the float chamber has to be adjusted in order to run the engine and this is happening so frequently that I need a lasting solution to the problem. Otherwise at the rate which am experiencing the problem, I might get stuck right in the middle of nowhere.
