    My driver had a service performed at a shop in Effingham, Il yesterday. This morning he calls me from Greencastle PA and tells me he has a couple of cylinders missing. We go through the service invoice and I figured out they put a 50 micron filter (Balwin PF7755) in his Davco unit instead if the 10 micron (FS19729) it is supposed to have. The Davco unit is the ONLY fuel filter on this truck. This truck has less than 200,000 on reman Cummins injectors and 890,000 total miles. I think the wrong filter brought on the miss.

    Go to Walmart and buy 2-3 gallons of 2-cycle motor oil. Add it to the fuel at a rate of 1 oz. per gallon of fuel. It may help. Keep doing that even after the skip is fixed.

    Just got the call from the Freightliner dealer. The #3 injector is the culprit. They are sure it is just one injector. Time will tell.

    I get so tired of people that put in the wrong fuel filters. The FILTERS EVEN SAY, 50 MICRON FOR USE IN DUAL systems only! Not a primary system. The driver should have caught that and went back there before he left. The filter is even a different color!
