RSD501 Posted November 3, 2014 Share Posted November 3, 2014 I have a 2000 CH with a 460. It started running like the fuel filters were plugged the other afternoon. I drove it about 20 miles to drop it off and get a liner installed in the trailer. The motor was breaking up in between 1300 an 1600 rpm, when in the higher gears. the idle seemed a little rough at stoplights too. The shop called me saturday afternoon and said they went to start the truck, and it seemed to loose its prime. I went out there today, and the red fuel filter was down about an inch, and the primer didn't have any pressure. I filled the filters, cracked some lines, and eventually got the truck running. It ran pretty rough, and had no power. I tried to get it home, but I didn't think the truck would make it. Any ideas? I have never had an "electronic" mack before, and dont want to just throw parts at it.
