bumpytruck Posted October 19, 2007 Share Posted October 19, 2007 Hi I'm new here. I just purchased my first Mack. Its a 1980 DM686S TRI AXEL DUMP. I drove it home about 50 miles mostly freeway. And when I got home I noticed fuel that had leaked from what appears to be the lines at the pump. If it is indeed the pump. The throtle cable goes to it. The seller stated that he recently replaced the steering pump and pointed behind this ijection pump. I'm guessing that the lines proberly need to be snugged up after the 50 mile drive.Is this correct or should I not touch these lines? Also is the blowby that comes from the tube under the truck normal? It does not smoke at start up and feels real strong,should I be concerned? Thanks in advance Joe Quote Link to comment Share on other sites More sharing options...
