  2. I found a check valve on line rated for fuel and I adapted it to work with my fuel line, it was about 50 bucks and I haven’t had any issues. The dealer wanted a couple of hundred bucks, crazy
  3. This is a hobby truck, just wanted to do everything possible to smooth it out, cause you know we have the best roads here in Jersey
  4. Can I run lower pressures in my 11x24’s to try and smooth the ride out in my DM800 tractor ?
  5. Take a hose and make a line into a jug of fuel, after priming if it runs, it’s a bad supply line from the tank possibly. Loosing its prime, look into replacing the check valve on the return line at the pump. Mine is external on the pump and I was able to buy a new check valve on line and replace it for like 50 bucks
  6. The new washer nozzles are plastic, maybe find used ones if you want to stay original.
  7. I have sandblasted my fuel tanks and now there are several spots that have appeared that look damp. The tank did not leak and these damp spots are located where weld are. Anyone coat the inside of their tanks with a sealer?
  8. What’s involved in replacing the whole vent window assembly? Does the frame and glass get installed as one unit or does the frame go in and then the glass? I see Mack sells them as a complete unit.
  9. My dimmer was a plug, but my headlights were individual wires, could be my headlight switch wires
  10. Restoring a 86 DM 800, installed the cab after paint and now have issues with lights. All the lights and blinker switch are new.Blinkers work until I turn the ignition on, roof lights are dim.I think it’s a ground issue. I have a good ground to the terminal strips on the firewall but I’m thinking because everything was disassembled for paint, I don’t have a good ground to the dash? Should I run another ground to the dash? Where should it go?
  11. Can someone tell me how all the lines for the puff valve are suppose to run on my 86 DM800? I have a 7 speed trans that has an line coming off it, does that go directly to the puff valve or to a tee mounted on the firewall that gets supplied by the parking brake valve? Any help would be appreciated
  12. My 86 DM800 has an air valve mounted in the top of the dashboard. Whoever installed this on/off valve, supplied it with air they took off the power divider switch air supply. This valve that they installed in the top of the dash next to the power divider valve has an airline that runs to a tee that is in the top of the trans just behind a breather, a blue line comes out of the tee and runs up to the top of the shifter. What does this valve do? I'm installing a new dash, and want it installed with the right valves switches etc...
