    I dont even see an injection pump someone told me that these are injectors and that a plunger inside of them is driven by the cam to build up the pop off pressure is this true

    The "fix" I witnessed involved draining the diesel from the injector pump, filling it with laquer thinner and letting it sit overnight. The next day the thinner was drained, pump reprimed with diesel, injector lines bled (fuel now getting to the injectors) and away it went. Deutz technicial said it was becoming more common with the low sulfer diesel. If a fuel additive isn't used to increase the lubricity of the fuel, the recommendation is to run a unit at least once a week to keep the rack from setting up.

    Worth a try before digging any deeper.
    If this is the case with this rig, it might be worth looking for and using non-taxed or off-road diesel, the pink stuff. Besides, why pay road taxes on fuel for something that doesn't go down the road? I don't think the off-road diesel has to conform to the low sulphur requirement like it does for road vehicles.

    We use the pink stuff.

    I think you'll find it's still low sulfer and the pink just means you don't/didn't pay the highway use tax which is why you'll be ticketed if found to have pink fuel in your highway vehicle.

    I think in this part of the country it is not the low-sulphur, the exhaust smells a little different. But for the low-sulphur fuel, do you think something like Marvel Mystery Oil added to the fuel would help some in a case like this, Duanne?
