Havent heard of many problems on stock cummins'

and we have the airdog 150 with a 2 micron fuel filter on there...

should i just send the injectors to F1 Diesel to have em checked/fixed?

 

After All This I would have your injectors checked, and run two 2 micron filters if thats the case! Your Symptoms seem lead towards injector issues

 

Well i pulled the head yesterday and found 2 melted pistons again...
1 and 6
