    BTW my air restriction guage is reading 40-50 hg. should i change the air filters. I'm an ase cert auto tech, but havent work on to many class 8 trucks, mainly class 4-5. I dont have the cummins operators manual neither the kw owners manual.
    Thanks.

    Ask heavyd. He is a good cummins wrench. You can get moderator to PM him for you. Good luck.
