thank you Mattman ; you are probably right , Work was done in Denver at KW House before I bought trk. Should have been Cummins parts , not sure . smokes pretty bad ( stacks , light gray ) when I use jakes also , but was hoping to not have to pull down , and replace , pistons and liners ; $$ Just spent on the parts I mentioned about $6 K . I will do the red neck tube test I just found by Rawse and friend , ( probably unload tube of fluid , lol ), Thank you again .fat boy .
