I’ve been just trying to fix previous owners screw ups and it’s been a job .. I’m ready to throw in the towel if this oil pump and tube doesn’t fix it .. sick of messing with it and like I said previously no one around us is that familiar with Cummins, I’ve reached out to haggai but they are so busy they keep scheduling a month out and sound like they don’t really want to mess with it so I’m just trying to do all I can myself

so why did you buy into a used, (according to you) hodged-up pile of crap to begin with then?. That would be the bigger question... and YES, things can be done right,., and YES, it can be made into something very reliable.. but things need to be done properly for that to happen.
