Maybe double check your filter manifold, if you have one. They can be pretty tricky. This clip is one I did for a different forum.Thats what Petebilt guy said too. I had (deleted back about april) before and after pics of pressure guage but they say impossible. I dunno what was up but they wanted to rebuild but I wanted to try it first. Try as you might but you will never convince me otherwise unless it happens again soon. Here’s the best I can do with pic of it installed on a C15 6NZ. View attachment 704073
