Thanks Terry; I'll probably try that. I really wish the problem was just the hoses being disconnected!
What do you mean by the "cat" side? Both old hoses were connected to the DPFE but not connected to the EGR tube nipples.
How important is it for the *correct* hose to be on there? If I bought another hose like the one I just installed and put it on and it stayed on there, would I be causing problems if the air flow allowed by the hose was not the proper amount? At this point I don't know how to find out for sure what the correct hose and part number is.
