There are two holes in the outer part of the jet pump housing - I think the manual refers to them as bailer passages or venture holes?? They appear to be blocked off on my jet pump, or they are supposed to be (at least one of them still is, the other fell apart when I was cleaning the pump...) are these actually doing anything on the 96 Challenger? From how they are blocked and looking over the jet pump and how it attaches, it looks like they don't really do anything that I can see...
