Been a bit of a lurker here for some time and now find myself with a question I haven't been able to figure out.
I recently picked up a RHD 1997 Wolf 90 with the 300tdi and was looking to put in a boost gauge - my original plan was just to tee it off of the charge pressure line running to the fuel injection pump, when I was following that back I found that there was a tee just prior to the fuel injection pump that also ran to (from my cursory glance) looks like the timing cover and connects to a banjo bolt. I haven't been able to find anything in my parts manual or workshop manual relating to this - any ideas?
Unrelated question, is there ever anyone looking for military radio mounting bits? I have a bunch I pulled out that I have no interest in (pic below).
