I had been suspecting my engine driven fuel pump of being on its last legs, mostly because it had been installed for 12 years and 1,500 hrs. I asked a couple of questions here in the past weeks and got some help.
The full story is linked below if anyone wants the whole thing. It is a little long, but should cure that insomnia you've been suffering from.

The big thing that I wanted to bring to everyone's attention was what I found when I got the old pump out. The bolts that hold the bottom section were loose. I don't just mean you could put a wrench on them and turn them a bit, I mean they were backed out so you could see daylight under the wave washer. It took several turns to get the bolts just snug.
Just for reference, this is what the new one looks like.
The side in the picture is the worst, but they were all loose and they all took several turns to tighten up.
I just finished my first condition inspection on this airplane in March and didn't notice it. I had never actually put a wrench on these before, I just looked them over visually, but I am adding a step to my condition inspection checklist to put a wrench on these in the future.
