First a little background.
Purchased this vehicle back in March 2021, total of ~46000 miles, has 47600 now. It hadn't really been used all that much over the last 18 years, so was in need to some TLC.
Maintenance performed by me:
Okay, here is where it starts getting interesting. Car starts to have rough idle and eventually leads to a P0305 (misfire on cylinder 5). I replace the Crankshaft position sensor (I had a spare on hand), cleaned the throttle body, and inspected the spark plugs/wires for cylinder 5 (did replace 1 wire as it was really loose). While cleaning the throttle body, I replaced the small vacuum line that was dry rotted.
No change, same problem - rough idle and a P0305. A little more reading and research, I replace the Camshaft position sensor and all is better - she purrs like a kitten (mostly).
Now, the new stuff:
Everything seems to point to me needing to replace the fuel sending unit (again). Does that make sense, or is there something I might be missing? Obviously it will take some time to get a replacement unit in, so I suspect I'll be living with the CEL for awhile.

Now, the new stuff:
- Driving along, now have a P0106 and pending P0451. Resetting the CEL, and driving home, had pending CEL for P0106 and Lean Bank 1 and Lean Bank 2 (which I figured were due to the P0106).
- After replacing the MAP (hose looked okay). I took it for a test drive, and when I got home had a pending P0451.
