Oil Pressure sending unit
So my gauge is stuck at the top out mark on my 90 4.0 XJ. I positive that it is the sending unit, it looks ancient. I don't really trust electric gauges. Would there be any issues if I just pulled the sending unit and installed a mechanical aftermarket gauge?

No. The gauge will just peg all the way out off the scale. Just get a mechanical gauge, mount it somewhere, and install the fitting where the current sending unit is. Now, if you had a post 96 XJ with OBDII, you'd have issues.
