Ok, got issues with my clocks...

Speedo is accurate working fine.
Rev counter is wandering all over the place.
Fuel gauge constantly reads full.
Temp is working fine, although flickers periodically.
MPG counter reads 50+ constantly.

I'm just hoping it's the batteries on the SI board.?

MPG counter and rev counter are SI batteries. Temp gauge may be involved too.

Fuel gauge is likely a dead sensor. The wire inside snaps and shorts out, leading to a duff reading. Only practical solution is to replace, but first make sure WHICH sensor it is in case you have two.

The fuel gauge started working before, then stopped again. I'll start with the SI batteries, I think I have a spare set...
