I've noticed there's been a lot mentioned about faulty fuel gauges on
Jeeps, but I couldn't seem to find what I was looking for in the
archives. In my '89 YJ my fuel gauge reads ¼ tank when it's about
empty and way over full when I top it off. Anybody out there seen this
before and know what needs to be fixed / replaced before I go and do
something unnecessary?
Thanks

I have seen this problem before and I have it now.

This could be either a grounding problem back to the sensor in the gas
tank, the internal gas tank levelometer or the cluster itself. However,
mine is a 93 and we are therefore cousins of a kind. I moreover suspect
the instrument cluster is hurt because of a water leak. I lost my
speedometer and my first instinct was to replace the transmission
sensor. I later disassembled the dash and found the interconnect film
was corroded and connections were open. Daisy stepping with a soldering
iron and I got that instrumentation back.

Personally, I will be replacing the cluster on my vehicule when I get
the time. When I had the battery disconnected, the meter still would
not zero. The movement is most likely hurt. It is a terrible
inconvenience, I know. However, if you are familar enough with your
vehicule's fuel economy, watching and resetting the mileage log after
refueling is a work around (for now).
