So in my 2000 xj, I filled up the tank drove around a bit maybe used 1/4 tank. But it is reading at 1/2 tank. Its not the first time its happened, help me! What is wrong with it?

My 90 is pretty messed up. I need to try cleaning the sending unit in the tank. Pretty sure I read you can clean it with alcohol. Even messed up it let's me know when I should fill up. Except once. It was weird. was like all the gasoline burned up and my jeep just stopped! I think the gauge itself is OK because if I ground the sensor wire it goes all the way up. Hope that helps...

Yea it does help thanks! but how do I reach the sending unit?

My 90 acts screwy too. Once it gets between 1/2 and 1/4 tank,I gotta keep my ears tuned to listen for the growling.g of the fuel pump. That let's me know I'm close to running out.

Yea that's how my 95 is too! But when I fill up my '00 it sometimes doesn't read full :\

I think maybe on a 2000 you need to drop the tank to get to the pump/sending unit, but don't know for sure. Just figured out today in the thread search parentheses will search for the phrase instead of just the words. For instance "fuel gauge sending unit" The filler tube might be the hardest part. ....

Whoops, Wrong....Well it searches anyway.....
