My jeep fuel gauge ussually show that I have an an 1/8 of a tank of fuel, no matter how much fuel I have. But every once in a while it will show the correct fuel amount. Has anyone else had this problem? I checked the connection of the fuel tank and the are all there and tight.

I'm getting tired of going by the odometer reading to figure out my gas state. It reminds me to much of the gas mileage I'm getting

Clean the connections on the back of the gauge and clean the connections to the sending unit. It could be the sending unit itself. Hard to tell because I don't know what year it is, but some times the older Jeep sending unit in the tank goes bad. It's cheap and easy to replace.

Good luck and welcome to the site. Look around a bit.

Oh yea. I have a 92 YJ 4" Rough Country lift sitting on 33's.

OK yeah. Possibly the sending unit but do the cheap and easy stuff first. Clean the gauge contacts. Dropping the tank isn't hard if you don't have some hitch welded on back there. You can get the sending unit/fuel pump at AutoZone fairly cheap. Few screws and three hoses. Two straps hold the tank in. The bolts for the straps are in the rear of the tank.
It may even be a bad gauge but not likely. There isn't much to them.
Keep us posted.

Cool. Thanks for the info. I'll keep you posted but I will not be able to get to the tank part until I am finished with the mile long, after holidays, honey do list

I have one of those lists too. It never ends.

The contacts on my fuel gauge are clean. So I guess it's my sender? It always stops at 1/4 tank.

I can't remember what year your YJ is. Probably the sending unit is getting stuck. When you turn the key off does the gauge go to empty? If it does then the gauge is not the culprit.

 

[Xpress]

Yes it goes to empty when I turn it off. It's an 89 TBI 2.5.

I believe it was just my grounds. Last time I just wiped them off with a cotton ear swab and assumed it was cleaned

Got out some sand paper and went to town on ALL of the gauges and even the light bulb contacts (going to have to replace those with LED's... another time). Sanded everything until it was all a gleaming copper color. Threw it all back together and well what do you know. I need gas! (although I knew I couldn't have had more than 2 gallons in the tank...)
