There are three possibilities. The gauge could be defective. The instrument panel voltage regulator could be bad or not grounded or (most expensive) it might be the sending unit.

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.

Fule gauge dose not work right


Does it stick at about half full? I would fill up, the gauge would show full then after 60-70 mile when gauge should show less than half to a 1/4 tank the gauge still showed 1/2 tank so I'd go ahead and fill it up. Finally, I watched my mileage and when my yellow low on gas light came on I filled it half full. After a couple of weeks I filled it up and the gauge has worked every since.
