Fuel gauge not reading properly

[drjpb]

I have a 1982 GS110G with 35,000 + miles. My fuel gauge has always read the right amount of fuel. A few days ago I filled my tank and it read 3/4 of a tank. So now the tank reads 1/4 tank less that the actual amount. Bad gauge or should I be checking something else. Any help is appreciated.

Hi,

I found this on some guy's website.

Mine kept giving me false readings on my 1000.. discovered that sometimes the float arm would let the float drag on the inside of the tankk. Drain the tank and take off the cap and turn the tank up and down and listen to see if the float moves freely. Secondly there will be two or three bent over tabs on the float housing cover. Then you will see a small brass nut that attatches to the metal strip that travels back and forth on a coil in there. You can tweek that nut and move the metal tab to do a calibration. This process may take several attempts. Use a premeasured amount everytime till it reads properly.. That should bring things back in line. Just went thru the process myself and got it reading as exact as you could ask for. If the float is dragging just hold the unit along side the tank from the outside and youll see which way you gotta tweek the float arm.
