Fuel Gauge not working

[rdkng88]

My fuel gauge only registers 3/4 of a tank when full this just started after sitting it goes to 1/2 full. While driving I get readings all over but never goes to empty has anyone had this problem.

Run a new ground from gage directly to fuel tank sensor. deSanford

rdkng88....Every so often, the Centroid sending units will go bonkers on these things. Centroid claims it's caused by algae. I adjusted mine when it was new so the gauge would read more accurately. About five years later, mine went wild. I readjusted it and it has been fine ever since. If you need to know how to adjust the unit, send me a PM and I'll give you the info.
