My 2002 Buick Park Avenue fuel gauge seems to like the full position although at times it does move to where I think the correct location may be.
I had the fuel sender/pump assembly in the gas tank replaced but the problem still exists.
Sometimes, when I start the car, the gauge appears to be accurate but then it creeps up to the full mark and stays there. Occasionally it will return to a reading that seems to be a little too high for the amount I think is left. I’m using the mileage since last fill up and the amount of gallons used since last fill up as an estimate of the gas left in the tank.
I suspect there may be an electrical ground problem between the sender unit and the fuel gauge but I have no clue where to begin. I'm open to bypassing the signal from the sender in the tank to the fuel gauge except I have no idea how to do that.
I have no wiring diagrams available.

Here is a photo of my sender/pump unit. The latest info on my problem: The Electronic trip odometer shows 177.2 miles. The Electronic fuel useage is 10.7 gallons used. The fuel gauge varies between 1/2 and 3/4 full right now.
