Fuel Gauge Woes

Fuel Gauge Woes
My fuel tank gauge (car is a 1998 z-28) is showing full even after driving 100 kms (pipe dream in the LS1). What could be causing this?? Bad sensor? short circuit? fried fuel sending unit?
Any ideas/help would be appreciated.
Thanks

How long has it been doing this?
After I fill mine up, the needle is to the right of FULL, then after driving about 45-50 miles, it's right at the F or just to the left of it, is this what you're talking about?
Sorry, I don't know how many miles 100 kms is, that would help better.

If you fill it up to the brim, the sesor will read full until the gas drops below the level of the sensor. There is some tank that is above the sensor and all of the gas in this area must burn before the fuel reaches the sensor, then thw fuel gauge will begin to fall.
Also, going down a hill or up a hill or conering will change the reading of the gas level. Once it has been changed it may take about 30 seconds for it to give you a real reading.
Hope this helps

Well, 100KM is roughly 60 miles. It could be a fuel level sensor going bad. Although it could be anything between it and the gage, it's typically the level sensor.
My '98 Z28 has done it for a tank or two right around 36K miles and right around 72K miles. But then it clears up. I just make sure I fill it up no later than 200mi. Haven't taken it on any roadtrips since the last instance.
