If the fuel gauge drops off when you are driving then its a sending unit problem that means you have to drop the tank and replace the float and sending unit. This is a common problem for alot of cars because of cheap gas. If you have to drop the tank check the fuel pump canster for dirt because of cheap gas. Replace the fuel pump strainer and fuel pump filter. If the car or truck has about 100,000 miles you might want to change the fuel pump at that time also just to cover your back. If you take it to a shop they will charge you at least $900 to start. But if you do it yourself it will cost you about $200 dollars maybe alittle more.
SOURCE: put in new float unit on fuel pump.gas gauge still not working
did you replaced just the float , because if the resistor that messures the level is not good you didn't do any thing you have to change the level sensor next to the pump..,Im sure that;s all the problem, you should also check the wiring next to the pumpand any connector down there

Hello. You may have a problem with the fuel sending mechanism in your gas tank or you may have a fungus in your gas tank which is causing it to show much more fuel than you actually have. Drive to an AAMCO repair shop where they will scan your car's computer for free [some auto parts stores now offer this free as well so call around]. If it is mechanical it should show up on the scan, if not you probably have the gas fungus. Some auto parts stores and dealerships now sell an expensive gas tank additive that will kill that fungus. Regards, Joe
SOURCE: fuel gauge changes the amount
The fuel sender is in the tank and is part of the fuel pump module ( all in one). the fuel sender is a rheostat and is like a dimmer switch in you home to dim lights, the higher the level of fuel the more voltage the computer sees hence the lower the fuel the lower the voltage it sees. With the age of the car this is likely the problem. But there is a part in the instrument cluster that reads this voltage and sends power to the gauge intermittently. In older cars it was called a anti slosh module. It was there because as the car went up and down a bumpy road the gauge would read erratically. the cost can be prohibitive to fix this but if you can live with it i would. If not expect to spend 600 dollars or more to trace it down and fix it.
You forgot to mention the FLOATER in your tank,To do this, you have to drop the tank but be extra careful you're working with gasoline.De-pressurised it first before you start. Oh yes, disconnect battery.!!
