I reciently had my fuel pump changed. now it seems like the gas guage is messing up. I have put a full tank of gas and within two days it goes to empty and the light comes on. I parked the car cause it happened right as I got home. suddenly the gauge went back up. what can be causing this to happen. I had the fuel pump rechecked on the connection and hoses. no problems. I don't want to be driving and not knowing exactly how much gas is in my car.
The fuel level sender located in the fuel tank is either part of the fuel pump or attached to it. The person that replaced the fuel pump did something to mess up the fuel level sensor. I would take the vehicle back to the person that replaced the fuel pump and tell them to fix it properly.
On the side of the fuel pump assembly is a float attached to a thin rod, that measures the amount of fuel in the tank. It must be getting hung up or not attached properly. You'll have to remove the assembly again to check/inspect.
Answering at the same time Bob. ;-)
