Fuel pump
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.
