Fuel Sender

Fuel Sender Assembly:

The fuel sender consists of a float (4), a wire float arm (5), a fuel level sensor (6), and a roll-over valve. The position of the float arm indicates the fuel level. The fuel level sensor contains a variable resistor which changes resistance in correspondence with the amount of fuel in the fuel tank. The PCM uses the inputs from the fuel level sensor in order to calculate the total fuel remaining in the fuel tank. This information is then sent to the fuel gauge. The Evaporative Emissions (EVAP) pipe of the fuel sender has a pressed-in roll-over valve. The roll-over valve prevents fuel from entering the evaporative emission canister if the vehicle rolls over by shutting OFF the EVAP pipe to the canister.
