Common Issues that Your Ford Bronco Fuel Level Sending Unit May Encounter
Traveling down a long and rough road in the middle of a thunderstorm may become complicated if your fuel runs out. What if you have to jog out in the rain to get to a gas station for some fuel? This is why you should keep your fuel level sending unit working properly. This part is responsible for letting you know that your fuel is about to run out. If it's broken, you might have to deal with gauging your fuel levels as a matter of luck. Here are some problems that your fuel sending unit may encounter:
Determining the real problem
A non-working fuel gauge is the result of two things: your fuel gauge may have failed, or your fuel sending unit's float has worn out. To find out which of the two occurred, you simply have to start the engine of your car. If your needle moves to the correct place, then both of the parts are working just fine. If the gauge doesn't work, you can check the electrical wiring of the gauge. Make sure to check the float in the sending unit if the gauge needle moves with each movement of the float while you're checking it.
Checking the ground wire
The fuel level sending unit connects to the visible fuel gauge of a car. If you find that your fuel gauge is no longer giving you anything that your fuel sending unit might be telling you, check its connections. The fuel gauge is more an electrical unit and it might be that your connections are fried. You should test the ground wiring of the gauge. It might need replacing if it suddenly works after a long while.
Check the floater of the sending unit
The sending unit has a float located within the fuel tank. As the fuel level goes up or down, the float moves along with it, and this is how the gauge tells you that your fuel is near empty or full. You should regularly check this part of your sending unit too. If your gauge needle is overly responsive to the float, you should check the wire connecting the sender to the fuel gauge.
