Ford Bronco Fuel Level Sending Unit

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.

  • How You Can Keep Your Ford Bronco Fuel Level Sending Unit in Good Shape 27 February 2013

    When traveling, you need your gauges to know how fast you are going, if your car is going to overheat, and if you are running out of fuel. After all, you wouldn't want any accidents or problems to happen to you suddenly, right? To some, the fuel gauge is insignificant but it tells you when you need to re-fuel. You wouldn't want to end up somewhere without gas in the tank, now, would you? To keep your fuel gauge working, you must regularly check your fuel level sending unit, the primary part responsible for your fuel gauge's operation. Here are some tips to keep your fuel sending unit working:


    Check your connections

    The fuel sending unit on a car sends readings to the fuel gauge through wires. The fuel gauge is a purely electrical part, and is constantly in danger of being grounded or having shorted wires. If these wires fail, there is no way for the fuel sending unit to tell the gauge what is wrong with the gas tank. To make sure that the fuel sending unit and the fuel gauge is working perfectly, check your wires to make sure that there are no grounded or shorted wires.


    Make sure that your floater is working

    A fuel sending unit informs you that your car's fuel tank is full by using floaters. These are found inside the fuel tank, and they rise and fall along with the level of fuel. The needle of the fuel gauge rises and falls along with the floater and tells you whether you already need to make a gas stop or not yet. Always check your sending unit for signs that your floater is not working properly. If it is having problems, you can have it replaced.


    Take note of your 'ohm'

    'Ohm' is an electrical term used to describe the level of electric resistance in a car. If you are going to change your fuel sending unit, make sure it is compatible with your fuel gauge in terms of ohms. You should have no problems if your part arrives directly from the factory. But if you are on your own, and is replacing both your gauge and your fuel unit, you should take note of this.
