There are a few ways to test a fuel tank selector switch. One way is to use a multimeter to check for continuity between the terminals on the switch. Another way is to remove the switch and check for voltage at the terminals with a voltmeter.
Finally, you can also test the switch by manually moving it through its positions and checking that the fuel gauge moves accordingly.
- Disconnect the negative battery terminal to prevent electrical shorts
- Remove the fuel tank selector switch from the vehicle according to your model’s specifications
- Inspect the wiring harness leading to the fuel tank selector switch for any damage or loose connections
- Use a multimeter to test for continuity between the terminals on the fuel tank selector switch
- Refer to your vehicle’s service manual for specific testing procedures and values
- If there is no continuity, replace the fuel tank selector switch with a new one and reassemble the vehicle according to your model’s specifications

What Does a Fuel Tank Selector Valve Do?
A fuel tank selector valve is a device that allows the user to choose which tank they would like to draw fuel from. This is important in aircraft as it allows the pilot to select which tank will provide the best performance for the current situation. The valve itself is usually located near the engine and has a number of different settings that correspond to the different tanks.
Where is the Fuel Selector Switch?
On an aircraft with a standard fuel system, the fuel selector is usually located on the floor near the pilot’s seat. It is a lever that controls which tank the engine draws fuel from. The tanks are usually labeled left, right, and auxiliary.
What Three Positions May Be Selected on a Fuel Tank Selector Valve?
Most fuel tank selector valves have three positions: “Left”, “Off”, and “Right”. The left position allows fuel to flow from the left tank to the engine. The right position allows fuel to flow from the right tank to the engine.
The off position stops the flow of fuel from both tanks.
What are the Different Selections on a Fuel Selector Valve?
There are typically three different positions on a fuel selector valve – “On,” “Off,” and “Reserve.” The position labeled “On” is used to draw fuel from the main tank. The position labeled “Off” shuts off the flow of fuel to the engine.
The position labeled “Reserve” is used to draw fuel from a reserve tank. Some fuel selector valves may have additional positions, such as “Prime” or “Pumps On.” These positions are typically used for priming the engine’s fuel system or for operating the electric fuel pumps.

Symptoms of a Bad Fuel Tank Selector Switch
If your car starts to experience fuel tank selector switch problems, there are several symptoms that you may notice. The most common symptom is the car stalling when you try to switch between tanks. Other symptoms can include the car not starting at all, or the engine running erratically when you do manage to get it started.
If you notice any of these issues, it’s important to have the fuel tank selector switch checked out by a mechanic as soon as possible. Ignoring the problem could lead to more serious issues, such as an engine fire.
Conclusion
If your vehicle has more than one fuel tank, then it likely has a fuel tank selector switch. This switch allows you to choose which tank the fuel will come from. If the switch is not working properly, then you may have problems with your vehicle running out of fuel or getting poor fuel economy.
Fortunately, there is a way that you can test the fuel tank selector switch to see if it is working properly.
