Have you been having challenges while fueling your gas tank? You might be wondering – Why does the gas pump keep stopping when fueling?
This problem can be frustrating, especially when you don’t know what to do. However, you are fortunate to have found the right place where the solution to this issue can be discussed thoroughly.
One of the common reasons your gas pump shuts down when refueling is a sensor attached to the gas pump tip that shuts down the pump to prevent spillage or overflow.
Further in this article, we will discuss more reasons Why does the gas pump keep stopping and how you can fix this issue.
Let’s begin!
Why Does the Gas Pump Keep Stopping?
The reason the gas pump keeps stopping is that, When your gas tank is full, the shutoff mechanism switches off the fuel pump because it would be hazardous if your car’s gas tank overflowed and spilt all over the ground. Gas overflow and spillage can cause fire outbreaks.
Whenever this occurs, you may either clear or switch the nozzles.
This can also be caused by a low level of fuel, especially if the fuel pump is incompatible with the vehicle. If that is the case, do well to go to a station that has the right pump for your vehicle.
Payments through credit or debit cards may also be why the gas pump keeps stopping. For example, if you exceed your daily spending limits, the pump may stop before time. This can be prevented by making payments with cash.

Reasons Why the Gas Pump Keep Stopping
Some other reasons that make the gas pump stop before the tank gets full are;
1. The Gas Pump Is Detecting That Your Tank Is Full and Stops Automatically
There is a device in a gas pump that knows when a gas tank is filled in order to avoid overflow and spillage. However, this may likely cause the gas pump to stop before the tank is filled.
If your fuel pump stops because of this, you will have to wait till the tank goes down a little or look for another tank.
2. You’re Not Using the Right Type of Fuel
Another reason the pump may stop automatically is when you use a fuel that is not designed for the pump.
For example, the fuel pump may stop if diesel fuel goes into a vehicle that is powered by gasoline. This helps to prevent engine damage.
3. The Gas Pump Is Experiencing a Mechanical Issue
When the fuel pump stops automatically, it may be having some mechanical issues. In this case, report the problem to the pump manufacturer or the station staff.
4. Low Fuel Levels
Another problem may be low fuel level, especially if the fuel pump is incompatible with the vehicle. In this case, go to a station that has the right pump.
5. You’re Using an Incompatible Pump
The fuel pump may also stop if you use a pump that is not appropriate or compatible with the kind of fuel your car uses.
For example, a gasoline-powered vehicle cannot use a diesel fuel pump. The pump will automatically stop to prevent engine damage.
How to Fix a Gas Pump That Keeps Stopping
The following steps will help in fixing gas pumps that Keep stopping.
- Ensure you place the nozzle in the gasoline tank properly. The pump may stop before time if it is not placed inside properly.
- The gas pump will stop before the time when the tank gets filled. Read the gas meter before you begin pumping.
- The pump may not properly work if it is dirty. Clean it with a clean rag and try again.
- The pump may need replacement if it is old or develops a fault. Reach out to a gas station in your area for help.
Why Does the Gas Pump Keep Clicking Off?
Gas pumps shut off due to various reasons. The nozzle of a gas pump is produced with a sensor on the edge that stops the flow of fuel when the fuel flows in a reverse direction.
This serves as a safety measure to prevent gas overflow and spillage. Normally, this means the tank is filled.
Meanwhile, the gas pump may instantly stop without the tank getting filled. This may give you reasons to worry, but it is mostly not a big issue.
Gas pumps stopping during fueling can be disturbing; you may even find it more troubling if you don’t know what to do.
The first thought in most people’s minds will be their vehicle is faulty or has an issue. However, this is mostly not the reason.
Even when the same issue occurs at various gas stations, there is a high possibility that nothing is wrong with your vehicle. The main cause is the pump nozzle.
The design of the pump nozzle affects the way it shuts off. If you are using the nozzle and it shuts off, this does not mean it is faulty.
It actually serves as a safety measure to prevent a fire hazard. The shutoff device is positioned at the mouth of the nozzle.
Due to its name, you may think it’s an electronic device, but it is rather a mechanical sensor.
The shutoff mechanism is a little hole connecting to a pipe near the nozzle’s tip. There should be a constant flow of air through this hole into the gas pump; else, the supply of fuel will cease.
The role of the shutoff valve is to stop the flow of fuel when the tank is filled. It stops the fuel supply because when the tank overflows, and there is spillage on the ground, it may lead to a fire outbreak.
The shutoff mechanism was designed to cut off the fuel supply only when the tank is filled, but most times, the device cuts off the supply of fuel due to others reasons.
In most cases, the hole is temporarily covered with a few fuel splashes from the fuel tank. This issue is mostly seen in small cars.
Smaller cars have shorter fuel hose that leads to gas tanks. During fueling, if the fuel hose is not long, the fuel may reach the nozzle when it splashes up in the tank.
This may require small vehicle owners to make plans to prevent the fuel nozzle from shutting off.

How to Prevent Gas Pump From Stopping?
Gas pumps can be prevented from stopping when fueling your car. This can be done by reducing the gas flow rate from the gas pump.
During fueling, try not to press the nozzle’s trigger so much. If the nozzle trigger is aligned to a particular point by a notch, reset the trigger to a lower point.
Conclusion – Why Does the Gas Pump Keep Stopping
The gas pump may stop before the tank is filled for several reasons. The gas pump is designed to stop whenever it notices a particular level of gasoline in the tank. This stops overflow and spillage.
Another reason may be a low fuel level, especially if the fuel pump is incompatible with your vehicle. In this case, look for stations with compatible pumps.
Payments through credit or debit cards may also pose some challenges. For example, if you exceed your daily spending limits, the pump may stop before time. This issue can be prevented by making payments with cash.
