The primary function of a fuel tank is to deliver fuel from the storage tank to the engine. It works with other numerous parts to accomplish that task. A seemingly simple task can easily be compromised when external issues affect the performance of the pump. When it comes to fuel pump, there is mechanical fuel pump and electric fuel pump.
The mechanical fuel pump uses positive displacement with a diaphragm or a plunger. The pump draws in fuel in a cyclical action, traps it, and then delivers the fuel to the engine and repeat the whole process. On the other hand, the electric fuel pump, which is found in most modern vehicles, requires higher pressure.
There are a number of issues that can cause metropolitan fuel pump failure. In this article, we are going to explore some of top causes of fuel pump failure. Let’s delve into them.
- Running low on fuel
One of the top causes of fuel pump failure is running low on fuel. When you run your car repeatedly when it is low on fuel, it can deprive the fuel pump of the cooling it requires to prevent premature wear and tear. So if you usually drive your vehicle with less fuel, you are slowly destroying your fuel tank.
- Fuel contamination
Another top cause of fuel pump failure is contamination, which is facilitated by dirt and debris entering the pump when refueling or when you use low-quality fuel. Corrosion can also bring visible contaminants into the tank.
- Clogged strainers/filters
Some of the above-mentioned contaminants will eventually clog critical components of the system, including filters, strainers, and the fuel pump itself. This blockage ultimately affects the flow of fuel, which may end up affecting the car during acceleration and other long-term impairments.
- Electrical issues
Other than the factors mentioned above, electrical issues are also among the top causes of fuel pump failure. Electrical faults can significantly contribute to fuel pump failure. Among these electrical issues are loose connectors, melted wiring and connectors and rusted connectors.
You can contact a professional electrician to come and help you identify any issue of poor electrical connections. The electrician will use a high-quality digital volt, meter/ohm to test for voltage drops and continuity.
Excessive wear
Your fuel pump can also fail due to excess wear. When it comes to this cause, there is nothing much you can do about it but to replace the worn out components of the system, or the whole system if necessary.
- Bad timing
The right amount of fuel and its timing is extremely important because they regulate the combustion of fuel and the engine’s acceleration. It is crucial to maintain exact timing every time your engine’s timing belt has been replaced or adjusted.
Final thoughts
Your vehicle’s fuel tank plays an essential role in protecting your engine. That’s why it is important to take care of it. Now that you have understood some of the top factors that can cause your fuel tank to fail, it is easy to avoid them if you want to extend your fuel pump’s lifespan.
