Several Causes of Diesel Engine Fuel Pump Damage

Diesel engine cars are becoming increasingly popular. New vehicles with the same type of engine frequently emerge. However, many still doubt their capabilities due to a lack of knowledge about the causes of diesel car fuel pump damage.

Generally, the fuel tank is stored at the bottom of the car, requiring a pump to circulate it. This is known as the fuel pump. This device is very important but is vulnerable to damage.

4 Causes of Diesel Car Fuel Pump Damage

A non-functioning fuel pump will certainly disrupt the fuel supply to the combustion chamber. Thus, a well-maintained fuel pump is one of the factors for smooth driving.

Fuel Pump Clogged with Dirt

The first cause of fuel pump damage is that its channel is clogged with dirt. There are many causes, such as the addition of additives for fuel acceleration, gasoline that is allowed to run low, or dirty fuel being used.

The fuel used can soak the fuel pump and leave deposits. As a result, no matter how small the dirt is, it can still cause the pump to work suboptimally, and if left unchecked, it can completely fail.

The most common indicator of dirt in the pump can be noticed when you start the car engine. The engine cannot start consistently, and when the engine speed increases, it suddenly dies.

Using Low-Quality Fuel

The dimensions of a diesel fuel pump are actually larger compared to a gasoline engine. However, its larger size also indicates that the components inside are more complex.

Inside the fuel pump engine, there are components similar to a solenoid. This part functions to regulate the fuel pressure used and then circulate it into the combustion chamber.

One of the risks of using low-quality fuel is that this component will become easily damaged. Its sulfur content will damage the component because it cannot be burned completely.

Thus, the leftover unburned sulfur will gradually settle and then clog the solenoid. This is compounded if the fuel used contains a relatively high amount of water.

Therefore, for diesel engines, it is always recommended to use high-quality fuel. The use of quality fuel in the long term is certainly an investment, as it will keep the car engine in good condition.

Water in the Fuel Tank

Water in the fuel tank is also one of the causes of fuel pump damage in diesel car engines. Water inside the tank will be sucked through the pump and ultimately cause rust.

Rusting in the fuel pump will make it deteriorate quickly. Do not let the fuel tank remain empty for too long. The trapped air in the tank will cause condensation and form water vapor.

Age of the Fuel Pump

The natural cause of fuel pump damage is the age of use. Therefore, fuel pump failures are often found in older vehicles. This is indicated by the car's sluggish performance and decreasing power.

Generally, car engines perform much better than gasoline engines, especially for long-distance travel. However, you still need to pay attention to its condition for a comfortable driving experience.

The easiest maintenance to keep the fuel pump in prime condition is to always use quality fuel. Also, avoid the habit of emptying the fuel tank for extended periods, especially if the vehicle is rarely used.
