Six Typical Fuel Filter Issues of Vehicles

car mechanic, maintenance and repair servicesListed below are some of the typical vehicle issues that involve the fuel filter. A cartridge on the fuel line, the fuel filter removes particles from gas before it enters the engine. As it filters impurities from the fuel, the filter becomes increasingly dirty and eventually clogged to the point it will not be able to work properly. A compromised fuel filter will affect the general performance of the car, resulting in undesired, costly, and occasionally hazardous issues. If any of the below apply to your vehicle, call your trusted certified mechanic for an inspection right away.

Starting Disabled

When the clogging of the fuel filter is so serious that it totally blocks the flow of gas into the engine, a vehicle will basically be disabled from starting. Keep in mind that an automobile will only be able to start when fuel is provided to the engine for ignition.

Hard Starting

In circumstances where the filter is partially clogged, a small amount of fuel will be permitted to flow into the engine. However, it will be much harder to get the engine to start. An issue like this should be fixed at the earliest opportunity because it may later result in very costly problems.

Rough Idling

Rough idling can result from excessive engine combustion because of a faulty or extremely dirty filter impeding necessary fuel flow and preventing the correct fuel/air mixture.

Hesitation

A dirty fuel filter can cause engine hesitation because it only permits a small amount of fuel to flow into the engine. This issue becomes most apparent when you are trying to accelerate a vehicle from a dead stop.

Stalling

When a fuel filter is in such a poor condition that it causes engine stalling, it is due to inconsistent fuel flow. Occasionally, a sufficient amount of fuel will be provided for the normal operation of the engine. However, there will be other instances when the fuel flow is reduced so much that the car’s engine shuts down. The seriousness of the issue will depend on the kind of debris trapped by the filter, the condition and capability of the fuel pump.

Erratic Performance

A vehicle with a dirty filter will sometimes function quite well at highway speeds, but then it will hesitate while running at low speeds. This can be explained by the varying pressures provided by the fuel pump. At high speeds, the fuel pump will deliver more pressure, allowing fuel to flow through a dirty filter and into the engine, permitting the proper functioning of the car. Unfortunately, when a vehicle is operating at low speeds, pressure will not be sufficient for providing the needed volume of gas, resulting in erratic engine performance.
