If you have a diesel truck, then you should know that you will need to invest in different types of maintenance tasks and services than if you owned a gas vehicle. One of the more important services involves the replacement of the fuel filter. Find out more about the filter, why it is needed, and how to determine if you need a new one.
What Is A Diesel Fuel Filter?
Diesel trucks are obviously different from other vehicles in the fact that they use diesel fuel instead of gasoline. And diesel does contain some additional contaminants as it is not as refined as regular gasoline. This is one reason why diesel is run through a fuel filter, so all the solid materials can be removed before the fuel is placed under pressure. Additionally, the filter helps to collect any waxy formations that might develop. Diesel fuel waxing is an issue when cold temperatures cause the diesel to partially solidify. In the process, it forms into a crystalline structure that is much like a wax. This wax cannot be used as fuel and it will clog up your engine.
The fuel filter is typically located in the engine compartment where fuel can be run through the device just before it enters the engine. This means that it can be easily replaced, much like an oil filter.
Signs You Need A Fuel Filter Replacement Service
Replacement times for fuel filters can vary substantially. This is one reason why it is wise to watch out for signs that you need a new one. Most signs are the direct result of poor fuel flow due to the blockage in the filter itself. Typically, you will notice a reduction in power since the engine is not getting the fuel it needs. Reduced fuel may also create an issue where your truck will not start or it will stall quite easily.
Misfiring may become an issue, and oftentimes you will notice that your check engine light has turned on. If you have a tool that pulls up the codes and allows for evaluation, then you will see ones that indicate a lean fuel mixture. This means that the fuel and air mixture is not correct due to a low volume of fuel. Keep in mind that some codes may indicate a bad oxygen sensor, but this can be caused by a clogged fuel filter, and the code will resolve itself once the filter is replaced.
