How to Choose a Fuel Filter for 7.3 Power-Stroke

The fuel filter you choose for your diesel engine is crucial to stopping contaminants from entering your fuel. One of the most serious contaminant is water. You want a diesel fuel filter that can separate water from the fuel because water causes the fuel to lkose its lubricating capacity and allows an increase of friction that can cause overheating. The overheating can lead to irreparable damages. Make sure that the fuel filter you buy has water separator capabilities.

Choose by type

Fuel filters come in different types that have different housings.  

A primary fuel filter is the most frequently used filter in a diesel engine. These filters are placed on the vacuum side of your fuel pump so it protects the fuel pump as well as your engine.

These filters are the first defense and they trap the larger particles of debris that might be in your fuel.

Secondary filter

The secondary filter is designed to trap the smaller particles that the primary filter does not capture. These are not water filtration or water separators. They filter out particles that are smaller than 10 microns.

Canister Fuel filters

The canister filters have a housing that is made of either plastic or metal. Inside the housing is the filter element that actually traps the debris.

Cartridge Fuel​ Filter

These are environmentally friendly because the outer shell stays in place and only the interior filter element is changed. 

Your manufacture chose the type of fuel filter to install on your vehicle. Do not change the type of fuel filter if the manufacture says that it will void your vehicle warranty. Always check your warranty to make sure that the filters you are choosing are accepted and can be used without voiding the warranty.

Filter Media 

The filter that you have purchased will have pleated filter media inside the housing. The pleating will capture the dirt and debris. This media can be made from different substances.


Cellulose is actually formulated from paper that is made from a plant based fiber and then bound together with a resin. It has large pores and is not designed to capture small or fine particles. Cellulose makes an excellent media for primary fuel filters.


Microglass is a synthetic media with small spores that allow it to capture finer particles. A microglass filter media is great for a secondary filter. The microglass filter will not have a life expectancy that is as long as the life expectancy of cellulose media filters.

Final Thoughts

The fuel filter in your vehicle is a primary protection for your engine. It helps keep the dirt and gunk that can be found in fuel from finding its way into the delicate parts of your engine. A fuel filter should be changed regularly, especially if you notice: the vehicle running rough when it is idling, having trouble accelerating, the vehicle is harder to start, the vehicle is smoking a lot, the vehicle is sluggish.
