The WIX-33166 fuel filter filters particles of 10 microns or more
The WIX-33166 fuel filter is designed to filter particles of 10 microns or more. This is important because the diesel, gasoline, or biodiesel fuels that we put into our vehicles typically contain contaminants such as dirt, rust, scale, and water. These impurities can cause serious engine problems by plugging fuel injectors and carburetors. The impurities often originate from dirty and rusty storage tanks and, as the vehicle ages, from corrosion within the fuel system.
Fuel filters are critical for diesel engines as all diesel fuel contains some water, and removing it is crucial. The primary fuel filter for any diesel engine should be a fuel/water separator, and all WIX fuel filters for diesel engines feature Quickvent water removal capabilities. Biodiesel fuels have a solvent quality and a tendency to attract even more water, increasing the need for proper fuel/water separation.
The WIX-33166 fuel filter is an inline filter made of paper. It is sold individually and fits Ford vehicles particularly well, with customers reporting no leakage issues and praising its quality and ease of installation.
Micron ratings on filters typically range between 2 and 100, with lower numbers filtering out smaller particles. While a 2-micron filter would provide the cleanest fuel, it could also more easily block fuel flow. A 10-micron filter is recommended by engine manufacturers to help protect direct injection applications and keep the fuel system clean.

WIX-33166 is an inline fuel filter
The WIX-33166 filter has a length of 2.83 inches and an outside diameter of 3.328 inches. It is made of paper and can filter particles down to 10 microns in size. This is important as the micron size of a fuel filter can impact its performance, especially in cold weather conditions.
The choice of micron size for a fuel filter depends on various factors, including the specific application and engine design. In general, using a finer filter, such as a 2-micron filter, can provide better fuel filtration but may also lead to issues with fuel flow as it can get blocked more easily. On the other hand, a larger micron size, such as a 10 or 30-micron filter, may allow for better fuel flow but may not provide the same level of filtration.
It is recommended to use progressively finer filters as the fuel approaches the engine. For example, a combination of a 10 or 20-micron filter followed by a 2-micron filter can help ensure that the fuel is adequately filtered while also maintaining proper fuel flow.
The WIX-33166 fuel filter, with its 10-micron rating, can be an effective solution for removing contaminants from diesel fuel and helping to extend the life of the engine.

WIX-33166 is made from paper
WIX-33166 is a heavy-duty cartridge fuel filter made from paper. It is used to filter diesel fuel, which often contains contaminants such as dirt, rust, scale, and water. These impurities can cause serious engine problems if they are not filtered out.
The WIX-33166 filter is designed to remove particles as small as 10 microns from the fuel. This is important because diesel fuel can contain particles as small as 20 microns, which can cause damage to the engine. The WIX-33166 filter is made from paper, which is an effective material for trapping and removing these small particles from the fuel.
The use of paper as a filtering material has a long history. In fact, WIX Filters was founded in an old cotton mill in Gastonia, North Carolina, in 1939. The founders, Jack Wicks and Paul Crenshaw, needed an inexhaustible supply of pure white cotton thread waste for the filtering media of their new company. At the time, the region was known for its production of combed cotton yarn, which provided the perfect material for their filters.
Today, WIX Filters is known for its high-quality products, and its name has become synonymous with excellence in the industry. The WIX-33166 fuel filter is a testament to this tradition of excellence, offering superior performance and reliability for diesel engines. The paper material used in the filter is carefully selected and manufactured to ensure effective filtration and protection for engines.

WIX-33166 is easy to install
WIX-33166 is a fuel filter that can be used for gasoline, diesel, or biodiesel engines. It is an inline filter with a natural-coloured housing and a paper filter element. The WIX-33166 is designed to filter out contaminants such as dirt, rust, scale, and water from your fuel, which can cause serious engine problems if left unchecked. All diesel fuel contains some water, and removing it is crucial to avoid issues with fuel injectors and carburetors. Biodiesel fuels, in particular, tend to attract more water due to their solvent quality, increasing the need for proper fuel/water separation.
The WIX-33166 fuel filter is easy to install and can be ordered through Summit Racing. While the exact installation process may vary depending on your vehicle's specific make and model, here is a general overview of the steps involved in installing a fuel filter:
- Locate the fuel filter: The fuel filter's location can vary depending on your vehicle. It is usually found along the fuel line, which runs from the fuel tank to the engine.
- Prepare the work area: Before beginning the installation, it is important to ensure your safety and have the necessary tools and materials ready. This may include wearing protective gear, such as gloves and eye protection, and gathering tools like wrenches or screwdrivers.
- Disconnect the fuel lines: Shut off the engine and relieve the fuel system pressure. Carefully disconnect the fuel lines from the existing fuel filter. You may need to loosen clamps or disconnect quick-connect fittings. Place a container underneath to catch any spilled fuel.
- Remove the old fuel filter: Gently remove the old fuel filter from its housing or mounting bracket. Take note of how it is positioned for proper installation of the new filter.
- Prepare the new WIX-33166 fuel filter: Ensure you have the correct replacement filter, WIX-33166, which has a paper filter element that can filter particles as small as 10 microns. Inspect the new filter for any damage and ensure that it is properly sealed.
- Install the new WIX-33166 fuel filter: Position the new fuel filter in the same orientation as the old one. Securely connect the fuel lines to the new filter, ensuring all connections are tight to prevent leaks.
- Prime the new fuel filter: Before starting the engine, prime the new fuel filter according to your vehicle's specifications. This may involve manually pumping fuel through the filter or following other specific procedures.
- Start the engine and check for leaks: Once the new WIX-33166 fuel filter is installed, start the engine and inspect the fuel lines and connections for any signs of leaks. Ensure that the engine runs smoothly and that the fuel filter is secure.
- Dispose of the old fuel filter properly: Fuel filters contain residual fuel and should be disposed of responsibly at designated locations or through appropriate recycling programs.
By following these steps and consulting vehicle-specific instructions, you can easily install the WIX-33166 fuel filter to help maintain the performance and longevity of your engine. Remember to always exercise caution when working with fuel systems and refer to professional guidance or mechanic services if you have any concerns.
