Next is the iFJF 12642623 Fuel Filter, a truly fantastic product. It’s a combination of a fuel filter, a fuel filter head, and a fuel indicator sensor. Basically, this product protects your engine while improving its performance.

Not only that. Thanks to the multi-layer filter media, it can filter rust, dust, and dirt before they damage your vehicle’s fuel delivery system. Also, it provides a water separation efficiency of 98%.

This is good news. As you already know, the stock filter head in your GM Duramax can leak over time. It can also become damaged as a result of hard starting and poor running conditions. By replacing your stock filter with this fuel filter, it will restore proper operation to your fuel system.

This premium fuel filter has a black electrophoresis process. Although it’s made of billet aluminum, the electrophoresis process protects it from corrosion and oxidation. It also helps to prevent dust and surface rust from finding its way into your engine. As such, your truck’s interior will look good all the time.

Apart from the black electrophoresis process, this fuel filter undergoes a second process – CNC. This process helps in preventing the black gel from falling into the filter. This may happen when fixing the black screw onto the filter. What you need to know is that the bleed screw is aluminum and not plastic.

Aluminum screws last longer than plastic screws. They are easy to remove and install. Plastic screws wear out and soften over time. As such, they are challenging to clean and screw down.

Best Duramax Fuel Filter Buying Guide 2020 

Best fuel filter buying Guide

If you want to keep your truck running its best, finding the best fuel filter for Duramax is crucial. Fuel filters for diesel engines have complex structures. They are available in different types and designs.

While the make of your vehicle, year of manufacture and model can guide you in selecting a matching fuel filter. It’s not always enough. There are several factors to consider before buying a fuel filter.

Here are four.

  • Build Quality

When shopping for a fuel filter, you want to check for build quality. This is because you need a durable and dependable product if you want to experience improved engine performance. Today, manufacturers use quality materials such as aluminum to make fuel filters.

The reason why manufacturers chose aluminum as their preferred material is due to its corrosion-resistant properties. Aluminum naturally forms a protective thin oxide layer keeping the metal from contact with the elements. This is particularly useful for fuel filters because of exposure to corroding agents.

Manufacturers may use other processes to protect the fuel filter from corrosion. One of those processes is the black electrophoresis process or anodizing. This process involves the increase of the thickness of the natural oxide layer on metal surfaces. Another method is lacquering or painting.

By creating a high-quality finish, the manufacturer strengthens the fuel filter against rust. Aluminum properties that make it an ideal material include lightweight, ductility, and impermeable. Other properties are non-magnetic, non-sparking, recyclable, and an excellent sound absorber.

It’s also essential to ensure that the internal parts are well assembled, made of high-quality materials, and well glued.

  • Fuel Filter Media

Are you worried about water contamination? Some filters help to filter both contaminants and water contamination. When the fuel has excess water, the fuel filter media restricts the flow by increasing differential pressure. This is after notifying the operator.

To ensure your vehicle improves performance-wise, select the right fuel filter media. There are several types of fuel filter media. Each media type serves a specific purpose. So, it’s essential to check your vehicle’s owner’s manual for the recommended fuel filter media.

The following are the common choices:

  1. Microglass has synthetic fibers uniform in diameter and small in size compared to the natural fibers of a cellulose filter. Recommended for use with ultra-low sulfur diesel, biofuels, and ethanol-blended gasoline
  2. Cellulose – made with a plant-based fiber material bound by resin, it helps in the removal of particulate only. They are not suitable for fine filtration. Best for use with diesel, ultra-low sulfur diesel, and gasoline fuel.
  3. Monitor filters – helps in the detection of phase separation especially in water and ethanol blends in gasoline
  4. Hydrosorb best for water detection and particulate removal in fuel. It also helps with absorption. This type of filter media is best for diesel, ultra-low Sulphur diesel, gasoline, and biodiesel.
  • Filter Size

If you decide to replace your vehicle’s stock filter, one thing you will realize is that not every fuel filter is suitable for your vehicle. Since they are not designed for universal use, each fuel filter has different dimensions.

They also come in different shapes. Choosing the best Duramax fuel filter that will match with your vehicle is essential. Otherwise, you will experience compatibility issues when the fuel filter does not fit in the mounting place.

To know the recommended filter size for your vehicle, check the owner’s manual or system manual for the fuel filter. Fuel filter manufacturers always make a list of vehicles that include trucks, sedans, pickups, and others. This list helps customers to know which fuel filter will fit in their vehicles.

If shopping for spin-on filters, make sure the threads match. If not sure about the thread size, cross-reference with the stock fuel filter. Also, ensure the inlet and outlet diameters of the filters (inline filters) match your vehicle’s fuel line.

  • Micron Level

What size of particulates would you want to catch? To get a general idea of particulates size, a grain of salt is 60 microns. Dust mite waste is 20 microns; pollen grain is 15 microns, fine sand is 250 microns while silt is 44 microns.

When shopping for fuel filters, we recommend 5 microns or less. This is because the lower the micron rating on a filter, the better it will be at filtering out particulate from your fuel system. This ensures protection for your engine.

There is an issue with choosing a filter with 5 microns and below. While it will filter out even the smallest particulate, the more particulate it catches. This gradually slows down your flow rate. It also shortens the lifespan of your filter.

To know if you have dirt and other particulates in your fuel, get a sample through the pump and inspect it. Have you seen any suspended particles? If yes, it’s contaminated. Water contamination may occur too.

This may disrupt your flow rate and may require you to replace your filter frequently. So, if you are replacing your fuel filter frequently, have a professional test your fuel for water contamination.

What you need to know is that every filter has a particular date limitation. Check the date limitation on the product before buying.

FAQs About Best Fuel Filter

What are the symptoms of a dirty fuel filter?

Signs of a dirty fuel filter are loss of engine power, random engine misfire and engine stalling under strain. If your engine is losing power when going up a hill or during hard acceleration, the reason is a dirty fuel filter.

How often should I change the fuel filter in a diesel truck?

If you are driving a diesel truck, experts recommend that you replace the fuel filter after every 10,000 to 25,000 miles. Other factors that determine the replacement time of your fuel filter include driving conditions and the type of vehicle.

Why should I change a fuel filter?

Changing your fuel filter helps to ensure your vehicle is trouble-free. It also helps to maximize the life of your vehicle’s engine. If you notice a decrease in flow rate, buy a new fuel filter.

Which pore size is best for my vehicle?

Experts recommend a rating of 5 to 10 micron. This has the capability of filtering particulates such as dirt, rust, and water. If you choose a smaller pore size, you will introduce unnecessary restriction to the fuel delivery system.

Final Thoughts

If you want your vehicle to have trouble-free performance, you should always replace the stock fuel filter with the best Duramax fuel filter. Monitor the quality of fuel and refuel at reliable gas stations. This helps to ensure that the fuel going into your vehicle is free of particulate or impurities.

By following this simple maintenance routine, you will save money and time.
