Exploring the Availability of FASS Fuel Systems at AutoZone

For vehicle owners, particularly those with diesel engines, the fuel system is a critical component that ensures efficient performance and longevity of the engine. One of the popular aftermarket options for enhancing a diesel engine’s fuel system is the FASS (Fuel Air Separation System). It’s designed to remove air, vapor, and other contaminants from diesel fuel, thus improving engine performance, fuel economy, and reducing maintenance costs. With the growing popularity of FASS systems, many drivers are curious about where they can purchase these systems, and specifically, if AutoZone, one of the largest automotive parts retailers, offers them.

Does AutoZone Sell FASS Fuel Systems?

AutoZone is known for its extensive inventory of automotive parts and accessories, catering to a wide range of vehicle needs. However, based on the information available, AutoZone does not list FASS fuel systems in their online catalog¹. This might be due to the specialized nature of FASS systems, which are typically sought after by diesel enthusiasts or those looking for performance upgrades rather than the average consumer.

Where Can You Find FASS Fuel Systems?

While AutoZone may not carry FASS fuel systems, they are readily available through various other outlets. FASS systems can be purchased directly from the manufacturer’s website or from authorized dealers and online retailers specializing in diesel performance parts³⁴. These specialized vendors often provide a broader range of options and more in-depth expertise regarding diesel performance upgrades.

Benefits of Installing a FASS Fuel System

Installing a FASS fuel system comes with several benefits:

  • Improved Fuel Quality: By removing contaminants such as air, dirt, and water from the fuel, the FASS system ensures that only clean fuel is delivered to the engine.
  • Enhanced Engine Performance: Clean fuel means better combustion, which can lead to increased horsepower and torque.
  • Extended Engine Life: Contaminants in fuel can cause wear and damage to the engine over time. A FASS system helps protect the engine by providing cleaner fuel.
  • Increased Fuel Economy: Efficient fuel combustion can also lead to improved fuel mileage, saving money in the long run².


While AutoZone provides a vast array of automotive parts, those looking for a FASS fuel system will need to explore other retailers. The benefits of installing a FASS system are clear for diesel engine owners who prioritize performance and engine health. It’s always recommended to purchase from reputable sources and consider professional installation to ensure the best results for your vehicle.

For those interested in upgrading their diesel fuel system, researching and investing in a FASS system could be a worthwhile endeavor to enhance the driving experience and safeguard their engine’s performance for years to come.
