Fuel Delivery, Filtration, and Choosing the Right Setup

Not every truck needs the same fuel solution. You use your vehicle to support your daily work and personal life demands. That’s why there’s no one-size-fits-all FASS fuel system.

When browsing our products, start with fitment first. Filter by your truck make, model, year, and engine type so you can narrow down your search to the right assortment of products. From there, think about what you demand from your pickup every day.

There are two main approaches. You can invest in a complete FASS fuel system or purchase select components to support your build goals. Some trucks already have the supporting parts in place. Others need a full fuel system overhaul. Which option is right for your truck?

What a FASS Fuel System Helps With

A fuel air separation system helps support consistent fuel delivery so your truck has the fuel supply it needs under demanding conditions. It will also filter the fuel to remove contaminants, which can improve longevity and reliability as you rack up the miles.

Diesel owners typically install a FASS fuel system when they use their truck for towing or when investing in other upgrades, such as tuning. If you want to get more out of your diesel pickup, a FASS fuel system can help by:

  • Promoting stable fuel delivery
  • Filtering out contaminants and water
  • Giving your engine an adequate fuel supply

The most important thing is to choose a quality lift pump and filtration setup that’s designed for your pickup.

Choosing by Truck Platform

When shopping for diesel truck upgrades, fitment needs to be your number-one priority. Cummins, Duramax, and Powerstroke trucks all have different fuel system layouts, installation requirements, and flow needs, so start by narrowing the product list to your exact truck platform.

For example, owners shopping for a FASS fuel system 5.9 Cummins kit often focus on towing reliability and protecting their injectors. Depending on your year and build, fuel-flow requirements can vary greatly.

A FASS fuel system 6.7 Cummins configuration may be preferable for similar reasons, especially if you use your truck for heavy hauling or hotshot work. Matching the correct flow rate and pressure support to the vehicle’s overall build is the key to getting dependable performance.

Looking for a FASS fuel system Duramax package? Pay close attention to model-year fitment and choose a kit that supports your existing modifications. Duramax trucks have different installation requirements depending on which generation you have, as well as fuel demand and intended use.

Likewise, selecting a FASS fuel system 6.0 Powerstroke kit means paying attention to fitment and supporting components. Consider any current upgrades your truck is equipped with, along with any additions you may want to make in the future.
