Duramax FASS Fuel FAQs

What are FASS Performance Radius Cuts?

FASS Performance Radius Cuts are designed to increase the efficiency of the pump, creating smooth flowing cuts within the aluminum housing, to prevent turbulence in the liquid fuel and the reintroduction of air and vapor back into the fuel supply flow of fuel through the filtration process. This technology ensures that air and vapor are separated from the fuel before it reaches your engine, providing optimal performance.

Can I install a FASS system myself?

Absolutely! The FASS Fuel System is designed with easy installation in mind. With step-by-step instructions and all necessary hardware included, installation can be completed in less than an hour with no cutting or modifications required.

How often should I change the filter on my FASS system?

The recommended interval for changing the fuel filters on your FASS system is every 15,000 miles. However, factors such as the quality of fuel used and the driving conditions can affect this interval. It's always best to check your filters regularly for any signs of contamination and change them as needed.

Conclusion

While the factory fuel filtration system will work for stock to moderate Duramax engines the FASS lift pump uses an advanced machining technique to improve flow for highly modified engines delivering super extreme HP, those 1200+ horsepower, so be sure you purchase the correct Duramax Fass system for your truck.
