Is it time to update and optimize your Duramax's performance? Unleash the full potential of your 6.6L Duramax by upgrading to a FASS Fuel System. These pumps are available in multiple optimized flow rates to match everything from stock trucks to higher-demand builds. You're looking at a premium, complete fuel system upgrade designed to replace your factory lift pump and completely transform how your diesel delivers fuel.

These systems are designed to address common Cummins fuel issues, such as inconsistent fuel pressure, air intrusion, and inadequate filtration, which can affect pump performance and long-term reliability. Whether you're running a stock setup or have turned up the fuel, upgrading to a FASS system means cleaner fuel, more consistent pressure, and added confidence every time you get into the throttle.

Which Flow Rate should you choose?

When upgrading your fuel system, choosing the right GPH (gallons per hour) rating isn't about picking the highest number; it's about matching your pump to your truck's real-world demands. A FASS aftermarket fuel system doesn't just supply fuel; it improves filtration, removes air/vapor, and ensures your injection system gets consistent, reliable pressure. But choosing between 100, 165, 250, and 290 GPH? That's where a lot of people get stuck.

100 GPH: Stock Reliability Upgrade (Stock-600 HP)
  • Perfect for stock trucks or mild setups. If you want to eliminate factory fuel issues and improve reliability without overbuilding your system, this is the ideal choice.
165 GPH: Daily Driver + Towing Sweet Spot (600-1000 HP)
  • Best for trucks with some tuning or regularly towing. This is the most popular option for owners who want extra fuel capacity without going overkill.
250 GPH: Performance Builds (1000-1200 HP)
  • Designed for higher horsepower setups with increased fuel demand. Ideal for trucks running upgraded injectors or pushing harder under load.
290 GPH: Maximum Fuel Delivery (1200-1500 HP)
  • Built for high-performance or future-proof builds. If you’re planning big power or want maximum fuel supply with room to grow, this is the top-tier option.

FASS Fuel Systems engineered the Titanium Series diesel fuel lift pump to be the top-performing, longest-lasting, and most reliable aftermarket filtration system in the diesel industry. The Titanium Series lift pump is capable of supporting your GM Duramax 6.6L diesel engine with enough fuel for multiple fueling system upgrades. A Titanium Series lift pump also offers advanced filtration that helps protect your Duramax's injection system, effectively extending the life of your Injection Pump and Injectors. These benefits include a 2-micron filtration rating, a built-in water-separation filter, and FASS Fuel Systems' patented air/vapor removal process. Duramax diesel engines are known for injector failures; several factors can cause them, and FASS Filtration Systems is designed to eliminate those that are fuel-related.

  • FASS Whisper Technology (FWT) was developed by the engineering team at FASS Fuel Systems to reduce the noise generated by aftermarket diesel lift pumps for fuel and air separation. By using radius cuts, tighter tolerances on all gears, and a high-quality, military-specification coating over the aluminum base, FASS Fuel Systems developed the quietest fuel-air separation system on the market.
  • Performance Radius Cuts (PRC) are an advanced machining technique used to improve fuel flow through the diesel lift pump by creating smooth, flowing cuts in the aluminum housing. This prevents the reintroduction of air and vapor into the fuel and also prevents stagnant fuel pockets from forming in the corner of a 90-degree bend. FASS Fuel Systems Titanium Series Diesel Fuel Pumps are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts; lesser competitors commonly use T-Bone and square 90-degree fittings that can limit fuel flow, cause restrictions, and reintroduce air back into your fuel.
  • Mass Flow Return (MFR) technology is used to continually “polish" your fuel by keeping a positive pressure on the fuel being delivered to the engine and returning the fuel that's not yet needed back to the tank after it has been passed through the filtration process, removing dirt, air, vapor, and water. This means your fuel is constantly moved and cleaned, ensuring your diesel truck always has the freshest, cleanest fuel possible.
  • Bolt-on bracket mounts are another huge benefit to the Titanium Series lift pumps. Old mounting styles required drilling or welding when mounting your new pump. This is simplified with bolt-on brackets that utilize your Chevy's bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Series lift pump takes only minutes, and all brackets are made from machined steel for superior support and strength.

You will read this book late into the night or savor it for the next Day. :)
Format: Hardcover
What an amazing writer! Such clear and concise unfolding of events entwined with Biblical signs and Prophecy. Incredibly well researched and a joy to read. This book is a joy to read and while I'm trying to savor it, I can tell I will be reading this all night and rereading again. I want to gift this to my sister because I'm so impressed but I also want it in my collection. I will probably buy this book again for this reason. Exceptionally easy to focus and surrender to what God wants to impart in this book. Thank you for your clarity and love with this book.

Revelation Bible Study
Format: Kindle
I have completed a one year bible study on Revelation in our church, then David Jeremiah came out with his book Signs. It is absolutely FABULOUS! He is such a great writer, he explains from scripture and interprets exactly what John the Apostle is seeing and puts it to print! This was a great back up to my bible study and a resource that I will use forever. Prophecy is so important and we all have questions about where we go when we die, what is happening to our world as we have known it. David Jeremiah answers all of this and more. I am not confused anymore! I now can talk about eternity to others who may wonder why they need to know the things in this book. Once you have read "Signs" you will want to tell everyone so they don't spend eternity in that dark, dark, fiery place. Everyone needs to recognize Jesus as King. If you miss out now there will be NO TURNING BACK! I'm not a fanatic but I would hate to see anyone spend eternity in that situation. God is a God of second chances. His love is real for everyone. You need to know why you need to accept Jesus as Savior now so you won't have to endure the things that are coming. And it could be here at any moment. David Jeremiah tells you why you need to be ready!

An absolutely important read.
Format: Paperback
I bought this book on a recommendation. I loved it. It is easy to read, explains itself well, and is very informative. It always gives scripture to back it up. I have read the Bible and continue to do so, but this book explains a lot of things and also refers to actual history to and current events. It was written in 1999, but proves itself to be very important in the year we live in today. I recommend this book to anyone who is a Christian, wants to be a Christian, or even people who don't know what they believe. The author of this book has made me a fan of his writings. If you decide to read this book, you won't regret it.

Important read but a little difficult to understand
Format: Hardcover
The beginning is a well written history on the background of what is happening in Revelations, how and why Revalations came about, and what will occur in the ends times. Lots of prophecy, (which I love to read about) but I am finding it difficult to understand. I am a fast reader, so maybe for someone else, who reads slowly and with intention, they may understand it better. I guess I was hoping for a little easier read and right to the point. This could be my problem and not the book! David Jeremiah is a wonderful pastor and his teachings are always relatable and easy to understand so as I write this, I think it's the reader's problem, not the writer :)
