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.

Great , fluffy pillows
Size: Queen / Standard, Color: White
They came compressed into a small roll so I was wondering how they would do. BUT they fluffed up to incredible size and comfy feel. I am impressed so far!

Pillow comfort and quality
Size: Queen / Standard, Color: White
Bought this for my husband. He is very happy with it. It is well constructed. He doesn’t like too firm or too soft. It meets those requirements. Very reasonably priced. I have bought very expensive pillows that aren’t even comfortable!

Pretty good.
Size: Queen / Standard, Color: White
Me and my fiancé have been going through a lot of pillows, trying to find the right ones. We go to this local hotel to unwind and use the whirlpool sometimes. Their pillows are immaculate. So I starting looking at “Hotel Pillows”. These are not the same as the hotel pillows, not even close tbh, but they are the best ones I’ve bought so far. They are comfy from day one. I was worried when opening the box and seeing that they had the same cover on them as others I bought before, but they were not the same. Pretty comfortable, and less neck pain than any of the other ones. My house is like the house of pillows and I am finally going to start getting rid of the old ones. Maybe we’ll find some down pillows to put on our registry, but until then, these are staying on my bed.

Absolutely Amazing!! Truly the perfect pillow!
Size: Queen / Standard, Color: White
I absolutely love these pillows. They couldn't be more perfect! I have spent years buying and throwing out pillow after pillow. I struggle with a lot of neck and upper back pain and I struggled even more trying to find the right pillow on top of spending several hundred dollars on pillows that just got tossed. If you want a great night of sleep and you want to wake up feeling refreshed and not struggling with fatigue and every day neck or back pain you absolutely MUST give these pillows a try!!! They are super easy to wash, made with great quality and have not once bothered my many allergies like most pillows do. I have not noticed any of the chemical odors moat pillows give off, easy to adjust does great with just occasional fluffing. So far has stayed fluffy for me although I did put it in the dryer a time or two as the instructions stated to help with extra fluff and also because I couldn't wait for them to air fluff when they first arrived, an Air B&B we stayed at had these and I ordered them before we even headed back home I loved them so much I had to order my own and was too impatient to wait!
