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.

Worth it
Okay first night using and I’m in love. Smells amazing. I’m particular about my vanillas but this is light but strong. Doesn’t disappear right away sits on the skin nice and drifts on the air as a nice aroma. Dries down wonderfully too. I did have to use a few pumps to cover each part of my body but so worth it. It’s not greasy at all and gives a nice glow. Application was easy and I do feel moisturized. Looking for the lotion version now to layer over top it.

A GREAT OIL FOR YOUR SKIN
I JUST REVIEWED THE LOTION WHICH I LOVED AND I ALSO LOVE THIS OIL. I THOUGHT THIS WAS A LITTLE BIT PRICEY BECAUSE THE BOTTLE IS A BIT SMALL HOWEVER YOU REALLY ONLY NEED A SMALL AMOUNT AS A LITTLE GOES A LONG WAY. IT ABSORBS INTO YOUR SKIN NICELY WITHOUT FEEL OVERLY GREASY AND IT LEAVES YOUR SKIN SOFT AND SMELLING VERY NICE. THE SMELL IS LOVELY BUT IT ISN'T A REAL STRONG SMELL AND THE VANILLA ISN'T OVERLY SWEET EITHER. IT IS THE PERFECT VANILLA. IT LEAVES YOUR SKIN REFRESHED AND I LOVE IT !! IT GOES GREAT WITH THE LOTION.

Very moisturizing with a great vanilla scent
I love this body oil. Very hydrating and smells amazing. It has replaced the original Palmer’s cocoa butter, body oil for me just because I like the smell better. It leaves my skin looking glowy and feels so smooth. I smell like vanilla all day. I like the pump top. It is easier to apply. Very silky consistency

Love the smell and great for my skin
This has become a permanent part of my shower routine. I use it right after I turn the water off while I am still wet, I cover my entire body from the neck down using about 8-10 pumps. I will wrap my body in a towel and finish getting ready (brush teeth, face moisturizer and blow drying hair) and then I will gently rub the towel everywhere incase there is any excess oil after it had the time to absorb into my skin. I dont think it leaves any greasiness at all, its really lightweight. What I love most of all is the smell though. A very nice, light, sweet vanilla smell lingers on your skin until your next shower. You have to put your nose pretty close to your skin to smell it so you wont be bothering anyone who had scent sensitivities. I have been using this for almost a year now and I still keep bringing my forearm to my nose to smell my skin because I love it so much. My skin has improved so much since I started using this.

JUST BUY IT!!! Finally found what I was looking for
This is the first time I have ever written a review - THATS how good this product is!! It smells like vanilla bean ice cream, it is so deliciously sweet and fragrant. I have been searching for something that leaves a strong yet natural scent on the skin and this is it. It makes me feel like a sweet and soft ethereal fairy princess and is so so so moisturizing on the skin. My bf loves it and has pointed out multiple times how soft my skin is just from a few uses I use it right out of the shower while my skin is still a bit wet. It is lightweight enough where it dries quickly enough for me to put my pajamas on without greasy-ness. I'm at work the morning after and can still lightly smell it on myself If you're looking for a sign - this is it - JUST BUY IT!!! :)
