Fuel quality is critical for optimal performance in any engine, diesels even more so. Given that fuel is not only the source of combustion, but also lubrication of injector nozzels, having water or air gaps in fuel pressure can lead to premature failure of injectors, loss of power, poor fuel economy or even catastrophic damage. The diesel we provide for our trucks is never 100% clean and clear. Condensation, worn out storage tanks, particulates and cost cutting methods by large fuel providers lead to you topping your tank with a lot more than just diesel. The 6.7L Cummins in your 2007.5-2009 Ram deserves clean filtered fuel, and you deserve a truck that runs as good as it can. FASS comes to fulfill your truck's dietary needs with their Cummins fuel filtering Diesel Drop In Series kit.
Without proper fuel filtration, modern diesel injection systems are prone to excessive wear, which can cost THOUSANDS! By removing over 99% of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the Cummins injection system from premature failure.
Additionally, by eliminating the contaminants mentioned above, the fuel filtering Drop-In Series System for the Cummins optimizes MPG (results will vary), restores horsepower, and sharpens throttle response. And if reliability, optimized MPG, restored horsepower, and a sharper throttle response isn’t enough, this system can be installed in an hour or less! This is a true plug-and-play system, requiring no cutting, wiring, or additional modifications.
With industry-leading water removal capabilities (3rd-party proven to exceed 99%) reinforced by the unique design of their Extreme Water Separator (XWS) FASS is also vigilantly protecting your truck. If your XWS reaches capacity, it acts as a dam, shutting down your truck, preventing major destruction of fuel system components.
- FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation—making our Drop-In Series Systems a true bolt-in upgrade. If you’re mechanically inclined, a Drop-In Series Fuel System can be installed in your driveway in less than an hour! But don’t let the easy installation fool you—our Drop-In Series Fuel Systems offer the same world-class filtration as our Titanium Signature Series and Industrial Series lines.
- Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth-flowing cuts within the filtration system. This prevents the reintroduction of air and vapor back into the fuel and prevents eddy currents from forming within the corner of a 90-degree sharp angle. FASS Drop-In Fuel Systems 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.
The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the Cummins. Backed by their limited lifetime warranty, the Drop-In Series Fuel System protects your 5.9L Cummins from the issues caused by fuel contamination.

2nd pair
Bought these locally for my grand-daughter. She wore them ALL the time and wore them out. She was so excited when I was able to find another pair on Amazon. She was begging me to sew them back together.

Defected Item
I bought two pair of these slippers, one for each of my children. One of the slippers on the smaller pair is defected, but alas we are past the return period. I just hate that we spent a good amount of money for what should be a quality product and it is defected. I hate for her to continue to wear them and possibly injure her foot due to the way the shoe leans.

Great quality
Size: 7-8 Toddler, Color: Moo-moo Cow
These are so cute and comfortable. My 3 yo can put them on himself and it is so cute that they light up. Fit as expected and are great quality. Even the dog hasn’t been able to tear them apart. Would buy more styles!
