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.

Highly recommended
The AZURE Batana Oil Paste for Hair is a standout for anyone looking to restore and strengthen their hair naturally. It deeply nourishes the scalp, helps reduce dryness, and leaves hair noticeably softer and shinier after just a few uses. The texture is rich but manageable, and a little goes a long way. Perfect for dry, damaged, or thinning hair. this is a simple, effective addition to any hair care routine. Love it

Miracle Oil for Thicker, Healthier Hair!
I am seriously impressed with this Batana Oil Paste. It has a lovely, natural feel and has already made my hair noticeably thicker, softer, and more manageable. The fact that it's 100% pure and sustainably sourced from Honduras gives me confidence in the quality. My scalp feels nourished—a fantastic natural product!

This product did not work on my hair as it said it would
I have used this Product over three months and still haven’t seen a results, but I will order another one and see what happened with the second jar. My edges is still the same with no improvement? I was expecting a change since I read about it can grow ball spots. My edges is not completely ball but you can see a little hair there but as I use this products it did not help or change any length or anything my edges are still the same before I used the product it’s still the same after used it. I am so disappointed. Even though it didn’t help the first time I’m still gonna try it a second time just to make sure.
