Description

FASS Fuel Systems Drop-In Series Diesel Fuel Filtration System 10-18 Ram 6.7L CumminsThe FASS Drop In Series Diesel Fuel System was carefully designed to provide the best filtration solution for the 6. 7L Cummins. 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.

The FASS Drop-In Series Diesel Fuel System was carefully designed to provide the best filtration solution for the 6.7L Cummins. 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 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.

This industry-leading water removal capabilities (3rd-party proven to exceed 99%) are reinforced by the unique design of the Extreme Water Separator (XWS). If the XWS reaches capacity, it acts as a dam, shutting down the truck and preventing major destruction of fuel system components.

FASS DROP-IN TECHNOLOGY

FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation, making the 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, the Drop-In Series Fuel Systems offer the same world-class filtration as the Titanium Signature Series and Industrial Series lines.

PERFORMANCE RADIUS CUTS

Performance Radius Cuts 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.

Looked amazing… but not built for broader shoulders
Size: Small, Color: Blue, Size: Small, Color: Blue
I got this for my husband because he’s fully leaning into his cowboy era lately (new boots, new attitude, the whole thing), and I thought this shirt would seal the deal. First impression—honestly impressed. The color is really nice and the embroidery detail looks great in person. It doesn’t feel cheap at all and definitely looks more high-end than expected. For reference, he’s about 5’6”, 140 lbs with an athletic build. The shirt almost worked—it fit well through the body and could be fully buttoned, but the shoulders were just too tight. As soon as he moved his arms, it felt restrictive, like the seams were being pushed to their limit. Which is a shame… because wow, he looked GOOD in this. And that’s coming from someone who doesn’t usually love this style. I’d say this shirt runs better for slimmer or narrower builds. If you’ve got broader shoulders or any upper body muscle, you may want to size up or skip this one. Overall, great quality and style, just not the right fit for an athletic frame.

A Western Shirt That Works as Hard as It Looks
Size: Medium, Color: Blue
A Western Shirt That Works as Hard as It Looks This men's western shirt strikes a really solid balance between style and everyday wearability. The cotton-polyester blend fabric keeps things soft and breathable without feeling too heavy, and the exquisite floral embroidery on the turn down collar adds a level of detail that makes it look far more elevated than a basic button down. Whether you're heading to a country concert, a western-themed party, or just pairing it with jeans and cowboy boots on a casual day out, it fits the moment without trying too hard. The versatility here is genuinely one of the stronger selling points. It works just as well at a rodeo or western-themed wedding as it does for everyday casual wear, and the timeless embroidered design means it won't feel dated after a season. Care is simple with machine or hand wash and hang to dry, so it's low maintenance for something that looks this put together. It also makes a thoughtful and practical gift for a husband, boyfriend, or father who appreciates a little western flair in their wardrobe. Just make sure to check the size chart carefully before ordering since sizing can vary with this style of shirt.

Well Made
Size: X-Large, Color: Navy Blue
When my husband put this shirt on, the women comment him on how he looks. I have to admit "He looks great in this attractive western shirt." The blue is a nice blue. He bought a black one, too and it is also very well made and nice looking. The sizing was perfect. It is wrinkle resistance, a great fabric thickness and comfortable. Definitely would buy him another if these ever wear out. It is a great value for the money.

Great Quality - Son loves it!
Size: Large, Color: Black
I ordered this beautiful Western shirt for my son for Christmas. He loves it so much he wears it once a week. The quality is excellent. The fabric is relatively thick, but not too thick - a nice, sturdy fabric. The embroidery is absolutely beautiful! It looks even better in person. The large fit him true to size, like all his other size large men's button up shirts. There are no loose threads or flaws in the stitching. It looks and feels expensive - well worth every penny of the $40 price. It has held up well in the wash. There has been no fading or shrinking. It is now March and it has been washed once a week since Christmas. (Please note - I don't put it in the dryer. I hang it to dry.) I highly recommend if you are looking for a fancy Western shirt.

Got more than I paid for and am so impressed!
Size: Medium, Color: Burgundy, Size: Medium, Color: Burgundy
Absolutely stunning! Great material quality and embroidery work. Every bit the same as those you'd buy at Boot Barn or other western stores for $70 to $100. I'm so impressed!! I purchased these for my son's band (4 shirts for 4 band members) and the band members love them. This saved me so much money. I'm so happy with them and plan to purchase more of these in different colors and styles. The men said they're comfortable and love wearing them.
