FASS Fuel Systems Drop-In Series Diesel Fuel System 2017-2023 GM (DIFSL5P1001)

  • Fits: 2017-2019 Crew Cab Short Bed L5P Duramax
  • Fits: 2017-2023 Crew Cab Long Bed L5P Duramax

Part No: DIFSL5P1001 The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the L5P Duramax. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your L5P Duramax from the issues caused by fuel contamination.

Without proper fuel filtration, modern diesel injection systems are prone to excessive wear, which can cost THOUSANDS! By removing over 99 percent of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the L5P's injection system from premature failure. A

dditionally, by eliminating the contaminants mentioned above, our Drop-In Series System for the L5P Duramax 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.

Better still, this system requires ZERO tuning changes! Whether your L5P is stock or modified, our Drop-In Series Systems will not require adjusting tunes or clearing any codes. Our industry-leading water removal capabilities (3rd-party proven to exceed 99 percent) are reinforced by the unique design of our Extreme Water Separator (XWS).

If our XWS reaches capacity, it acts as a dam, shutting down your truck and 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 aluminum housing.

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.
2017-2023 L5P Duramax Drop-In Series System Features:

  • The only drop-in L5P filtration system that retains full functionality of the water-in-fuel sensor!
  • The only drop-in L5P filtration system with air separation!
  • Increases lubricity of the fuel by up to 10 percent by removing entrained air and air vapor.

Be ready to question everything and everyone…
Format: Kindle
We Used to Live Here definitely nails the creeping sense of dread and paranoia throughout the story. I constantly questioned whether Eve was truly unraveling or if she was the only person actually sensing danger, and the added news articles, interviews, and scientific discussions throughout the book made the atmosphere even more unsettling. I also connected with Eve’s struggles surrounding anxiety, people-pleasing, and past religious experiences, which added an emotional layer to the horror for me. That said, the pacing felt super uneven. Most of the story takes place over only a couple of days, but it dragged at times and honestly felt like it would work better as a movie than a book. Things finally picked up around the 70% mark, but the ending left me wanting much more explanation and payoff than we as the readers received. Overall, this was an eerie, anxiety-inducing read with a fantastic atmosphere, even if the execution didn’t fully land for me.

Format: Paperback
I liked the pace, the story and the characters. Sadly I found it at the end a bit confusing. I think the book needed more edition work. Otherway, it is a recommendable book if you want horror with a bit of science fiction. Be advised you'll need to use your imagination to understand certain pasages.

Not even a good read. Pass it.
Format: Paperback
Unfortunately, this book was basically a whole lot of nothing. It was not what I was hoping for, which was on the edge of your seat scary. It was not even alittle scary. Left me with unanswered questions and confused. Sorry..I did not like this book at all.

Easy to read and fall in love with
Format: Hardcover
one of those books that feels less like a story and more like an experience. Ray Bradbury captures the magic of summer, childhood, and all the little things in life we take for granted. I loved the way it blended nostalgia with those bittersweet moments of growing up. It’s slow at times, but that’s the beauty of it — it makes you stop and notice the small details, just like the characters do. For me, it felt like stepping back into a simpler time, but with all the emotions and lessons that still matter today. It’s warm, reflective, and beautiful. A book you don’t just read — you feel.

Vintage Bradbury
Format: Hardcover
Ray Bradbury August 22nd 1922 - June 5th, 2012 When Ray Bradbury died reactions came from everywhere including from President Obama. Surprising to me, few mentioned the one of his works that meant so much to me and affected my life so deeply. While he was most known to the general public for his science fiction, I found his mostly autobiographical novel Dandelion Wine to be the most impactful. At the same time it best illustrated Bradbury’s incredible command of the language, his ability to stir the imagination, and the way in which he could open windows on life. I couldn’t count the number of times I would reread a single sentence and become overwhelmed with admiration and envy at how he used words to create images in the mind’s eye. All this was particularly on display in Dandelion Wine and its sequel, Farewell Summer. For Bradbury, it couldn’t be just water. “Nothing else would do but the pure waters which had been summoned from the lakes far away and the sweet fields of grassy dew on early morning, lifted to the open sky, carried in laundered clusters nine hundred miles, brushed with wind, electrified with high voltage, and condensed upon cool air. This water, falling, raining, gathered yet more of the heavens in its crystals. Taking something of the east wind and the west wind and the north wind and the south, the water made rain and the rain, within this hour of rituals, would be well on its way to wine.” Essentially, Dandelion Wine is the story of a summer in the life of a twelve year old boy as he comes to understand what it means to be alive. But it is also a time capsule for the year 1928 of life in a small town when everyone’s world was much smaller and more compact. There is horror, love, comedy, wonder, nostalgia, and human relations. Bradbury could find unique ways to describe them all. I first read Dandelion Wine in 1957 when I wasn’t much older than Douglas Spaulding, the central character. It helped me put life in perspective as I was leaving high school. I read it the second time in the early ‘80s when I introduced my daughter to it. Kelly and I sat on our front porch swing one warm summer evening and I read aloud to her the story of Bill Forrester and Helen Loomis. It was all I could do to finish it and when I did we both had tears streaming down our cheeks. Such was the power of imagination and Bradbury’s ability to stroke it to life using just words. I read it the third time in preparation for reading the sequel, Farewell Summer, written 55 years after Dandelion Wine. Like a fine wine, it had only gotten better with age. Appropriately, Farewell Summer was given to me by Kelly and I read it on summer’s eve 2012. It was the perfect beginning for yet another summer. In both books the ravine in Green Town, Illinois, based on Waukegan, Illinois where Bradbury grew up was a central feature. I couldn’t resist going to Googlearth to see if the ravine was real. It was. And, it is still there even after Waukegan had changed from a small town to a satellite of Chicago. I was pleased to simply find I could locate it. But when I zoomed in and highlighted the little tree symbol I found the ravine is now Ray Bradbury Park. Perfect! Dan Winters June 29, 2012
