FASS Fuel Systems Drop-In Series Diesel Fuel System 2020-2023 GM (DIFSL5P2001)
Fits: 2020-2023 Crew Cab Short Bed L5P Duramax
Part No: DIFSL5P2001 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.

Additionally, 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.
2020-2023 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.
  • Extends the life of fuel injection system components.
  • Over 99 percent free and emulsified water separation with our Extreme Water Separator technology.
  • 2 Micron absolute filtration rating.
  • 100 percent drop-In, no additional modifications needed.

I Loved It
Format: Kindle
This was my first time reading a book by Elle Alexanda, and it definitely won’t be my last! I was absolutely captivated by the Lou/Ava love story. I found Lou’s vulnerability so endearing. It was an excellent read, and I wish it were available as an audiobook. The story was a slow burn, but it kept me hooked. The flirting and banter between Lou and Ava were so entertaining. I didn’t want the story to end! Well done, Elle!

Romance with a side of Thrill
Format: Kindle
4.25 stars! I was immediately engrossed in this debut novel, with the thrilling beginning and obvious future romance between Lou and Ava. I thought the setting of the town was wonderful, full of small charm and supportive characters. The little nods towards the continuing threat to Ava’s life were good. The budding romance was great, too! I think the intimacy scenes were soft and perfect. The main reason this didn’t reach 4.5 stars for me (thus would’ve rounded it to 5 instead of down to 4), is because of the POV switches during chapters. They’re a bit jumbled in; the reader is suddenly seeing or hearing things from Lou when it started with Ava, but then it quickly switches back to Ava. It’s not my favorite way for a story to be shared. I also lost a little steam towards the middle-end, right before the big finale. I’m not sure if my other hobby distracted me or if the story hit a slow spot. It’s possible I was hoping for a little more excitement. This story had more romance than thrill.

Blood and Muscle
Format: Kindle
I had this on my shelf for a while. lG reviews were great, the cover was pretty, and it sounded really interesting. It was better than I expected! Love when that happens🥰 The story was great, the writing was good, and the characters were amazing! Ava and Lou's chemistry at first was a little charged. But as the story went and their relationship developed, it turned into something more tender and very intimate. Throw in the witness protection thing, and you have quite exciting romance. I will be reading this again!
