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.

  • 100 percent drop-In, no additional modifications needed.

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3

Favorite compostable plates ever!
Style: 34 Ounces, Size: 34 Count, Style: 34 Ounces, Size: 34 Count
I’ve been using the Dixie Ultra Extra Large Compostable Paper Bowls, and I can honestly say I absolutely love them! They’re sturdy, deep, and hold generous portions, perfect for everything from hearty soups and pasta to big salads or even snacks for movie night. Unlike other paper bowls, they don’t get soggy or collapse, even with hot or liquid-heavy foods. Another huge plus for me is that they’re compostable, so I can enjoy the convenience of disposables without the guilt. They’re strong, reliable, and environmentally friendly, which is a rare combo! If you’re looking for durable, eco-conscious paper bowls that can handle anything you throw in them, these are a must-have. Highly recommend!

No more washing pozole/menudo bowls for me
Style: 34 Ounces, Size: 34 Count
Very sturdy for a paper plate. Used these for pozole at a party and saved me the hassle of washing plates. Good size, bigger than you think. When serving it does get hot so use something underneath so you don’t get burned.
