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.

Compact 5-in-1 Trimmer for Everyday Grooming
Color: Light Black
This 5-in-1 electric trimmer is designed to simplify personal grooming by combining several functions into one small device. The interchangeable heads make it possible to switch between different tasks such as trimming the bikini line, underarms, legs, or smaller facial areas. Changing attachments is straightforward, and the design keeps the process quick without needing multiple separate tools. The trimmer feels lightweight and easy to handle, which helps with maneuvering around different areas. During use, the blades glide smoothly and tend to feel gentle on the skin, making it suitable for routine grooming. The ergonomic shape also makes it comfortable to hold for longer sessions without feeling bulky. Another practical feature is the rechargeable cordless design. After charging, the battery typically lasts through multiple grooming sessions, which reduces the need for frequent charging. Because the device is compact, it fits easily into a travel bag or gym pouch, making it convenient for trips or daily use outside the home. Cleaning and maintenance are relatively simple as well. The detachable heads can be rinsed after use, and the waterproof capability allows the trimmer to be used in the shower if preferred. This makes it easier to keep the device hygienic without much effort. For people looking for a single grooming tool that can handle multiple areas while remaining portable and easy to maintain, this trimmer offers a practical and straightforward option for everyday personal care.

Thoughtful design with multiple useful attachments
Color: Light Black
Trying this 5-in-1 trimmer for a few days made it clear that the interchangeable heads are the main highlight. Each attachment has a clear purpose, so switching between trimming areas is straightforward and doesn’t require figuring out complicated settings. The motor runs quietly and the trimming action feels consistent without snagging hair. The body of the device is lightweight and comfortable to hold, which helps when working around smaller areas that need more control. Another detail I liked is the rechargeable design, since it removes the need for disposable batteries and keeps the device ready whenever needed. After charging, it lasted through several grooming sessions before the battery indicator suggested another charge. The detachable heads rinse clean easily, which makes maintenance simple and keeps everything hygienic. It’s a compact grooming tool that manages to combine several functions in one device without feeling overly complicated.

Well that didn't last long
Color: Blue
Worked great at first, but only got it last November and it doesn't work now in April. I've cleaned it out totally and it still sounds awful. I don't know what's wrong. I mostly use this on my face every morning. It should have lasted longer.

oothbrush for My Cat and Small Dog – Gentle, Effective, and Easy to Use!
Color: Microbrush Kit, Color: Microbrush Kit
I’ve been using the Jasper Microbrush Cat Toothbrush for both my small dog and cat, and it’s hands down the best pet toothbrush I’ve tried! Here’s why I love it: Designed for Small Pets: The narrow head and tapered bristles are perfectly sized for smaller teeth. The “lip lifter” feature is genius—it really helps when my cat is being less cooperative about opening his mouth. It makes brushing much easier for both of my pets. Gentle on Teeth and Gums: The extra-soft bristles are perfect for my cat and dog, who are both a bit sensitive during brushing. I’ve noticed they’re much more comfortable with this toothbrush compared to others I’ve tried. Ergonomic and Easy to Use: The curved neck and soft-grip handle are so well-designed. It’s easy to reach the back teeth, and the non-slip handle gives me full control, even when my dog gets wiggly. Sustainable and Cost-Effective: I love the replaceable heads! It’s environmentally friendly and saves money over time. Plus, swapping the heads every few months keeps things hygienic without having to replace the entire toothbrush. Veterinary-Approved Quality: Knowing this was designed with a veterinary dentist gives me extra confidence in the product. It’s clear that a lot of thought went into making it safe and effective. Great for Both Pets: I use this toothbrush for my small dog and cat, and it works equally well for both. It’s versatile and eliminates the need to buy separate brushes. This toothbrush has made pet dental care so much easier and more effective. If you have a small dog, cat, or other small pet, this is a must-have for keeping their teeth clean and healthy. Highly recommend!

GREAT for small mouths!
Color: Microbrush Kit, Color: Microbrush Kit
The Pet toothbrush from Jasper is the perfect toothbrush for tiny mouths. I have two cats one that is under 10 lbs and one that is 17 lbs. This toothbrush works best for both of them! It is great to find a toothbrush that comes with multiple heads to use with my multiple cats! The handle is curved so it allows me to get into those hard to reach places which cats sometimes struggle to let you reach. The toothbrush was easy to use, and both of my cats had no problem with getting their teeth and gums cleaned. I also enjoyed that the brush heads are replaceable so one toothbrush handle can last a very long time! This starter pack is the perfect product to use when starting to brush their teeth. As the toothbrush is small, the bristles are gentle and the cat can chew on the toothbrush without them instantly destroying it. The toothbrush also holds onto the "toothpaste" product very well. There were not spills during the toothbrushing process. I definitely approved of this product and will continue to support this product in the future.
