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 hose filter for filling hot tubs
Style: Standard Filter
I bought this for filling up my hot tub. It does the trick. Straight tap water was difficult to balance the ph and keep it stable. When I fill the hot tub using the filter, the water is more balanced and easier to maintain. I used it for two 390gal refills before I noticed it was getting slower, so ordered another one. I haven’t used it for drinking water so can’t comment on the taste. It does seem to help with hardness though.

This new and advanced inline water filter offers a perfect combination of convenience, effectiveness, and durability, making it an essential addition for any RV owner. First and foremost, the performance of the Camco TastePURE Water Filter is impressive. It effectively removes impurities, odors, and bad tastes from the water, providing clean and fresh drinking water directly from the tap. The advanced filtration system reduces chlorine, sediment, and other contaminants, ensuring the water is safe and pleasant to drink. The inclusion of a flexible hose is a standout feature. The hose makes it easy to connect the filter to various water sources without straining or kinking.

The hose also helps to relieve pressure on the connections, reducing the risk of leaks. Installation is straightforward and user-friendly. The filter comes with clear instructions, and the connections are standard, making it easy to attach to most water sources and RV plumbing systems.

Made from high-quality materials, the filter is built to withstand the rigors of outdoor use and frequent travel. The sturdy construction ensures it can handle varying water pressures without cracking or leaking, providing reliable performance throughout its lifespan. One of the major advantages of this water filter is its versatility. It is not only suitable for RVs but can also be used for boats, trailers, and even at home with garden hoses. This multipurpose functionality makes it a valuable investment for anyone looking to improve water quality in various settings. Maintenance of the filter is minimal and straightforward. The replaceable filter cartridges are easy to change, and the clear housing allows you to monitor the filter's condition and know when it's time for a replacement. This convenience ensures that maintaining clean and safe water is a simple and manageable task. In terms of value for money, the Camco TastePURE Water Filter is excellent. The combination of high-quality filtration, ease of use, and durability makes it a cost-effective solution for ensuring clean water in your RV. The peace of mind that comes with knowing you have access to safe drinking water is well worth the investment.

It works
Size: S
On my bottling buckets, two from different manufacturers, it clamps well and keeps the racking cane out of the sediment at the bottom. It beats running the beer through a tight mesh bag. Lots easier. Should have gotten a racking cane, and a clamp, earlier.

Works perfectly!
Size: S
This clamp works perfectly! Holds the siphon tube securely. When you buy one of these clamps, measure the inside siphon tube. Not the outside tube the inner tube slides in. This was a bit confusing, but I got the right one and I'm happy with it!
