FASS Drop-In Series Diesel Fuel System for 2020-2024, GM (DIFSL5P2001)

 

The FASS DIFSL5P2001 Drop-In Series Diesel Fuel System is the ultimate filtration solution for the L5P Duramax, designed to protect against fuel contamination and backed by a limited lifetime warranty. By removing over 99% of water, air, and debris down to 2 microns, it shields your injection system from costly damage.

This system not only prevents premature failure but also improves MPG, restores horsepower, and enhances throttle response. Plus, it installs in under an hour with no cutting, wiring, or tuning changes needed. Whether stock or modified, your L5P Duramax benefits from this plug-and-play system.

Our Extreme Water Separator (XWS) provides superior water removal, ensuring that if it reaches capacity, it shuts down the truck to prevent fuel system damage.

 

Please Note: Installation of this kit on a cab and chassis may require modifications. Drop-In Fuel Systems are a plug-and-play filtration upgrade and are not compatible with our Fuel Sump Kit. No additional items are needed for installation. This plug-and-play filtration system utilizes the L5P Duramax OEM in-tank fuel pump for fuel flow.

FASS Drop-In Series Duramax FAQ
  • Will the Drop-In Series System for the L5P Create Excessive Back Pressure on the Lift Pump?
    In short, no! Through extensive engineering and testing, the FASS R&D team was able to decrease pressure drop (differential pressure) approximately 1 PSI from the OEM filtration system. This was accomplished by maximizing the internal porting size to allow a system that flows more freely in addition to adding superior filtration.

 

  • Why Does the Drop-In Series for the L5P Utilize an OEM Water Separator?
    The reason we utilize the OEM water separator is due to the design of the OEM water in fuel sensor/fuel heater. We are the only Drop-In style system that allows the water in the fuel sensor to properly function as they must be on the DIRTY SIDE of the water separator element to detect the water before it makes it to the clean side. If the sensor is placed on the clean side of the element, by the time the sensor detects the water it is too late! With the Drop-In Series FASS, you will get properly functioning water in fuel light and fuel heater!
