This 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% 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, Fass's Drop-In Series System for the L5P Duramax optimizes MPG (results will vary), restores horsepower, and sharpens throttle response.
Fass's industry-leading water removal capabilities (3rd-party proven to exceed 99%) are reinforced by the unique design of Fass's Extreme Water Separator (XWS). If Fass's XWS reaches capacity, it acts as a dam, shutting down your truck and preventing major destruction of fuel system components.

Additional Info
Additional Info
- FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation—making Fass's 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—Fass's Drop-In Series Fuel Systems offer the same world-class filtration as Fass's 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° 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° fittings that can limit fuel flow, cause restrictions and reintroduce air back into your fuel.
FAQ
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) by 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. Fass has the only Drop-In style system that allows the water in 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!
