Quick Ship SKU #: FASS-DIFSL5P1001-Main FASS Fuel Systems Drop-In Series Fuel Filtration System 17-24 GM 6.6L Duramax Crew Cab

Protect your L5P's injection system from premature failure with the FASS Drop-In Series Fuel System. This system can be installed in less than an hour and is the most cost effective solution to protect your L5P's injection system. Without proper fuel filtration, your L5P's injection system is 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 and gains reliability, optimized fuel economy, and sharper throttle response. This is a true plug and play system that requires no cutting, welding, tuning, or additional modifications. FASS's industry-leading water removal capabilities (3rd-party proven to exceed 99%) are reinforced by the unique design of their Extreme Water Separator (XWS). If the XWS reaches capacity, it acts as a dam, shutting down your truck and preventing major destruction of fuel system components.

FASS DROP-IN TECHNOLOGY:

This 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-the Drop-In Series Fuel Systems offer the same world-class filtration as FASS's Titanium Signature Series and Industrial Series lines.

PERFORMANCE RADIUS CUTS:

These 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.
