Description
The FASS Drop-In Series Diesel Fuel System was carefully designed to provide the best filtration solution for the 6.7L Powerstroke. The Drop-In Series System effectively safeguards the 6.7L Powerstroke injection system from premature failure by eliminating over 99% of water, entrained air, and debris down to 2 Microns from your diesel fuel. This helps prevent excessive wear and potentially saves you thousands of dollars in repair costs. Additionally, by eliminating the contaminants mentioned above, the Drop-In Series System for the 6.7L Powerstroke optimizes MPG (results will vary), restores horsepower, and sharpens throttle response.And if reliability, optimized MPG, restored horsepower, and a sharper throttle response aren’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.This industry-leading water removal capabilities (3rd-party proven to exceed 99%) are reinforced by the unique design of the Extreme Water Separator (XWS). If the XWS reaches capacity, it acts as a dam, shutting down the truck and preventing major destruction of fuel system components. FASS DROP-IN TECHNOLOGY FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation, making the 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 the Titanium Signature Series and Industrial Series lines. PERFORMANCE RADIUS CUTS Performance Radius Cuts are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth-flowing cuts within the filtration system. 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 the fuel fuel. DIFS SPACER KIT This kit is necessary when installing the Drop-In Series System on a 2017-2024 6.7L Powerstroke with an S&B or Titan fuel tank. Due to the larger capacity of these tanks, this kit places the fuel lines in the correct position for a seamless integration with the S&B or Titan tank.

About FASS Fuel Systems

FASS Fuel Systems is an American manufacturing company specializing in the engineering, design, and production of fuel systems and accessories for diesel vehicles.

FASS builds vehicle specific fuel / lift pumps of varying levels of displacement to meet the needs of the exact build level of your Dodge Ram with a 5.9L or 6.7L Cummins engine, Ford with a Powerstroke engine, Chevrolet or GMC with a Duramax engine, or even your Big Rig Class 8.

And because sometimes you might find yourself in the middle of nowhere with a bad batch of fuel and no extra FASS filters, FASS systems are designed with cross reference filters in mind, and they even publish that cross reference sheet on their website. When installing a FASS system, or maybe after the fact, maybe you want to eliminate the ugly, unused stock fuel filter¦.no problem, FASS has a complete line up of fuel filter deletes and other accessories to clean up your engine bay. Maybe you live in a colder climate and realizing that once you bypassed your stock fuel filter it also removed your stock fuel heater¦.FASS has you covered yet again. Yes, you can have all of the factory creature comforts but still a high flowing, properly filtered fuel system.

EXPERIENCE A FASS FUEL SYSTEM FOR YOURSELF

While FASS is most known for their Titanium Signature Series Fuel System that includes an integrated fuel filter and water separator, FASS also builds other popular systems. Do you like the idea of a higher volume frame mounted lift pump, but prefer to keep the stock filtration and fuel heater? The Signature Series Adjustable Fuel Pumps are your answer. Or maybe youve got a Cummins with the original block mounted pump thats finally let go and youre not ready to invest in a complete system. Okay, the DRP (Direct Replacement Pump) is a great option. Maybe you have a Duramax and just looking for a little extra oomph of fuel to your injection pump. Similar to the DRP for Rams, FASS has their Dura-Max Diesel Flow Enhancer.

Overall, you can never go wrong upgrading your truck with a FASS Fuel System. As always, if you have any questions about which system is right for you, dont hesitate to reach out and we will be happy to steer you in the right direction.
