Keep Your Powerstroke Running Clean Without Breaking A Sweat

If you're fed up with the headaches caused by water and debris in your diesel fuel, the FASS Drop-In Series Diesel Fuel System is the kind of upgrade you’ll wish you made sooner. This isn’t some overcomplicated, custom rig that takes a weekend to install. It's a true drop-in solution designed specifically for your 2017–2024 Ford 6.7L Powerstroke. You don’t need to cut, wire, or mess around with your factory in-tank pump. Just bolt it in where your factory water separator sits and you're good to go. What really makes this system stand out is its ability to remove over 99% of water and separate entrained air before it ever reaches your injectors. That kind of protection doesn’t just help your truck run smoother, it can prevent thousands of dollars in fuel system damage. Whether you're hauling for work or daily driving, this system improves throttle response and keeps your diesel running clean, quiet, and efficient. Plus, with options for electric heaters, cold starts just got a whole lot easier.

Performance Backed By Precision Engineering And Real World Testing

This isn’t just a quick fix, it’s a performance upgrade built with precision from the inside out. The FASS Drop-In Series includes advanced features like internal air separation passages and Performance Radius Cuts that smooth out fuel flow by eliminating sharp 90-degree angles that can disrupt velocity. These cuts reduce turbulence and help maintain fuel integrity all the way to your injectors. Combined with a 2-micron filtration rating and industry-best water separation, this system sets a new bar for protecting modern diesel injection systems. Even better, it’s the only drop-in 6.7L Powerstroke filtration system that maintains full functionality of the OEM water-in-fuel sensor while improving lubricity by up to 10%. That means better wear protection for your injectors and a noticeable bump in responsiveness. This setup delivers the same quality of filtration as FASS’s top-tier Titanium Signature and Industrial Series, all packed into a quick-install kit. It’s engineered to fit perfectly and work flawlessly, no shortcuts, no compromises.
