Upgrade Your Fuel System Without Starting from Scratch

If you’re already running the Gen2 S&S Diesel CP4 Disaster Prevention Kit on your 2011-2025 Ford 6.7L Power Stroke, the Gen2.1 Filter Head Upgrade is the next smart move. This upgrade brings your existing setup up to the latest Gen2.1 spec without needing to buy a whole new kit. What makes the Gen2.1 head different is its ability to work with the more efficient Donaldson spin-on return filter, which improves how debris is captured and prevents it from making its way back into the fuel tank. That added layer of protection is key, especially in the event of a CP4 pump failure. The best part? This upgrade reuses your current quick connect fittings and mounting hardware, so installation is quick and doesn’t require cutting, special tools, or fabrication. If you've already invested in a Gen2 system, this upgrade helps you get more from it, both in performance and peace of mind.

Better Filtration with Easier Maintenance

The new Gen2.1 filter head is precision-machined from billet aluminum for strength, durability, and clean fitment. It’s designed to accept the widely available Donaldson P550943 spin-on filter, which captures debris at a 9-micron level with 99% efficiency. That means it not only provides better protection but also makes filter changes easier and more affordable compared to the earlier filter design. Whether you use your Super Duty for towing, jobsite work, or daily driving, this upgrade is a simple way to boost reliability without redoing your entire fuel protection system. For anyone who already took the step to install the Gen2 kit, this is an easy, affordable improvement that adds real value and updated engineering to your setup, all while keeping downtime to a minimum.
