CP4-6.7F-BP-G2.1-FHU S&S Diesel CP4 Bypass Return Filter Head Upgrade - Ford 6.7L Powerstroke 2011-2022

Overview

The S&S Diesel Bypass Return Filter Assembly can be used to upgrade the first-generation bypass kit on your truck. Ideal for those looking to significantly improve the debris management of their first-generation kit. The main task of both kits is to supply the CP4 case and the metering unit/plungers independently with clean, filtered fuel and to reroute case fuel back to the tank. The Gen2.1 features a billet return filter head that accepts a Donaldson P550943 spin-on fuel filter which prevents debris from reaching the tank, fuel lines and supply pump. This return filter assembly lets you easily upgrade your existing S&S Gen1 kit and take advantage of the Gen2.1 improvements.

The new Gen2.1 return filter head uses the same quick connect fittings and mounting hardware as the previous Gen2 filter, which allows for an easy retrofit. S&S customers who already own a Gen2 CP4 Disaster Prevention Kit can purchase the Gen2.1 Filter Head Upgrade (CP4-6.7F-BP-G2.1-FHU) to update their kit to the Gen2.1 spec. When considering future filter changes, the Donaldson P550943 replacement filters will be much less than the previous Gen2 filters, and they can be purchased from most auto parts stores.
