CP4-6.7F-G2.1-RFA S&S Diesel CP4 Bypass Return Filter Assembly - 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.
