How the design addresses contamination
The supplied design uses two lines with the specified connection location 25 inches from the CP4 pump. The return-filter assembly is intended to intercept contamination before it circulates to the tank and other fuel-system components. Treat the kit as a debris-management measure, not a replacement for diagnosing a failing pump or an already contaminated system.
Installation and ongoing maintenance
- Confirm the truck's engine and model year against the listed application.
- The quick-connect arrangement avoids cutting the original fuel lines as part of the stated installation.
- Keep the P550943 filter reference with your service records so the replacement element can be identified.
- Follow the installation and service instructions supplied with the kit.
Before you choose a kit
I already have a Gen2 kit. Do I need a complete replacement?
The existing product information identifies a Gen2.1 filter assembly or filter head as upgrade options. Ask JS Speed Diesel which component applies to your current kit before ordering another complete system.
Does the kit mean a damaged fuel system needs no further work?
No. Existing symptoms or contamination still need professional diagnosis. Confirm the required repair work before adding protective hardware.
What should I check when ordering a service filter?
Use the listed Donaldson part number P550943 and verify it against the filter assembly fitted to your truck.
