Why This Part Matters

The 6.7L Power Stroke uses a high-pressure common-rail system. This rail-to-rail line equalizes pressure between the two fuel rails. It is frequently replaced during fuel system repairs—especially after CP4 pump failure (which can send metal debris through the system) or when performing a DCR conversion. Using the correct OEM line helps prevent leaks, maintains proper rail pressure, and protects injectors.

Note: Always replace high-pressure fuel lines as a complete, undamaged assembly. Do not reuse damaged or contaminated lines. Professional installation is recommended due to the high operating pressures in the 6.7L Power Stroke fuel system.
