Glacier Diesel Power 2007.5-2018 Dodge Ram 6.7L Cummins -6AN High Flow CP3 Inlet Adapter

When upgrading the fuel system on your 2007.5-2018 6.7L Cummins, it's easy to focus on lift pumps, larger fuel lines, and injectors while overlooking one of the biggest restrictions in the system—the factory CP3 injection pump inlet fitting. The Glacier Diesel Power -6AN High Flow CP3 Inlet Adapter replaces the restrictive factory fitting with a precision-machined high-flow adapter that increases the internal passage from approximately 0.185" to 0.300", helping reduce a bottleneck at the CP3 inlet.

Designed specifically for the 2007.5-2018 6.7L Cummins CP3 injection pump, this adapter features a 12mm x 1.5 O-ring (ORB) metric connection, includes a high-quality Viton O-ring, and converts the pump inlet to a -6AN male fitting for easy connection to aftermarket fuel systems, custom fuel plumbing, and performance applications.
