Fleece Performance 11-16 GM 2500/3500 Duramax LML Replacement CP3 Return Hose

Fleece Performance is known for making well-built parts for diesel trucks. This replacement CP3 return hose is designed for the 2011-2016 Chevrolet Silverado 2500 HD and 3500 HD, as well as the GMC Sierra 2500 HD and 3500 HD equipped with the Duramax LML engine. It's a direct replacement for the original hose, ensuring your fuel system continues to function as it should.

This hose connects the fuel pressure regulator back to the CP3 injection pump, allowing excess fuel to return. Over time, these hoses can crack or become brittle, leading to fuel leaks or performance issues. Replacing it with a new, well-made hose like this one from Fleece Performance helps maintain proper fuel pressure and prevents potential problems down the road.
