XDP XD607 OER SERIES FUEL RETURN LINE ASSEMBLY 2011-2016 GM DURAMAX 6.6L LML/LGH

Restore the heart of your vehicle with the XDP OER Series Fuel Return Line Assembly XD607 designed for the 2011-2016 GM 6.6L Duramax LML/LGH engines. If you've faced the unfortunate issue of a CP4 pump failure, chances are contaminants and debris have infiltrated your fuel system, wreaking havoc along the way.

Metal shavings and impurities can clog the regulator and hinder proper fuel pressure return through the line, leading to potential complications. To ensure a thorough cleanse and to safeguard your new fuel system components from future contamination, it's advisable to replace the entire fuel system, including the fuel return line.

Over time, rubber hoses can deteriorate, becoming rigid and prone to cracking. Even if the exterior appears intact, interior damage can compromise their functionality and integrity. The OER Series regulated injector return line assembly offers a solution that services both banks while incorporating a regulated return valve for optimal performance.

This direct-fit assembly serves various Chevy and GMC models from 2011 to 2016, including Silverado, Sierra, Express, and Savana variants running on the Duramax LML and LGH engines. Say goodbye to fuel system woes and welcome the reliability and quality of the XDP XD607 OER Series Fuel Return Line Assembly to keep your vehicle running smoothly.
