DDP J01572 Fuel Injector Connector Tube for 2003-2007 Dodge Ram 5.9L Cummins

The DDP J01572 is a high-quality fuel injector connector tube specifically designed for 2003-2007 Dodge Ram trucks equipped with the 5.9L Cummins diesel engine. This is an actual 5.9L tube, not a 6.7L tube like others. This critical fuel system component transfers high-pressure fuel from the common rail injection line to the fuel injector inside the cylinder head.

Key Features:

• Genuine 5.9L-specific design for optimal sealing and performance
• Forms a metal-to-metal seal capable of containing 25,000+ PSI
• Direct replacement for OEM part numbers including F00RJ01572, 4929864, 4928589, and 68005335AA
• Includes O-ring for proper installation
• Manufactured to exacting specifications for reliable fuel delivery

Why Choose the 5.9L-Specific Tube:

Cummins and Chrysler have superseded all their part numbers for a 5.9L connector tube over to a 6.7L tube. The issue with this is that the 6.7L connector tube has a higher likelihood of leaking compared to the 5.9L tube. For this reason, we still sell 5.9L tubes to ensure you have a trouble free injector install. The 5.9L-specific design provides superior sealing characteristics and reliability for 2003-2007 applications.

Installation Notes:

Connector tubes should always be replaced when servicing or replacing fuel injectors. Reusing old tubes can result in fuel leaks, hard starting, rough idle, and potential damage to new injectors. The tubes form a critical seal at the injector and experience wear that prevents proper seating with replacement injectors. Torque specification is 37 ft-lbs on the connector tube nut. Sold individually—six tubes required per engine.
