Industrial Injection 237403 Cummins Common Rail 5.9L Dual Feed Fuel Line Kit

Industrial Injection's Dual Feed Fuel Line is a high-performance fuel system upgrade designed to increase fuel volume and maintain consistent rail pressure in the 5.9L Cummins common rail fuel system. This steel-encased rigid fuel line routes from the CP3 injection pump directly to the common rail, providing a second feed path that helps sustain fuel pressure under high-demand conditions.

Key Features:

• Steel-encased rigid construction for durability and reliable high-pressure fuel delivery
• Increases fuel volume to the common rail, improving pressure stability under load
• Routes from the CP3 injection pump to the top of the fuel rail — adds a second supply path for enhanced flow
• Compatible with modified CP3 injection pumps — an ideal complement to upgraded high-pressure fuel systems
• Helps prevent rail pressure relief valve failure by reducing pressure spikes and fuel starvation events
• Kit includes all hardware necessary for installation

The Industrial Injection 237403 Dual Feed Fuel Line is a proven solution for diesel enthusiasts running performance-modified 5.9L Cummins engines. Whether you've already experienced a blown rail pressure relief valve or are looking to proactively protect your common rail system, this dual feed line delivers the additional fuel flow your upgraded engine demands.
