1998.5-2022 Cummins Individual Connector Tubes

Fits

Complete your injector installation with confidence using Dynomite Diesel OEM Replacement Injector Connector Tubes. These high-quality tubes are essential for maintaining a leak-free seal between your high-pressure fuel lines and injectors. Unlike cheap aftermarket knock-offs, these are genuine OEM-spec tubes designed to handle extreme rail pressures. Whether you are performing a standard maintenance refresh or a high-performance injector upgrade, these tubes provide the reliability and precision fitment your Cummins engine demands.

• Genuine OEM quality for a reliable, leak-free fuel system seal
• Includes brand-new O-rings for every tube
• Application-specific designs for 24V, 5.9L CR, and 6.7L platforms
• Direct-fit replacement for worn or contaminated factory tubes
• Sold individually to accommodate single injector repairs or full sets

• Select Your Application: Please choose the correct year range and engine model for your truck. These tubes are specific to the engine's fuel system architecture.
• The 5.9L Advantage (2003-2007): For Common Rail 5.9L owners, Dynomite Diesel provides actual 5.9L tubes rather than the 6.7L supersessions. These are less prone to leaking in 5.9L heads and are the preferred choice for builds under 1,000 RWHP.
• Quantity: These are sold individually. If you are replacing a full set of injectors, please adjust your quantity to 6.
• Installation Tip: It is highly recommended to replace your connector tubes whenever new injectors are installed to prevent high-pressure fuel leaks and cross-threading issues.
• Cleaning: Always ensure the connector tube port in the cylinder head is clean and free of debris before inserting the new tube to ensure a proper seat.
• Emissions: Select models are not for sale or use in the state of California.
