Detailed Product Overview

Standard Ignition DIL49 is a diesel injector line intended for fuel injection system service on GM trucks and chassis equipped with an 8-cylinder diesel setup. This part cross-references Monroe Shocks & Struts (e.g., 800-96049, 10225928) for the same application. If you are replacing a worn or damaged diesel fuel injector line on a Chevrolet C2500, Chevrolet C3500, Chevrolet K2500, Chevrolet K3500, GMC C2500, GMC C3500, GMC K2500, or GMC K3500, DIL49 provides the correct external routing format for the listed vehicles.

What This Part Helps Address

• Fuel leakage from a cracked or fatigued injector line
• Hard starting caused by compromised diesel fuel delivery
• Rough idle related to inconsistent injector feed
• Visible corrosion or wear on an existing fuel injector line
• Fuel pressure loss at the injector circuit

Installation Notes and Tips

Verify engine configuration and line routing before installation. Because no gaskets, O-rings, hardware, or wiring harness are included, inspect the surrounding connections and replace any worn sealing components as needed during service. Confirm the line is installed in the correct external position and that all fittings are clean before tightening to specification.

Quality Assurance

Standard Ignition supplies application-specific replacement components for fuel system service. DIL49 is built for the listed diesel applications and should be matched to the vehicle’s year, make, model, and cylinder configuration before installation.
