Diesel Fuel Injector Line for LB7 Applications

Standard Ignition DIL1 is a diesel fuel injector line for LB7-equipped Chevrolet Silverado 2500 HD, Silverado 3500, GMC Sierra 2500 HD, and Sierra 3500 models from 2001-2004. It is built for the high-pressure fuel delivery demands of these Duramax diesel applications and is shaped for direct fitment at the injector and fuel rail connection points.

  • High-grade steel construction with zinc coating to resist corrosion
  • Formed at the correct angle for accurate routing and easier installation
  • Ferrule tip ends designed to seal at the injector inlet and fuel rail outlet
  • Burst-tested for high-pressure diesel fuel system operation
  • Engine ID code LB7 and VIN code 1 application
  • Port quantity: 2

Detailed Product Overview

The Standard Ignition DIL1 diesel fuel injector line is engineered for the fuel system layout used on 2001-2004 Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and GMC Sierra 3500 trucks with the LB7 engine. Its steel tube construction and anti-corrosive finish help maintain durability in demanding underhood conditions, while the pre-formed bends support proper alignment during replacement. This part cross-references Dorman OE Solutions 904-129 for the same application.

Common Fuel System Issues Addressed

  • Fuel seepage at the injector or fuel rail connection
  • Corrosion on the original injector line
  • Cracked or weakened tubing from pressure cycling
  • Poor sealing caused by worn ferrule ends
  • Incorrect routing after prior fuel system service

Installation Notes

Verify LB7 engine identification before installation. This line is made for the specified injector and rail connection points on the listed Chevrolet Silverado and GMC Sierra diesel trucks. Gaskets are not included, and hardware is not included. Inspect mating surfaces, clean the connection points, and confirm proper tube alignment before tightening to specification.

Quality Assurance

Standard Ignition manufactures this injector line with corrosion-resistant steel and burst testing to support the pressure requirements of diesel fuel delivery systems. The zinc-coated finish adds protection against rust in service.
