Overview

Meet the KPALAG diesel fuel injector return line assembly set, designed to fit Duramax-powered GM trucks from 2004.5 through 2010. This replacement duo reestablishes reliable fuel return routing and seal integrity, helping your engine bay stay organized while you perform maintenance or upgrades.

The components are built to endure the challenges of daily driving and high-heat engine environments. With precision-fit connections and robust materials, these lines are crafted to work with your truck’s existing fuel system without complicating installation.

Premium materials and construction

  • Aluminum connectors with anti-corrosion coating for long-lasting, dependable fit.
  • Thickened nitrile rubber hose optimized for fuel exposure and oil resistance.
  • Nylon braid reinforcement adds elasticity and helps shield the hose from wear.
  • Outer protective layer delivers thermal insulation and enhanced abrasion resistance for harsher under-hood conditions.

Compatibility and reference

The kit aligns with 2004–2010 GM Duramax engines (6.6L LLY/LBZ/LMM) and compatible GM platforms such as Silverado/Sierra 2500HD/3500HD. Cross-reference part numbers include 98062291, 97328733, 97328732, and 97359750 for matching options.

What’s included

  • 1× Passenger right side fuel injector fuel return line assembly
  • 1× Driver left side fuel injector fuel return line assembly
  • 8× Retainer clips (fuel return line to injector)
  • 2× O-rings
  • 2× Stainless steel clamps

Real-world use suggests replacing aging return lines can help mitigate leaks from cracks or heat stress and restore clean routing in the Duramax engine bay. Individual results vary by vehicle condition and maintenance history, but the configuration is designed to support straightforward installation and durable performance.
