BD Diesel 1050140 Fuel Injector Line Set Duramax LB7 6.6L 2001-2004

The BD Diesel 1050140 is a complete stock replacement fuel injector feed line set designed specifically for 2001-2004 Chevrolet and GMC Duramax 6.6L LB7 engines in 2500 and 3500 series trucks. These high-quality fuel lines are engineered to restore proper fuel delivery from the high-pressure fuel rails to each injector.

Key Features:

• Zinc-plated construction for superior corrosion resistance against harsh underhood conditions
• Preformed to exact OEM specifications for precise factory fit with no adjustments required
• Direct replacement for GM OE part numbers 97188720, 97188721, 97188722, and 97188723
• Complete 8-piece set includes all injector feed lines (2 of each part number)
• OEM quality materials and construction ensure reliable performance and longevity

Fuel injector lines on the LB7 Duramax are exposed to constant heat, vibration, and moisture, which causes the factory steel lines to rust and corrode over time. GM strongly recommends replacing these lines anytime they are removed during injector service. The BD Diesel zinc-plated lines offer significantly better corrosion protection than the original equipment, helping prevent future fuel system issues.

Installation & Warranty:

• Estimated installation time: 7 hours
• Includes 24-month parts warranty
• 50-state legal emissions compliant (California EO not required)

This is an essential upgrade when performing injector service on LB7 Duramax engines, providing peace of mind with improved corrosion resistance and reliable fuel system performance.
