This EZROAD low pressure fuel line kit is designed as a direct replacement for the factory fuel lines on specific Duramax diesel engines.

Constructed from durable rubber with reinforced layers, the hoses resist oil, heat, and pressure fluctuations common in high-mileage pickup applications. The kit includes all necessary pre-formed lines, connectors, and clamps to install on LBZ and LMM variants equipped with 6.6L engines and VIN codes D or 6. Each line is precision-molded to match OEM routing, ensuring a secure seal at the fuel filter housing, injection pump, and cylinder head connections. The rubber material maintains flexibility in cold weather while retaining strength under continuous fuel flow, reducing the risk of future cracks or leaks. By restoring proper fuel pressure delivery, this kit helps maintain consistent engine performance and fuel efficiency. The affordable price point makes it a practical option for both DIY mechanics and professional technicians who need a reliable, cost-effective part without compromising durability. All components are quality-checked for fitment and finish before packaging. This kit does not require special tools for installation, though basic mechanical knowledge is recommended. The package contains multiple hoses and hardware pieces, each clearly labeled for easy identification. Users should verify their vehicle application against the listed OE numbers to confirm compatibility. The product is suitable for standard diesel fuel and biodiesel blends up to B20. Regular inspection of fuel lines is always advised, and this kit provides a complete solution for those experiencing age-related deterioration or aftermarket modifications. The materials used are selected for long service life in engine bay conditions, including exposure to vibration and engine heat. While not a performance upgrade, this replacement parts serves to return the fuel system to its designed operating parameters.
