• 【Direct Replacement 】 This fuel injector return hose assembly is specifically engineered for Cummins P7100 12-valve 5.9L diesel engines. Designed as a direct replacement for worn, cracked, or leaking factory return lines, it restores proper fuel flow and prevents messy fuel leaks. Replaces OEM part number 3926103.
• 【Prevents Fuel Leaks & Ensures Proper Return Flow】 The fuel leak off pipe routes excess fuel and pressure from the injectors back to the tank or injection pump. A damaged return line can cause hard starting, rough idle, and fuel starvation. This replacement pipe ensures fuel system operates at correct pressure, maintaining engine performance and reliability.
• 【Heavy-Duty Metal Construction】 Unlike OEM plastic lines that become brittle and crack over time with heat and vibration, this return hose is crafted from robust metal material for superior durability. The sturdy construction withstands high under-hood temperatures, diesel fuel exposure, and the constant vibration diesel, ensuring long-lasting service life.
• 【Easy DIY Installation】 Designed for straightforward installation with no special tools required. Simply remove the damaged factory return line and install this direct-fit replacement using your existing hardware. Perfect for diesel enthusiasts and mechanics looking to restore their 12-valve fuel system without complicated modifications.
• 【Essential Maintenance 】 The P7100 injection pump is legendary for reliability, but original fuel return lines are known to fail with age. Replacing brittle, leaking return pipes with this metal version prevents air from entering the fuel system, eliminates messy engine bay leaks, and keeps with 5.9L 12V running smoothly. Please verify your engine type (for Cummins P7100 12V only) before ordering.
