Cummins 393200700 Fuel Injector Supply Line

The Cummins 393200700 fuel injector supply line is engineered for precise fuel delivery within high-pressure injection systems. Constructed from high-strength steel tubing with corrosion-resistant coating, it ensures reliable sealing and durability under extreme operating pressures and thermal cycles. This component is critical for maintaining injection timing accuracy and combustion efficiency in Cummins B-series and ISB/QSB engine platforms. Designed as direct OEM replacement for Cummins part number 393200700, it restores fuel system integrity and prevents leakage-related performance degradation. Compatible with Cummins 5.9L engine variants including 6BT, ISB, and QSB configurations commonly found in heavy-duty trucks and construction machinery. Each line is manufactured to strict dimensional tolerances for proper fitment at the injector inlet and high-pressure connector.
