About this part
The 3685808 Injector Fuel Supply Tube is a specific part designed for Cummins fuel injectors. This supply tube is essential for delivering fuel to the injector, ensuring optimal performance and efficiency in engine operation. With the trusted brand of Cummins behind it, you can rely on this fuel supply tube to provide reliable fuel delivery for your vehicle.
The Cummins 3685808 is an injector fuel supply tube, the short connector that carries fuel from the high-pressure line into the injector. Supply tubes are usually replaced along with the injector, or when the sealing tip wears and causes fuel leaks, hard starting or misfires.
Before you order: confirm 3685808 against your Cummins engine serial number in the parts book. Use a new tube whenever you swap an injector, and tighten it to the engine's specification so it seats squarely against the injector.
