A fuel inlet pipe (also called feed pipe or fuel supply pipe) is the front-section delivery line in the diesel engine fuel supply system, responsible for transporting fuel from the tank through the fuel filter to the injection pump or common-rail system inlet—the mandatory passage before fuel enters high-pressure injection. In automotive fuel systems, the supply pipe typically delivers fuel from the tank through the filter to the engine's fuel rail for temporary storage, then to the injectors for mixing with air upon energization; the return pipe sends excess fuel back to the tank—the two serving distinct roles, with the supply pipe generally having a larger diameter than the return pipe. On diesel engines, the fuel inlet pipe similarly handles the low-pressure supply task "from tank to injection pump / common rail," typically needing to withstand certain system pressures while operating long-term in harsh conditions of high temperature, vibration, oil contamination, and mud-water washing.
