Description
Used RAIL supply pipe for PSA 2.0 HDi 90 (66 kW) engines, engine codes RHY / DW10TD, supplied by Siemens. The part is in fully sealing condition and is intended for Citroën and Peugeot vehicles using the DW10TD fuel system. This component is frequently searched by its OE number 1570C1.
Function
The RAIL supply pipe carries high-pressure fuel between the common rail and related components (injectors or high-pressure pump connection depending on layout). It maintains the required fuel delivery pressure to ensure correct injector operation and stable engine performance.
Installation and Fitment
Installation requires depressurizing the fuel system first and following standard diesel-fuel safety procedures. Typical steps: relieve fuel pressure, remove engine covers as needed, disconnect the high-pressure line at the rail and pump, replace sealing washers/O-rings, fit the new pipe and tighten connections to manufacturer torque specifications. Work should be performed by qualified technicians or experienced DIYers familiar with high-pressure diesel systems.
Common Faults and Lifespan
Failures commonly result from worn or damaged sealing rings, corrosion, mechanical impact, or vibration-induced stress. Lifespan depends on vehicle usage and maintenance; inspect the pipe when diagnosing fuel leaks, loss of fuel pressure, or after injector/rail servicing.
