Description
Product Overview
High-pressure RAIL pipe manufactured for PSA diesel engines, offered as a used unit and described as fully sealing. This fuel rail pipe corresponds to part number 1570C2 and is associated with Siemens-supplied common-rail components for the 2.0 HDi (DW10TD, RHY) 90 (66 kW) engine. It is an ideal replacement when the original pipe shows leaks, corrosion or mechanical damage and is frequently searched by part number 1570C2.
Function and Benefits
The rail pipe routes high-pressure diesel from the common rail to the injectors, maintaining the correct pressure and sealing at the injector interface. A properly sealing pipe prevents fuel leaks, preserves system pressure, and supports reliable engine performance. Buying this exact part number increases the chance of correct fitment and reduces diagnostic time for technicians.
Installation & Maintenance
Replacement should be performed by a qualified technician or an experienced DIY mechanic familiar with common-rail diesel systems. Basic steps:
- Depressurise the fuel system according to the vehicle service procedure before starting.
- Clean the surrounding area to avoid contamination of the rail and injectors.
- Remove retaining clips, banjo bolts or fittings securing the pipe to the rail and injectors.
- Replace sealing washers (copper or crush washers) and any damaged clamps or fasteners.
- Install the new pipe, tighten fittings to the manufacturer’s torque specifications and check for leaks under pressure.
- After installation, inspect for leaks and confirm correct engine running before road testing.
Common Failure Modes
Rail pipes may fail due to corrosion, vibration fatigue, physical impact or deterioration of sealing washers. Leaks can lead to reduced rail pressure, injector issues, poor starting, rough idling or visible fuel seepage. Regular inspections during servicing help catch damage early.
Compatibility Notes
This pipe is intended for PSA 2.0 HDi common-rail engines of the DW10TD family (engine code RHY). It is commonly used across a range of Citroën and Peugeot vehicles fitted with the 2.0 HDi engine. For example, many technicians find the DW10TD engine in models such as Peugeot 307 and 407 and Citroën C4 and C5, but always verify fitment by part number 1570C2 before ordering.
