Description
Overview
Used RAIL feed tube designed for PSA Citroën and Peugeot vehicles, offered under part number 1570C1. Intended for the DW10TD (RHY) 2.0 HDi 90 (66 kW) engine family with Siemens injection components. The tube provides a sealed connection to the fuel rail and is supplied in a fully sealing condition as described by the original listing.
Function And Typical Failure Modes
The RAIL tube connects the fuel rail to the high‑pressure fuel system, ensuring correct fuel delivery to the injectors. Common reasons for replacement are external leaks at joints or fittings, mechanical damage from road debris or improper handling, and deterioration of sealing washers or O‑rings. Leaks may cause hard starting, rough running, fuel smell, or fuel pressure loss on the rail.
Replacement Guidance
Replacement is generally carried out when a leak or damage is found or when performing major fuel system repairs. Basic replacement steps for a qualified mechanic or competent DIYer:
- Relieve fuel system pressure and disconnect the battery before starting.
- Remove any engine covers or components blocking access to the rail and pipe.
- Carefully loosen the tube fittings at both ends, catch residual fuel, and replace old sealing washers or O‑rings with new ones.
- Refit the new tube ensuring correct alignment; tighten fittings to the manufacturer’s recommended torque and reassemble removed components.
- After installation, prime the fuel system, check for leaks, and verify correct engine operation before road use.
Service Life And Recommendations
There is no fixed replacement interval for the RAIL tube; it is a wear/condition item. Inspect during fuel system maintenance or when symptoms such as fuel odor, visible leakage, or pressure loss occur. Always use correct sealing parts and follow safe fuel‑handling procedures when replacing components.
Compatibility
Fits vehicles equipped with the DW10TD (RHY) 2.0 HDi 90 (66 kW) engine. Example models using this engine family include certain Peugeot 206, 307, 406, and Partner derivatives, and Citroën Xsara, Berlingo, and Dispatch variants (verify fitment by VIN and part number before ordering). Searching by part number 1570C1 will often return the correct applications for your vehicle.
