Description
RAIL outlet pipe for the injection pump on 1.6 HDi diesel engines. This high-pressure fuel line (part number 1570H5) transfers pressurised fuel from the injection pump to the common rail, ensuring stable fuel supply and engine performance. It is suited for professional workshops and knowledgeable DIY mechanics working on PSA vehicles.
Purpose and common failure modes: The outlet pipe carries high-pressure fuel; leaks or cracks lead to pressure loss, hard starting, misfires, fuel smell or visible leaks. Failures are commonly caused by corrosion, vibration fatigue, impact damage or loose fittings. Regular inspection of unions and sealing washers helps prevent sudden failures.
Replacement and installation notes: Before replacement, depressurise the fuel system and disconnect the battery. Use two wrenches to avoid twisting fittings, replace sealing (crush) washers at each connection, and tighten to the manufacturer’s torque specification (consult the workshop manual). After installation, bleed the fuel system and check for leaks at operating pressure. Avoid contaminating the openings and always use clean tools and new washers.
Service interval: The pipe is not a routine wear item; replace when damaged or leaking. Lifespan depends on driving conditions and maintenance. Inspect during any fuel-system service or when symptoms appear.
