Description
Supply pipe for the first and second cylinder. For RAIL 1.4 HDI 16V 8HY.
This high-pressure feed pipe (part number 1570F6) is designed to route fuel from the common rail to the injectors for cylinders 1 and 2 on 1.4 HDi 16V engines. It is a direct-fit component used on Stellantis petrol/diesel common-rail systems in a number of small Citroën and Peugeot models. Ideal for professional garages and experienced DIY mechanics who need a reliable replacement line to restore proper fuel delivery and engine performance.
Key Features and Benefits
- Direct Fit Replacement: Matches original routing and connections for the RAIL 1.4 HDI 16V (Engine Code 8HY).
- Restores Fuel Delivery: Ensures correct high-pressure fuel supply to Cylinders 1 and 2 for smooth idling and power delivery.
- Durable Construction: Metal fuel line designed to withstand common-rail pressures and engine bay conditions.
- Improves Reliability: Replacing a leaking or damaged pipe eliminates fuel smell, loss of power, and potential safety hazards.
How To Replace
- Relieve Fuel Pressure Safely: Follow manufacturer procedure to depressurize the common rail before opening lines.
- Access The Rail: Remove any engine covers or heat shields that block access to the fuel rail and lines.
- Disconnect Fittings: Loosen and remove the retaining fittings (banjo or flare connections as applicable). Keep track of sealing washers.
- Install New Pipe: Fit the replacement pipe in the same orientation, use new crush washers or seals where required, and tighten fittings to the manufacturer torque specification.
- Check For Leaks: Re-pressurize the system and inspect all joints with the engine off, then run the engine and re-check for leaks and correct operation.

Installation Recommendations
Always depressurize the fuel system before loosening any connections. Replace sealing washers or O-rings with new parts to ensure leak-free joints. Use the correct torque values from the vehicle manufacturer when tightening fittings. Work in a well-ventilated area and avoid open flames or sparks while handling fuel components. If unsure about the procedure, have the replacement carried out by a qualified technician.
Most Common Reason For Failure
These feed pipes typically fail due to external corrosion, vibration fatigue or damage from improper handling during previous repairs. Leaks most often occur at connection points where crush washers or seals have deteriorated. Contamination in the fuel system or mechanical impact can also cause cracking or deformation of the pipe, resulting in loss of fuel pressure, rough running, or visible fuel leakage.
