Supply Pipe From Pump To Rail For 1.4 HDI And 1.6 HDI EHDI Engines
Output Pipe Of The Injection Pump
Description
This feed pipe connects the high-pressure pump to the common rail on Citroën and Peugeot diesel engines with 1.4 HDi and 1.6 HDi e-HDi technology. Supplied under code 1570P8 (Stellantis), the component is designed to ensure reliable fuel delivery to the common rail and stable injection pressure for optimal engine performance. Ideal for professional workshops and experienced DIY mechanics, this part is an essential item when repairing fuel leaks, replacing damaged lines or servicing the high-pressure fuel system.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: 1.4 HDi, 1.6 HDi e-HDi (Common Rail Engines)
- Product Codes: 1570P8
- Additional Numbers: 1570P8
Installation Recommendations
Installation should be performed by a qualified technician or an experienced mechanic familiar with high-pressure diesel systems. Key steps and recommendations:
- Depressurize the fuel system before starting work (follow manufacturer service manual procedures).
- Work in a clean environment to avoid contamination of the high-pressure system.
- Replace all sealing elements (O-rings, crush washers) with new parts rated for high pressure.
- Fit the pipe without forcing connections; tighten fittings to the manufacturer’s torque specifications.
- After installation, bleed the fuel system and check for leaks at operating pressure. Run the engine and inspect all joints.
- Observe safety precautions for high-pressure fuel systems: avoid open flames, evacuate fuel spills and wear appropriate protection.
Why It Fails
Common causes of feed pipe failure include corrosion from moisture or contaminated fuel, mechanical damage from impact or improper routing, and deterioration of sealing rings leading to leaks. Excessive vibration, age-related metal fatigue and abrasive particles in the fuel can also lead to cracks or perforation. Failures are most often detected as visible external leaks, loss of fuel pressure, rough idling or warning lights related to fuel supply.
Practical Notes For Mechanics
- Inspect surrounding brackets and clamps during replacement; worn mounts can stress the pipe and accelerate failure.
- Always use matched sealing washers and ensure connectors are free of debris before assembly.
- If replacing the pipe due to a leak, clean the mating surfaces and consider replacing nearby flexible hoses and clamps as preventive maintenance.
Typical Applications
Designed for use on Citroën and Peugeot vehicles equipped with 1.4 HDi and 1.6 HDi e-HDi common rail diesel engines. Suitable for servicing fuel delivery from the high-pressure pump to the rail on a range of models using these engine families.
Ordering Tip
Search by code 1570P8 to quickly find this exact feed pipe. Provide engine type (1.4 HDi / 1.6 HDi e-HDi) when checking fitment in parts catalogs or workshop manuals.
