Description
Fuel Supply Pipe 1.4 HDi 66 kW Delphi System
This fuel supply pipe is designed for vehicles equipped with the Delphi fuel system and the 1.4 HDi 66 kW engine. It provides a direct-fit replacement that restores secure fuel delivery and sealing between fuel system components, helping to prevent leaks and maintain proper engine performance. Ideal for professional workshops and skilled DIY mechanics who need a reliable, correctly sized fuel line for Citroën and Peugeot applications.
The component carries the common part number used in many spare-part lookups, making it quick to find when searching by code. It is intended to replace worn or damaged feed lines that can cause poor fuel flow, fuel smell in the engine bay, or starting and idle issues. Installation is straightforward for anyone familiar with diesel fuel systems, but must be carried out with care due to fuel pressure and flammability.

Installation Recommendations
Work Safely: Perform the replacement in a well-ventilated area, away from open flames or sparks. Relieve Fuel Pressure And Isolate Electrical Supply Before Starting—remove the fuel pump fuse or relay and disconnect the negative battery terminal.
Replacement Steps (Overview):
- Depressurize the fuel system according to workshop procedure (crank engine after isolating pump or follow manufacturer instructions).
- Locate the faulty feed pipe and note routing and clamp positions for correct reassembly.
- Carefully disconnect fittings—catch spilled fuel and replace any sealing O-rings or gaskets with new parts.
- Install the new pipe following the original routing, secure clamps and fittings, and torque connections to specification where applicable.
- Reconnect the fuel pump circuit, prime the system if required, start the engine and inspect for leaks at operating pressure.
Use New Seals: Always fit new O-rings/seals at each connection and lubricate them lightly with clean diesel or manufacturer-recommended lubricant to ensure a proper seal. After installation, run the engine and check for leaks before road testing.
Why This Part Fails Most Often
- Age And Material Degradation: Plastic or rubber components harden and crack over many years, especially when exposed to heat cycles under the hood.
- Corrosion And Contaminants: Metal fittings and clips can corrode; debris in the fuel can damage seals and fittings leading to leaks.
- Vibration And Mechanical Stress: Incorrect routing, missing clamps, or engine/transmission movement can fatigue the pipe or its connections.
- Improper Installation: Reusing old seals or overtightening connectors can cause leaks or damage.
Signs That The Fuel Supply Pipe Needs Replacement: Visible fuel leaks, strong diesel smell in the engine bay, difficulty starting, rough idle, or fuel pooling under the vehicle. Replacing the feed pipe and all associated seals usually resolves these symptoms when they are caused by a damaged fuel line.
This part is typically searched by its product code (1607147180). Ensure the vehicle specification matches the 1.4 HDi 66 kW Delphi system when selecting this item to guarantee correct fitment.
