Overflow hoses Citroën Peugeot 9676245280 9676290580 1574JK

Description

Overflow pipes for 1.4 HDI and 1.6 HDI engines

Part description

Overflow hoses (overflow hoses) for Citroën/Peugeot cars are used to drain fuel overflow from the injectors back into the system. If the original hoses are brittle, cracked or leaking, you may experience a diesel smell, wet injectors and poor engine performance. This part is suitable as a replacement for a worn overflow line on the engines listed in the documents and is often searched for directly by number.

Installation recommendations

Generally/typically for injector overflow tubes, it is a job sensitive to cleanliness and correct seating of joints. The exact procedure may vary depending on the specific engine design and hose routing.

1) Before assembly

• Compare with the old part: shape of line, number and type of terminals/connectors and lengths of individual branches.
• Check the condition of the hoses: cracks, hardening, damaged ends and traces of leakage.
• Clean the area around the injectors so that dirt does not get into the joints during work.

2) Necessary tools and materials (in general)

• Gloves, towels / absorbent material
• Appropriate clip pliers (if used), small flat tools to carefully loosen joints
• Degreasing cleaner to check for possible leaks after assembly

3) Step-by-step assembly procedure

1. Turn off the ignition and let the engine cool down.
2. Ensure access to the overflow tubes (depending on the design, it may be necessary to remove the covers).
3. Clean around the connections so that dirt does not fall into the connection points when disconnecting.
4. Line the work area with absorbent material (a small amount of fuel may escape).
5. Carefully loosen the ends/clips and remove the old overflow tubes from the individual connections.
6. Check the seating areas (cracks, remnants of old material, deformations) and clean everything.
7. Put the new overflow tubes in the same line as the original, without crossing or straining.
8. Push the ends as far as they will go and secure the clips/joints so that the joint is tight, but the tubing is not under unnecessary stress.
9. Check that the hose does not rub against sharp edges anywhere and is not in contact with very hot parts.
10. Put back the removed covers and check that the hose lines remain properly seated.

• 4) Post-assembly checks and function verification

  • After starting, check all connections visually and by touch for moisture/fuel leakage.
  • After a short test drive, check again, especially at the points of connection to the injectors.

  5) The most common assembly mistakes + how to avoid them

  • Incorrect seating of the end cap → always push to the stop and check the strength of the connection.
  • Swapping hose routing/tensioning → route the hoses the same way as the original, without pulling and twisting.
  • Dirt in the joints → carefully clean the surroundings before disconnection and assembly.
  • Damage to the ends during disassembly → release carefully, do not use brute force.

  Reasons why the part is damaged

  • Aging of the material (hardening, embrittlement of hoses and ends).
  • Thermal stress in the engine compartment and repeated temperature cycles.
  • Fuel leakage which gradually worsens the tightness and can “wash out” the joint.
  • Motor vibration and mechanical stress on the line (tension, kinking).
  • Incompetent handling during previous disassembly (damage to terminals/clips).
