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.
You can find it in the e-shop under the name Overflow hoses Citroën Peugeot 9676245280 9676290580 1574JK.

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
- Turn off the ignition and let the engine cool down.
- Ensure access to the overflow tubes (depending on the design, it may be necessary to remove the covers).
- Clean around the connections so that dirt does not fall into the connection points when disconnecting.
- Line the work area with absorbent material (a small amount of fuel may escape).
- Carefully loosen the ends/clips and remove the old overflow tubes from the individual connections.
- Check the seating areas (cracks, remnants of old material, deformations) and clean everything.
- Put the new overflow tubes in the same line as the original, without crossing or straining.
- 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.
- Check that the hose does not rub against sharp edges anywhere and is not in contact with very hot parts.
- 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).
