Description
Fuel tank cap for CITROËN and PEUGEOT vehicles
Part description
The used Citroën / Peugeot fuel tank cap with product number 1508N7 is a replacement part for replacing a damaged or missing cap. The reference materials list it for the Citroën C-Elysée and Peugeot 301 models. When selecting a part, rely primarily on the part number and check that its design matches the original part.
Replacing a damaged cap helps ensure that the filler opening is properly closed and protected from dirt. A used part is a practical repair option that avoids the need to purchase a new one. The specific design of the locking mechanism and the condition of the seal are not described in the reference materials.

Number 1508N7 is the primary identifier for finding this fuel tank cap. Before replacing it, also compare its shape, dimensions, and closing method with the existing part.
Installation recommendations
The following procedure generally applies to this type of part. The reference materials do not specify the cap’s design or how it is attached. The exact steps therefore depend on the specific vehicle model and version; follow the vehicle manufacturer’s instructions for opening and closing it.
1) Before installation
- Compare the product number, shape of the seating surface, and locking mechanism with the original cap.
- Inspect the used part for cracks, deformation, or damaged locking elements.
- If the cap includes a seal, check that it is intact, flexible, and correctly seated. Do not overlook a hardened or cracked seal.
- Inspect the filler neck. A damaged seating surface may prevent proper closure even with an undamaged cap.
2) Required tools and materials
- A clean, lint-free cloth and protective gloves.
- Depending on the design, basic hand tools for attaching the retaining strap, if applicable.
- For a locking version, the appropriate key; the reference materials do not state whether it has a lock or whether a key is included.
Replacing a cap that can be removed by hand typically does not require special tools.
3) Step-by-step installation procedure
- Park the vehicle, switch off the engine, and work in a well-ventilated area away from open flames and sources of sparks. Do not smoke.
- Access the cap as described in the vehicle owner’s manual.
- Clean the area around the filler opening so that dirt does not fall into the tank when the cap is removed.
- Carefully release the original cap according to its design. If it is locked, unlock it first; do not use force.
- If the cap has a retaining strap, release its attachment only in a manner appropriate to that design.
- Compare the removed part and the replacement side by side. If the locking mechanism or seating surfaces differ, do not proceed with installation.
- Check and carefully clean the filler neck’s seating surface. Prevent dirt or cleaning agents from entering the tank.
- If the replacement design uses a retaining strap, attach it so that it is not twisted and does not prevent the cap from closing.
- Fit and close the cap correctly according to its design and the manufacturer’s instructions. Do not try to overcome incorrect seating by applying greater force.
- Check that the cap is secured and, if applicable, check that the lock works. Close the outer flap, if the vehicle is equipped with one.
4) Checks after installation and function verification
- Test opening and closing the cap again. It must seat evenly and must not come loose on its own.
- Check that any retaining strap is not pinched and does not restrict closure.
- A test drive is not usually necessary for the replacement itself. During subsequent vehicle operation, watch for an unusual fuel odor or signs of leakage around the cap.
- If there is a leak or a strong fuel odor, do not use the vehicle until the cause has been rectified.
5) Common installation mistakes and how to avoid them
- Confusing it with a similar-looking part: compare both the number 1508N7 and the mechanical design.
- Fitting it at an angle or using excessive force: release the cap again, align it, and close it as specified.
- Dirt on the seating surface: clean the filler neck and the cap’s contact surfaces before fitting it.
- Overlooking damage to the seal or filler neck: check both sides of the connection, not just the cap.
- Using unsuitable lubricant: do not use products that the manufacturer has not specified for the mechanism and seal material in question.
Reasons why the part may become damaged
Fuel tank caps in general are most commonly damaged as a result of normal wear and improper handling. This is not a description of faults in this specific part.
- Material aging: temperature changes and prolonged exposure to the environment can make plastic brittle or cause the seal to lose flexibility.
- Forcing it open or closed: excessive force can damage the locking mechanism or the cap body.
- Dropping or impact: this can cause cracks and deformation of the seating surfaces.
- Dirt in the mechanism: dust and sand impair the operation of the cap and accelerate wear.
- Strain on the retaining strap: pulling or pinching can damage the strap attachment on versions equipped with one.
- Unsuitable chemical products: these can damage plastic or sealing components.
