How To Replace (Basic Guide)
Replacement of the fuel filler neck housing is a straightforward job for an experienced mechanic and can be tackled by competent DIYers with basic tools. Typical steps:
- Park on a level surface, work in a well-ventilated area and eliminate ignition sources (no smoking, open flames or sparks).
- Open the fuel flap and remove the fuel cap and any trim or screws securing the filler housing inside the filler opening.
- Disconnect any vent hoses, cap-retainer straps or sensors attached to the housing. Note hose routing and fastener locations for reassembly.
- Remove retaining screws or clips at the body mounting points and carefully extract the old housing. Some access via the wheel arch or inner trim may be required on certain models.
- Fit the new housing, ensuring all seals and gaskets are correctly seated. Reattach hoses and fasteners in the original order and secure clips/screws to manufacturer specifications where available.
- Check for correct cap seating and closure, and verify there are no fuel vapour smells or loose connections before returning the vehicle to service.
Installation Recommendations
- Inspect Seals: Replace any degraded gaskets or O-rings during fitting to ensure a tight seal.
- Hose Condition: Replace brittle or cracked vent and breather hoses to prevent future leaks or restrictions.
- Correct Fastening: Use the original type of clips or screws and avoid over-tightening plastic fasteners to prevent damage.
- Access: On some vehicles, removing the inner wheel-arch liner or rear bumper trim improves access and prevents forcing the housing into place.
- Test: After installation, verify the filler cap locks and seals correctly and perform a brief drive-by sniff test for fuel odours.
Most Common Failure Reasons
- Corrosion And Wear: Metal components and fasteners can corrode, especially in regions with road salt, leading to loosening or leaks.
- Plastic Embrittlement: Prolonged exposure to fuel vapours, heat and UV can make plastic parts brittle and prone to cracking.
- Impact Damage: External knocks to the filler flap area or improper handling during refuelling can deform or break the housing.
- Damaged Hoses Or Clips: Broken vent hoses or clips cause poor sealing, fuel smell or difficulty closing the cap.
- Poor Seal Condition: Old or compressed gaskets allow vapour escape and may trigger smell complaints or venting issues.
Why Choose This Part
If you are replacing a damaged or leaking filler inlet, choosing a housing that matches OE mounting and hose connections avoids additional bodywork and ensures reliable cap function. Searching by OE code (for example 9819749980) makes identification fast in professional workshops and parts catalogs.
Compatibility And Notes
Fits the listed Stellantis platform models above. Always compare the OE number printed on the original part with the product codes provided to confirm fitment. This component replaces the structural housing around the fuel filler inlet and is intended for direct replacement where mounting points and hose connections match.
