The Fuel Filler Neck Housing 9819749980 is an OEM‑style replacement designed for a range of Stellantis passenger and light commercial vehicles. This sturdy housing secures the fuel filler neck and cap assembly, guides the fuel nozzle during refuelling and helps seal the tank inlet against dirt and moisture. Commonly referenced under part numbers 9819749980, 9819748880, 9819749680 and 9819748780, this unit is suitable for Citroën Berlingo K9, Peugeot Rifter, Fiat Doblo III, Opel Combo E K9 and Toyota ProAce City models. Clear labelling of the product codes makes it easy to find the correct part when searching by reference number.
Function And Benefits
The filler neck housing forms the visible outer structure around the fuel filler cap and acts as the mounting point for the filler neck tube and flap. It ensures correct alignment of the pump nozzle during refuelling, supports the locking mechanism of the fuel cap, and contributes to a tight seal that prevents fuel vapour escape and water ingress. Built from durable materials, it resists road debris and chemical exposure while keeping the fuel inlet accessible and secure.
How The Part Fails And Typical Service Life
Under normal driving conditions the housing is a long‑life component, but it can fail prematurely due to impact damage (parking bumps, side impacts), sustained exposure to UV and harsh chemicals which can make plastic brittle, or damage to the mounting points and clips. Water ingress, corrosion of surrounding metal brackets and degradation of rubber seals may also lead to poor sealing and fuel odours. Lifespan depends on usage and environment; inspect the housing during bodywork or fuel system service for cracks, broken clips or deformed seals.
Replacement Procedure (Practical Guide)
Basic replacement can be performed in a workshop or by a competent DIY mechanic. Typical steps:
- Open Fuel Flap And Remove Cap: Ensure the vehicle is switched off and in a safe, ventilated area.
- Access Mounting Fasteners: Remove interior trim or access panel in the wheel arch or luggage compartment as required to reach screws, bolts or clips securing the housing.
- Disconnect Filler Neck Hose: Loosen clamps and carefully separate the filler neck hose from the tank inlet. Take care to support the neck to avoid damage.
- Remove Old Housing: Unclip or unscrew the housing from the body, noting the location of retaining clips and seals.
- Install New Housing: Fit new seals if provided, align the housing, secure fasteners and reconnect the filler neck hose with appropriate clamps.
- Check Operation: Close and open the fuel flap, verify cap engagement and inspect for leaks or misalignment. Refit interior trim panels.
Recommended Tools: Torx/Screwdriver Set, Trim Removal Tools, Hose Clamp Pliers, Protective Gloves. Observe manufacturer torque values where specified.

Installation Recommendations
Before starting work ensure the vehicle is parked on a level surface with the ignition off. Remove any clips and fasteners carefully to avoid breaking plastic trim. Replace any damaged seals or worn clips to restore correct fitment and sealing. After installation, verify that the filler cap locks and seals properly and that the fuel flap closes flush with the body. If corrosion is present on surrounding mounting points, treat and repair before fitting the new housing to ensure long‑term reliability.
Most Common Reasons For Failure
Impact Damage: Bumpers or side contacts can crack the housing or break mounting tabs. Environmental Aging: UV exposure and chemical contact can embrittle plastic. Seal Degradation: Deteriorated rubber seals allow vapour escape and water entry. Mechanical Wear: Repeated forcing of the fuel nozzle or improper refuelling technique can deform the inlet or locking components.
