A0004707905 Mercedes-Benz Fuel Filler Cap / Sealing Cap

1.Product Introduction

This locked fuel filler cap with OE number A0004707905 is a sealing protective part for Mercedes-Benz heavy truck fuel tanks. Its function is totally different from chassis mounts and intake hoses. It is fitted at the fuel tank inlet. With an internal sealing ring, it provides reliable sealing. It comes with lock cylinder and keys for anti-leakage, anti-fuel evaporation and anti-theft purposes. Under bumpy driving and high-temperature conditions, it tightly seals the tank to avoid diesel leakage and evaporation, cutting fuel loss. It also blocks rainwater and dirt from contaminating fuel, protecting the fuel pump and injection system. Made of high-strength engineering plastic with oil-resistant rubber gasket and an anti-loss chain, it adopts original standard thread pitch for smooth screwing. It is widely used on long-haul tractors, dump trucks and mixer trucks, a regular consumable part for fleet maintenance.

5. Q&A Section

1. Q: What problems will poor sealing of the fuel filler cap cause?                                                                            A: Increased fuel evaporation loss, water and dirt entering the tank, blocked fuel lines and vehicle warning light activation.
2. Q: Is this fuel filler cap lockable with keys?                                                                                                               A: Yes. It has a built-in lock cylinder and separate keys for anti-theft function.
3. Q: Can I replace the chain separately if it breaks?                                                                                                  A: Yes. The chain is a separate accessory. You can replace it when the shell and lock cylinder remain intact.
4. Q: Can I just replace the rubber gasket if it leaks due to aging?                                                                            A: The gasket can be replaced separately. If the cap thread is not worn, a new gasket can restore sealing performance.
5. Q: Are fuel filler caps interchangeable among different Mercedes-Benz models?                                                   A: No. Always check the OE number. This A0004707905 only fits vehicles with matching tank thread specification.
