Fuel tanks and filler pipes

Fuel tanks and filler pipes are key components of the fuel system, ensuring the safe storage and transport of fuel to the engine. Their proper design and maintenance are essential for trouble-free vehicle operation and environmental protection. At Global Parts, you'll find a wide selection of used car parts, including fuel tanks and filler pipes, ideal for BMW , Audi , Mercedes , Volkswagen , Mini , and more .

What are the functions of fuel tanks and filler pipes ?

Fuel tanks and filler pipes play a key role in the fuel supply system:

• Fuel tanks – Store fuel in a safe environment, protecting it from leaks and contamination.
• Fuel Filler Tubes – Enable easy and safe refueling by ensuring a quick flow of fuel into the tank.
• Gaskets and breathers – Ensure the tightness of the system, preventing leaks and the emission of fuel vapors. These elements must be made of durable materials that are resistant to fuels, corrosion and extreme weather conditions.

Construction and materials used in fuel filler pipes

Fuel filler pipes are typically made of galvanized steel or plastics resistant to gasoline and diesel fuel. Premium cars, such as the Mercedes B-Class W245, use pipes with an additional corrosion protection layer and a seal at the connection to the tank. The Mercedes W245 fuel filler pipe has an internal diameter of approximately 45 mm and a length adapted to the body geometry (approximately 1.2 m).

Why is it worth taking care of fuel tanks and filler pipes ?

Damage or wear to fuel tanks and filler pipes can lead to problems such as:

• Fuel leak – A safety hazard and fuel loss.
• Fuel contamination – Dirt or moisture entering the tank can damage the fuel system and engine.
• Problems when refueling – Damaged fuel filler pipes can make filling the tank difficult. At Global Parts, we offer original used fuel tanks and filler pipes that have been thoroughly tested to ensure their durability and tightness.

Table: Typical symptoms and parameters of fuel filler pipes

Symptom / feature	Possible cause	Technical parameter / note
Difficulty refueling	Blockage or kink in the pipe	Nominal diameter 40–50 mm
Smell of fuel in the rear wheel arch area	Microcrack or leak	EPDM O-ring seal
Leaks during refueling	Damaged tank clamp or nozzle	System operating pressure < 0.3 bar
Improper tank venting	Clogged vent pipe	Vent channel with a diameter of 8–10 mm

How to choose the right tanks and fuel filler pipes ?

When selecting fuel tanks and filler pipes, there are several key aspects to consider:

• Vehicle-specific fit – Every fuel system has its own specific technical requirements. At Global Parts, you'll find fuel tanks and filler pipes perfectly suited to BMW , Audi , Mercedes , Volkswagen , Mini , and more .
• Technical condition – Make sure parts are free from cracks, corrosion and other damage.
• Fuel Type – Choose tanks and pipes compatible with the type of fuel used in your vehicle (petrol, diesel, LPG).

Compatibility and fit

Fuel tanks and filler pipes vary in design, even within a single car model, depending on the year of manufacture, engine version, and fuel type. For example, the Mercedes B-Class W245 fuel filler pipe is available in several variants: for the B150/B170 petrol versions and for the B180 CDI/B200 CDI diesel engines. These components are not interchangeable, so selecting them by VIN or OEM code is the most effective way to verify.

Benefits of proper part fit

A properly selected fuel filler pipe guarantees:

• Cost savings associated with avoiding leaks and fuel losses.
• Safe use thanks to tight connections.
• Compliance with emission standards, which is especially important in newer vehicles meeting Euro 5 and Euro 6 standards.
• Hassle-free installation – geometric fit eliminates the need for modifications.

Why choose used fuel tanks and filler pipes ?

Used car parts , such as fuel tanks and filler pipes, are a practical solution that allows you to save money while maintaining high quality. By choosing used fuel tanks and filler pipes, you gain:

• Lower costs – Used items are much cheaper than new ones, but offer just as high quality.
• Ecology – Recycling car parts supports environmental protection and reduces waste.
• A wide range – In our store you will find fuel tanks and filler pipes for the most popular car brands.

How to take care of fuel tanks and filler pipes ?

To ensure that fuel tanks and filler pipes function reliably for a long time, it is worth following a few rules:

• Regularly check the system for leaks to prevent fuel leaks.
• Keep your fuel tank clean to avoid contaminants entering the fuel system.
• Check the condition of seals and vents to maintain complete tightness of the system. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full functionality of your power supply system.

FAQ - Frequently asked questions about fuel tanks and filler pipes

Question	Answer
What is the fuel filler pipe for?	This hose connects the fuel filler neck to the main tank. It allows for quick and safe filling without fuel loss or fume emissions.
What is the difference between a fuel filler pipe and a vent pipe?	The filler pipe allows fuel to flow, while the vent pipe removes air and vapors from inside the tank during refueling.
What does OEM fit mean in the context of fuel filler pipes?	OEM fit means that the part complies with the original manufacturer's specifications – both in terms of dimensions and material.
What symptoms may indicate damage to the fuel filler pipe?	The smell of fuel in the wheel arch area, difficulty refueling or leaks are the most common symptoms of wear or leaks.
Does the Mercedes W245 fuel filler pipe fit other Mercedes models?	Not entirely – pipe construction varies, including in terms of angle and nozzle diameter. Matching by VIN is recommended.
How long does it take to replace a fuel filler pipe?	An experienced mechanic can perform the replacement in 60-90 minutes, depending on the vehicle design and access to the tank.
