Aluminum Fuel Filler Neck and it works!

An aluminum fuel filler neck is one of the most essential to any vehicle's fuel configuration. It helps fill and store fuel inside the fuel tank by functioning as a valve that holds and maintains the fuel tank's pressure.

The simple fuel filler neck is critical for an engineer to work on and therefore has value when considering the design. Configuration is important as it is the main part of the power system, as opposed to any other part of the complete system.

These are some of the functions that a stainless steel filler 
neck performs:
• acts as a valve that controls the pressure of the fuel tank.
• Seals hydrocarbon vapors
• Seals the fuel and does not allow the fuel to evaporate into the air
• Controls the emission of hydrocarbon vapors into the atmosphere
• Limits pressure by venting fuel vapors when there is high pressure inside the tank.
• sucks in low pressure air

A stainless steel filler neck is designed to keep up with environmental and safety 
regulations and evolving technology.
Some of the available filler caps are:
1.
Ventilated Fuel Fill Caps - These caps feature a 
special vent valve that relieves both vacuum and 
pressure.
2. Non-Vented Fuel Tank Caps: These caps do not 
have a breathing mechanism and are used with a 
fuel tank, which is already connected.
3. Regulated Fuel Fill Plugs - These plugs feature 
regulated relief valves for controlled release of 
high pressure due to hydrocarbon vapors and 
regulated air intake to maintain specified pressure 
limit.

Before buying, check the filler caps and neck for:
• Simpler cap extension with filler neck and stainless steel
• Fine sealing tool
• High-quality material to avoid any deterioration
The stainless steel filler neck on more advanced vehicles also includes a hose connected to 
the fuel tank at one end and the filler neck at the other end, near the gas cap opening.
