The stainless steel
filler neck is one of the most important parts of any vehicle's fuel
system. It helps to fill and store fuel inside the fuel tank by acting like a
pressure release and retaining valve in the fuel tank.
A simple fuel filler is important to the engineer and
therefore important in the design. The configuration is important because it is
the main part of the fuel system, unlike any other part of the entire system.
Here are some of the functions that a stainless steel filler
neck serves:
• Acts as a pressure control valve in the fuel tank.
• Separates hydrocarbon vapors
• Seals the fuel and prevents it from evaporating into the
air
• Controls the release of hydrocarbon vapors into the
atmosphere
• Regulates the pressure by releasing fuel vapor when there
is high pressure inside the tank.
• Draws air at low pressure
Stainless steel filler is designed to meet safety,
environmental and changing technology requirements.
Some filler caps available:
A. Vented Fuel Tank Caps: These caps are fitted with a
special vent valve that relieves both vacuum and pressure.
B. Non-Vented Fuel Tank Caps: These caps do not have a
breather mechanism and are used with an already attached fuel tank.
Adjustable Fuel Tank Caps: These caps have adjustable
breathers for controlled release of high pressure due to hydrocarbon vapors and
adjustable air intake to maintain a certain pressure range.
Before buying, check the filler neck and neck, in which:
• Easy cap extension with filler neck and stainless steel.
• Tapered Sealing Equipment
• High-quality material to avoid wear
The stainless steel filler on most modern vehicles includes
a tube attached to the fuel tank at one end and a filler neck at the other end,
next to the gas tank cap opening.
