Description / Abstract:
This SAE Recommended Practice covers design and evaluation of
the entire gasoline filler pipe assembly used on cars and light
trucks with respect to compliance with CARB (California Air
Resources Board) LEV II (meeting or exceeding EPA Tier 2 and EU
Stage-5 evaporative emissions requirements). It is limited to an
assembly which is joined to the fuel tank using either a hose,
Quick Connect Coupling, or a grommet type sealing device.
The Design Practice covers the filler cap, filler pipe, filler
pipe assembly to tank hose, and filler pipe assembly to tank
grommet or spud. It includes recommendations for design of
components and assemblies intended to perform successfully in
evaporative emission SHED (Sealed Housing for Evaporative
Determination) tests, based on best practices known at the time of
release.
