15.5 Tank valve

The tank valve is a two-way valve and has the following
features:
• Controlled opening pressure in both directions,
which prevents excess of pressure or vacuum
developing in the fuel tank and impairing engine
operation.
• Resistant to clogging with dirt.
• Resistant to icing up during winter operation.
Venting pressure 150-400 mbar. Opening pressure
under vacuum, max. 115 mbar.
CAUTION! Compressed air must not be
used for cleaning or pressure testing as
this will damage the valve components.
