FIELD: transportation.
SUBSTANCE: invention relates to a draining device for fuel tanks. Draining device for draining fuel from a fuel vapour system into a fuel tank comprises a port configured to be coupled to a fuel vapour accessory, and a sealing member displaceable between a closed position in which said port is closed by said sealing member, and an open position in which fuel from said fuel vapour accessory can be drained into the tank. Sealing member is displaced into said open position when pressure in the tank is substantially equal to atmospheric pressure and the fuel level in the tank is below the fuel level in said fuel vapour accessory.
EFFECT: improvement of the fuel vapour system.
