Abstract
Fuel filler conduit connected at one end with fuel reservoir for engine in automobile etc. has the free end exposed out of the body wall. When removing a cap engaging with said free end for fuel filling, fuel vapour therein is released in the atmosphere.

Angular movement of the lid actuates a valve normally closing an outlet to be open so that fuel vapour in the conduit is supplied from the outlet through a pipe to the engine.
