<p>The system has a fuel tank with filler socket, a refuelling vent pipe and an operational vent pipe, connected to a common fuel vapour collection tank via a multi-path valve. A pressure compensation pipe (12) also connected to the collection tank extends over a separate break section (13) of the valve (5). This blocks the compensation pipe when in refuelling position, and switches it through when in operational position. Behind the multi-path valve, the pressure compensation pipe together with the operational vent pipe extend to the vapour collection tank via an over-run valve (14) in that vent pipe.</p> |
