The invention relates to a liquid/vapor separator (1) for a fuel tank for motor vehicles, comprising a housing (2) having a droplet collecting space (9) for fuel in vapor form. The housing (2) is provided with a connection cross section (4) which, in the installed position, opens into a space surrounded by a filler pipe of the motor vehicle. The liquid/vapor separator (1) comprises at least one first connection (6) for a refueling vent line of the fuel tank, said connection opening into the droplet collecting space (9), a second connection for a service vent line of the fuel tank, and a third connection (8) for a vent line leading to a fuel vapor filter. The liquid/vapor separator (1) according to the invention furthermore comprises at least one valve, which closes at least a service vent path (12) from the second connection to the fuel vapor filter during refueling of the motor vehicle, wherein the service vent path (12) is routed as a channel bypassing the droplet collecting space (9) into the connection cross section (4) of the housing (2).
