An automotive fuel system which has a fuel tank, a fuel pump, a fuel metering device for metering fuel flow to an associated fuel-consuming engine, and a fuel reservoir (such as, for example, a carburetor fuel bowl), has a valving assembly interposed generally between the outlet of the fuel pump and the fuel reservoir with such assembly being responsive to, for example, the associated vehicle experiencing a crash impact or a roll-over condition whereupon such valving assembly becomes effective to prevent the further flow of fuel from the fuel pump into the fuel reservoir.
