ABSTRACT:
A fuel system for internal combustion engines which includes a fuel reservoir canister containing an electric fuel pump mounted in a fuel tank. A diaphragm-controlled valve isolates the reserve fuel from the pump inlet under normal operating conditions but a low fuel level will cause the valve to open to admit reserve fuel to the pump inlet. A float valve supplements the diaphragm controlled valve to close the reserve canister from the pump inlet when reserve fuel in the canister is near depletion.
