A fuel system that in at least some implementations includes a carburetor having a fluid passage, a solenoid, a valve, a driver circuit and a control circuit. The valve may be moved by the solenoid between an open position permitting fluid flow through the fluid passage and a closed position at least partially inhibiting fluid flow through the fluid passage. The driver circuit and control circuit are communicated with the solenoid to contribute to providing power to the solenoid and controlling actuation of the solenoid. The driver circuit and control circuit provide a first magnitude of power to the solenoid to initially change the solenoid from its closed position to its open position and a second magnitude of power to maintain the solenoid in its open position wherein the second magnitude of power is less than the first magnitude.

A protective cover assembly for a fuel pump in a motor vehicle includes a hooded cover having a first face and a second face in addition to distal and proximate stud bolts, and a base fastener. The hooded cover defines a plurality of apertures operatively configured to receive a corresponding fastener. The distal stud bolt may be operatively configured to affix a distal end of the hooded cover to a cam carrier. The proximate stud bolt may be operatively configured to affix a middle region of the hooded cover to the cam carrier while the base fastener may be operatively configured to affix a lower portion of the hooded cover to the cam carrier. The proximate stud bolt includes an outer diameter feature which is operatively configured to engage with a plunger region of the pump assembly when the proximate cover assembly is subjected to a load.
