ABSTRACT:
An automobile engine driven fuel pump operates to cause alternate fuel pumping and fuel vacuum cycles in a fuel pumping chamber and concurrent alternate air vacuum and air pumping cycles respectively in an air pumping chamber and also to maintain a normally closed fuel control valve open in the fuel supply conduit to the pump during the fuel vacuum and air pumping cycles completely independently of the fuel pumping cycles. If the engine stalls, as for example in the event of a collision or automobile roll-over, the pump will stop and the control valve will close to prevent fuel leakage from the supply conduit. Pressure in the supply conduit also urges the control valve to its closed position.
