<p>A fuel delivery system for delivering fuel from a fuel tank (14) to an internal combustion engine has a fuel pump (38) with a pump inlet (92) and a pump outlet (46), a fuel reservoir (28) with a reservoir outlet (112), and a chamber (100) connecting the pump inlet with the reservoir outlet. A reservoir supply valve (78) between the reservoir outlet and the chamber (100) is moved between an open position in which fuel flows from the reservoir (28) to the chamber (100) and a closed position in which fuel is prevented from flowing from the reservoir (28) to the chamber (100), by a fuel level sender (56) having a float arm (62) which depresses or releases a plunger (76) extending from the reservoir supply valve (78). A float (68) attached to the float arm (62) rises and falls with changes in fuel level within the fuel tank (14) so as to contact the plunger (76) and thus move the valve (78) between the open and closed position when the tank fuel level is below and above, respectively, a predetermined level. <IMAGE></p> |
