A fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine has a fuel pump with a pump inlet and a pump outlet, a fuel reservoir with a reservoir outlet, and a chamber connecting the pump inlet with the reservoir outlet. A reservoir supply valve between the reservoir outlet and the chamber is moved between an open position in which fuel flows from the reservoir to the chamber and a closed position in which fuel is prevented from flowing from the reservoir to the chamber, by a fuel level sender having a float arm which depresses or releases a plunger extending from the reservoir supply valve. A float attached to the float arm rises and falls with changes in fuel level within the fuel tank so as to contact the plunger and thus move the valve between the open and closed position when the tank fuel level is below and above, respectively, a predetermined level.
