A fuel supply system ( 100 ) for a combustion engine ( 180 ) has at least one fuel injector ( 110 ), a fuel pump ( 130 ) and a conduit ( 150 ) connecting the fuel pump ( 130 ) with the fuel injector ( 110 ). An air intake valve ( 160 ) connects the conduit ( 150 ) to the atmosphere. The air intake valve ( 160 ) is a one-way valve that prevents sub-atmospheric pressures in the conduit ( 150 ) by allowing air to enter the conduit ( 150 ) when the pressure in the conduit ( 140 ) is lower than atmospheric pressure.
