ABSTRACT:
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.
