Abstract

A fuel supply system (100) for an internal combustion engine (110) comprises a plurality of fuel injection pumps (170), each fuel injection pump (170) being configured to provide pressurized fuel to an associated fuel injector (180). A low-pressure fuel supply line (150) provides fuel from a fuel supply tank (140) to the fuel injection pumps (170). The fuel supply system (100) further comprises a low-pressure fuel return line (160) fluidly connected to the fuel injection pumps (170) and configured to return remaining fuel from the fuel injection pumps (170) to the fuel supply tank (140). The fuel supply system (100) further comprises a first fuel cut-off valve (200) disposed in the low-pressure fuel supply line (150) and configured to stop a flow of fuel from the fuel supply tank (140) to the fuel injection pumps (170).
