LOCATING A FUEL LEAK IN A FUEL SYSTEM

A method for locating a fuel leak in a pressurized fuel system for a vehicle provided with a combustion engine includes: carrying out a first test to determine a fuel leak in the system including a first container and a second container that are openly connected to each other; and when a fuel leak is determined upon completion of the first test: closing the connection between the first container and the second container so as to isolate the two containers from one another; carrying out a second test for determining the presence or absence of a fuel leak in the first container; and when a fuel leak is detected upon completion of the second test, concluding a fuel leak is located in the first container or, if a fuel leak is not detected upon completion of the second test, concluding a fuel leak is located in the second container.
