Claim:
1. A turbine engine fuel circuit comprising: a fuel return valve configured to be connected firstly to a main fuel circuit of a turbine engine and secondly to a fuel tank, the fuel return valve being capable of adopting an open configuration in which the fuel return valve allows an excess quantity of fuel coming from the main fuel circuit to be returned to the fuel tank, and a closed configuration in which the return of fuel to the fuel tank is blocked; a first hydraulic line connecting the fuel return valve to the main fuel circuit and including a first filter; a second hydraulic line connecting the fuel return valve to the main fuel circuit and including a second filter; and an intermediate hydraulic line connected to the first hydraulic line downstream from the first filter, and connected to the second hydraulic line downstream from the second filter, the first and second hydraulic lines being hydraulically connected together by the intermediate hydraulic line when the fuel return valve is in the closed configuration; and wherein the first and second hydraulic lines are hydraulically connected together by the intermediate hydraulic line only when the fuel return valve is in the closed configuration.
