Abstract

A fuel system (100) for a gas turbine engine (10) includes a fuel pump (106, 114), and a fuel supply line (104) configured to supply fuel to the fuel pump (106, 114). The fuel system (100) also includes a fuel filter (108) disposed downstream of the fuel pump (106, 114). The fuel filter (108) includes a filter housing (118) and a filter media (120). The fuel filter (108) is configured to receive a flow of fuel from the fuel pump (106, 114) and to deliver filtered fuel towards a combustion chamber (16) of the gas turbine engine (10) via a fuel filter outlet (130). The fuel system (100) further includes a fuel recirculation line (110) that fluidly connects the fuel filter (108) with the fuel pump (106, 114). The fuel recirculation line (110) is configured to recirculate a portion of the fuel received by the fuel filter (108) towards the fuel pump (106, 114) based on a pressure difference between a fuel pressure in the filter housing (118) and the fuel supply line (104).
