A fuel system for an aircraft, the fuel system comprising: a main pump that receives fuel from a source ; a servo pump that receives fuel from the source ; a servo minimum pressure valve , wherein the valve is configured to receive fuel from the main pump supplied through a first line and to receive fuel from the servo pump supplied through a second line ; and a servo pump bypass connection element connecting the first line and the second line , characterised in that the servo pump bypass connection element is configured to allow fuel to bypass the servo minimum pressure valve and flow directly between the first and second lines depending on the pressure of the fuel within each line, such that in use, when the pressure of the fuel circulated from the main pump is greater than the pressure of the fuel circulated from the servo pump , a portion of the fuel from main pump is routed through the servo pump bypass connection element to the second line , and when the pressure of the fuel circulated from the servo pump is greater than that of fuel circulated from the main pump , a portion of the fuel from the servo pump is routed through the servo pump bypass connection element to the first line to join the flow of fuel from the main pump . a main pump that receives fuel from a source ; a servo pump that receives fuel from the source ; a servo minimum pressure valve , wherein the valve is configured to receive fuel from the main pump supplied through a first line and to receive fuel from the servo pump supplied through a second line ; and a servo pump bypass connection element connecting the first line and the second line , characterised in that the servo pump bypass connection element is configured to allow fuel to bypass the servo minimum pressure valve and flow directly between the first and second lines depending on the pressure of the fuel within each line, such that in use, when the pressure of the fuel circulated from the main pump is greater than the pressure of the fuel circulated from the servo pump , a portion of the fuel from main pump is routed through the servo pump bypass connection element to the second line , and when the pressure of the fuel circulated from the servo pump is greater than that of fuel circulated from the main pump , a portion of the fuel from the servo pump is routed through the servo pump bypass connection element to the first line to join the flow of fuel from the main pump . the second line , characterised in that the servo pump bypass connection element is configured to allow fuel to bypass the servo minimum pressure valve and flow directly between the first and second lines depending on the pressure of the fuel within each line, such that in use, when the pressure of the fuel circulated from the main pump is greater than the pressure of the fuel circulated from the servo pump , a portion of the fuel from main pump is routed through the servo pump bypass connection element to the second line , and when the pressure of the fuel circulated from the servo pump is greater than that of fuel circulated from the main pump , a portion of the fuel from the servo pump is routed through the servo pump bypass connection element to the first line to join the flow of fuel from the main pump . <EOS>
