Solenoid Valve issues

[EEE007]

Hi as you all may be aware the D23 has a solenoid valve issue and they relocacte the valves with newer versions and longer hoses
I would like to know what size the vacuum hoses are that are connected to the solenoid vales - 3 of them , 2 look same size and 3rd is smaller , what are Inside diameters of vacuum pipes required.
I ask this as I intend to replace them with some upgraded Solenoid valves and silicon pipes.
