Vacuum line size

[UncleSaj]

Does anyone know what size the vacuum lines are that control the butterfly valve to kill the engine? in mm please, outside diameter. I have a leak and need to order some new lines but not sure what size to order. THanks!

Not sure of the size; I order that stuff from Beno.

in mm please, outside diameter.

If the hose fits over a in/outlet, it is measured by the internal diameter. Can you measure the outside diameter of what the vacuum hose fits over.
