Brake Servo

Please can someone point out the vacuum hose and control rods.

its the rubber hose connected to servo and engine,what control rods

My manual references them but I couldn't find anything that I thought could be them

The photo of my diesel shows the vacuum pipes from servo to to the vacuum reservoir bottle just infront of water reservoir bottle , there is a Tee connector with another pipe going to the underside of the inlet manifold where the vacuum is . On the rhs of the the inlet manifold there is a control rod which controls the butterfly valve inside , this needs to be set correctly otherwise servo and brakes won’t work well is this the one you need , I don’t think this is on the petrol

Thanks
