Where does this vacuum hose go?

[Rappo999]

Hi,
I just finished up a complete head rebuild on an X5.
Long story but there was a burnt valve.
Valve Job, Machine Head, New Head Gasket, Water Pump, Stat, etc.
Got it put back together and seem to have missed a Vacuum hose.

Does anyone know where this goes? I am stumped.
It is on the intake side.
It is the thicker of 2 hoses going to the same place. The thinner one goes into the fender area on the drivers side.

Any help will be very appreciated. Thank you in advance.

Part of the brake booster check valve hose assy? The jet valve as it is officially known. The hose at the bottom of the valve would go underneath the intake manifold center up to the valve then on the other side it go's to the brake booster check valve and a smaller vacuum hose would go to a fitting on the intake air boot
