I can only think of a few vac hoses on the drivers side,
one is about 1/4 in and its the one I mentioned that's for the tgv motor, it kinda just floating around.
another would be larger 3/8 maybe. and its to the brake booster. this hose goes towards the far left side near where the fuel rails hoses are.
off the TB itself there are two larger hoses, but those arent vac, they are for coolant
and then as sorrowfull said, the BPV hoses is often tapped for a pressure gauge.
