1) The 1 inch hose on top of the engine that runs into the intake manifold.

2) The 2 inch size box with 2 tiny hose connected (one is a vacuum), that situated in front of the battery.

Thanks

Thanks. But I am quite serious to know what 2) is as one of the connector seems soaked and expanded. I may replace it if it is a critical component.

Yal guessed right on #1. The thing in the middle of the hose is a non-return valve to maintain vacuum in the booster drum, which helps maintain braking assistance in case the engine shuts off.
Perhaps a better picture would help identify #2.
