Break booster check valve

[edgar7654]

im doing a motor swap on my fiances car it fires up right except i need to know witch way the break booster check valve goes the reason for this is the intake hose that connects it on the new engine is on the opposite side there for i need a 4ft hose more or less so do i blow air into the booster or into the engine i looked it up and i found two answers so which way does the air flow to the booster or the intake.... also do i need any specific hose or can i go to home depot and get a hose there?
thank you and god bless you

Install it to where it does not blow air towards the booster. The booster needs vacuum to operate.
