As you can see in this picture, on the Vacuum Box, there are 4 small (black) hoses that go to each throttle body, one bigger black hose that connects to the Brake Booster on the back side of the Vacuum Box.

Where do the other 2 (Blue) Hoses connect to, and where does the (black) hose on the front of the Vacuum Box connect to?

 

You should have one to the MAP sensor, and another to the fuel pressure regulator.

 

are you referring to the 2 blue hoses?

 

Really doesn't matter what colour they are.

 

i know that. i meant to say does it matter which one goes to what. and also where does the front hose go to?

 

No it doesnt matter. Just need to get solid vaccum to all the right things.


The front one appears to be going to the bottom of the FPR.
