3sgte vac/coolant lines, from/to where? Options

[6gsillyca]

Where does this vac line run to/from? The one with the phillips pointed at it. It is labelled "3" and goes from the intake manni to a metal bracket attached to the fuel rail. I'm 99% sure it attaches to a T coming from my FPR, and shoule look like the 3rd pic. Is that correct? Can I eliminate the meat bracket attached to the fuel rail, and just run vac line from intake manni to the T?










And these coolant lines run to the TB. Which one attaches to which nipple?

So the coolant there isn't a "feed" and "return" pathway through the tb?

There is, but Im not sure if the direction really matters. Ive always just hooked them back up based on how the hoses seem like they would be laid out when connected to the tb, and I never had any issues with it.

All it does is help keep your tb from freezing in the winter.
