Valve cover hoses and brake booster hose. (1 Viewer)

I am replacing hoses all across the motor and have found that many of them are not in the right place.

I have outlined where the hoses should be going, at least based on my research, but need some help with how its setup currently.

My brake booster does not have the vacuum on the driver side, there is 1 vacuum on the top passenger side that's it's current connected to, there are 2 more vacuum ports that are plugged on the bottom of the booster in the passenger and driver side. Should I plug the hose into the capped vacuum on the bottom by the driver's side? Or plug it back into its current brake booster vacuum on the top passenger side after I replace it and put it back in its correct location on the intake? I also dont know why my booster looks different.

2nd. I am replacing the heater control valve, and there is an open pipe next to it, that I believe the hose it suppose to go to, but instead is running down into the motor and then I lose it. Can someone explain what the pipe is and why the hose is bypassing it? And should I hook it back up. Is this a rear heater bypass hose?

EDIT: The hose coming from the HCV is a bypass hose, it has replaced the pipe and has been ran from the HCV to the block.

I have new OEM hoses for replacement.

Thank you ahead of time and happy holidays.

It looks like your brake booster is aftermarket so hard for me to tell how it should be plumbed up.
The open pipe is the PHH hardline that was left over after some one did a bypass job on it. I have attached a couple of photos of the engine bay on one of my previous trucks. It will hopefully help you get a grasp on what goes where.
Where in Orlando are you?

Yeah but you got to dock him a couple points for the GM battery.

Don't mean hijack thread but can anyone learn me what this circled port is? My 94 has a pair of vacuum hoses that attach there that I think run down to the valves underneath but not sure.

That's called a Gas Filter.

Search here for a 94 and gas filter and you'll even get part numbers.

It's a frequent question.

Indeed I see numerous threads now. I always assumed "gas filter" was "fuel filter". Thank you! Case any lost souls like me need 2-nipple 94 p/n 90917-11023.
