Well first off I've searched the site, other sites and my Haynes manual. I just cannot figure this out.
Bought it with these hoses blocked off as is.
1990 3vze



This runs behind towards the back of the engine by the firewall




Do these two lines run into the intake manifold? Please see below picture




This vacuum hose goes from one outlet into the other outlet just below it.

Okay so the two in the second picture with bolts in them look like they are the Power Steering vacuum hose lines...you can remove them or leave them like this, the only thing they were originally used for was to idle up the engine if you were at full steering lock under no load...to keep it from stalling...If your pump blows a seal it can leak fluid from there and can fill your intake with PS fluid so I would just leave them plugged and you will be fine...I am actually about to go put lines back on mine and plug them for that exact reason, it is pissing fluid all over the place...

The hose in the first picture looks to be the coolant passthrough hose that goes to the backside bottom of the throttle body if you look below where your hand is and tucked back a bit basically directly beneath the plug you should find it...

and the "U" hose that is in the third picture is just plugging up vacuum lines from the intake, I can't say specifically, but that may have been where the PS lines hooked to, or something else that has been removed, I took mine off and actually removed my hard lines and plugged my remaining lines that were not in use so I can't remember for sure...

Hope that helps, if you need I can take some pictures and help you, just let me know...

No problem man, i had a problem when i was putting all my hoses back together and it took me a couple days of hard research to figure them all out for mine
