OK. Still trying to figure out hose hoses on my intake of my 87 GL AWD Wagon with the freakin Hitachi carb. I can't find an FSM to purchase or download.. the diagrams I find on here are either broken image links or of the vacuum hoses with the air cleaner off.

First off, I know I can remove most of this stuff, and probably will, but right now I just want to get it back the way it was to avoid more problems... I cannot find out what the guy circled in red is... there was only one hose attached when I got it:

My problems now are the 3 big hoses on the right side of the air cleaner (shown with black arrows, I know great color choice :rolleyes:). I've gotten different responses and of course I have a "before" photo with the hose, but can't figure out which one goes where... I think one might just stay open:

Looks to me like it could be part of your PCV system for crankcase breathing? Possibly a vacuum hose, but looks a little small... Sorry not much more help but that's where I would start..

Thanks... it definitely had the one hose attached, but the other nipple is a little too suspiciously clean to believe it is really supposed to be open, maybe a cap fell off.

The green valve is a solenoid valve - either EGR or EVAP purge solenoid.... route it accordingly. Neither are critical and you could just eliminate it and cap the components it goes to. You can run a new vacuum line from late-ported vacuum directly to the EGR valve so it will function for emissions testing. Everything else is superflous except the PCV system. Best thing you can do is install a Weber and route the PCV correctly. I have a number of threads where I have posted the correct routing including pictures.

Thanks GD.

Trust me I've learned a lot from your posts and thank you. No emissions in Florida luckily.. just looking to keep this as simplified as possible. Weber will definitely be on the list after I find out I don't need to rebuild the engine, or after I actually do rebuild it.

On a side note, just encountered recently... finally invested in a set of tap and dies.... your advise on chasing the threads for my intake manifold gasket job was priceless also :) Thanks again.

Think I got it routed correctly. Thanks everyone for your replies!
