Hi, I'm in the process of restoring an 87 GT, and turning it into a 92 in the process. I've been taking pictures all along the way for wire routing and such like that but over-looked some vacuum hoses. I was wondering if somebody could help me out. I don't know where the vacuum hoses from the bottom of the plenum (upper intake manifold) go. I know there's the one hose underneath that just goes from one fitting to the other on the bottom, then there's one that's got a plug over top of it but the other's im not sure about fore i lost the hoses :\ I can take some pictures if you need them, my batteries for my camera are just dead right now so I can't. Any help would be greatly appreciated. Thanks!

Can anybody help me out...?

hey do you mean the one that is on the bottom of the upper intake that goes to the firewall, its like 3/8 inch line? if so that went to the MAP sensor, BUT BUT BUT if you are converting to mass air, that no longer goes to the map sensor, you just plug it.

The car is now a 92 so it is a MAF car. The hoses im not sure about are: the ones on the the left side of the engine, there's a pipe that branches into 3 fittings, two smaller ones, and one bigger one, and the one on the other side. If you need a better description I'll go buy a set of batteries right away and take a picture for you

is it on the backside of the intake, near the firewall under the upper?

Haha hold on, im gonna go buy some batteries, make this much less confusing, cant use my cell phone because it goes to analog a few miles out of the city... and im about 10 out so hold up :\

the ones on the left side of the car, PLASTICE lines you do not need to hook up for the car to run.

Ok here's a few.

On the first at the top on the left I have no idea where that one goes.

On the socond you see that pipe with 3 fittings that I was talking about, sits up against the firewall, I don't know where those 3 hoses go, I'm assuming the bigger one goes to the tree am I right? But the two smaller ones, no clue.

The third just shows where they sit. By the distributor is pic #1 at the firewall #2.

ok the little ones in the back, one to the smog stuff, one to the fuel pressure regulator, the one big one in the back on the vaccum tree goes to the splitter on the firewall for your brakes. the fitting on the bottom of the back of the manifold, you can plug because that went to the map sensor but no longer will because you now have mass air. the port in the front on the bottom goes to the canister infront of the smog pump. anything else?

I took out the smog pump so do I even need those? I think I do don't I? I think I remember the hoses you're talking about.. the 5 plastic ones right? they all have a common fitting on the passenger side of the car if I remember correctly which bridges to the A/C i think. The canister you're talking about is it the Charcoal canister? the big black square box below the sway bar?

Thanks a lot btw
