vacum port/lost my mind?
Ok, so I swapped the engine out of my 88 formy350, and into my 87 gta. It went well and everything seems to be hooked up right. All the vacum lines I have are in there place. So I do one last look around and see this port on the back of the plenum on the driver side with no hose to it. I look around and do not see a hose for it. Any Ideas what hose is suppose to go on it? I'm loseing/lost my mind trying to figure this out. Oh, the books I have do not show that port, just like the sticker on the hood. Thanks for the help.

To the fuel pressure regulator? or to the line that operates the flaps in in the heater controls?

The only port I can think of on the driver's side of the plenum is the one for the brake booster. It's all the way at the back corner and kind of angled.

twobirds, consider yourself lucky. When I bought my 82 TA I found that when the 305 engine was swaped with a 350 all the vacuum lines for the emissions had been removed, the hoses were cut short and had screws acting as corks. If anyone has any answers or better yet diagrams, i'll get back to you with the models of the parts.
