If I go back (way back!) to my 1979 days it was pretty much the same setup but with a vertical, cylindrical filter of some sort included in the booster line. You can see it in your first pic. I do not know its purpose.

Paul, I don't remember what the big filter on the PB vacuum hose is either. I always figured it was some sort of large check-valve type of device possibly to keep gas and crankcase vapors from the carb or intake from backflowing into the PB booster unit.

I suspect so but the lack thereof has not hurt my 1974. Perhaps a problem developed afterward. Another mystery of Corvette history and design engineering I guess.

FWIW for the original poster, you can't find that steel line anywhere. But a little bit of $5.00 NAPA steel tubing and a bender/flaring tool it can be done. The brass fitting is about $2.00.

If the car is in front of you ,as you know, its a no-brainer !
One "very good" thing I've noticed for awhile now, we all seem to work nicely together , watching each others backs and correcting incorrect information "gently" to see the OP gets the information he or she needs.
That makes spending time here trying to help C3 owners a real pleasure.

Ernie when you work on different years and different engines each day like we do ,they all have a way of blending together.

unfortunately there are a few exceptions to that with some people on here... but that's the downside of public forums. There is always some bad to go with the good

One thing's for sure, the pictures and diagrams you guys got me will help out immensely. Next time... I'm not gonna pull the "newbie" mistake of taking everything apart and assuming that I'll remember how it goes back together. I'll start taking everything back apart and plugging off what I don't need (like the EGR stuff) and let you all know how it turns out.
And a million thanks to everyone for helping me out on this!!

Haha. I know I had that same thought... but sometimes my stubborn-ness gets the best of me and I think I'll be able to get away with it. Next time, I'll consider this lesson learned.
