Noticed that while there can be used the 4-way brass connector (and steel lines) on the PCV instalation, some of you use rubber hoses and 'T' connectors in the vacuum system instead. Is there any practical difference between those?

Can you advise where can I get the 4-way brass connector for this installation?

I also noticed that I will need the brass connector from the PCV valve (on the picture). What type it is and any idea where to get one?

And a last one - for this brass connector will I need the '63 type of PCV valve or the '66 one? I guess the '63 one with the threading, correct?

well I got the stub of my draft tube out of my intake and compared it to a rubber grommet for a pcv valve to fit a chrome valve cover was a snug fit in the intake applied gasket sealer around the grommet and stuck it in the intake tomorrow going to buy a pcv valve for a mid 70's gm and stick it in the grommint and plumb it to the base of my edelbrock carb no muss no fuss no trying to find parts from other cars easy breezy japeneesy

The valve type will depend on how you plan to route the vacuum hose from the rear of the intake into the vacuum signal source. The photo you show has the earlier style (thread in) valve.

As for the fitting, that is going to take some research.

OK, got it. What about the 4-way brass connector - is it commonly available?

Do you have the original 3-way fitting? Can you supply a close-up photo and line fitting(s) sizes?

Can you move that plug wire and retake?

The line running down the left side is the booster supply? The one running in front of the carb is the wiper motor supply?

Can you show detailed photos of these?

Can you put an open end wrench on the booster supply line to determine tubing size?

#1 - goes to ??? (0,275 in.)
#2 - goes to driver's side firewall (0,354 in.)
#3 - goes to oposite side firewall (0,275 in.)

#1 goes to the vacuum (fuel) pump

#2 goes to the booster

#3 goes to the wiper motor

You know what I would do to keep it simple? I would insert a TEE in the flexible vacuum line just off the steel supply line (#2) supplying the booster.

If 3/8", the PCV line should be 1/2". Just buy a stepped TEE, either brass or nylon. It will keep the install clean and it can be returned to OEM easily.
