I noticed I have multiple vacuum hoses that are cracked or disconnected, I am doing a little tune up tomorrow and might as well get the hoses replaced. I am wondering exactly which hoses to keep connected. I was planning to keep PCV and the Dizzy vac retard and cap everything else. I am going to be getting rid of the EGR and EVAP equipment and see no use in replacing their hoses.

LMK how this goes. I want to start taking off emission equipment and didn't want to have car running poorly. Thanks.

I've removed most connections as you were saying, but I kept the purge canister hooked up to vent the fuel tank.
So I have PB booster, dist (direct to carb), PCV, and canister. Also, don't forget vacuum to your heater/AC actuator. It goes into the firewall. Yours is older than mine, it may be cables(?).
