Connecting 'vacuum amplifier' causes hesitation off idle

lol
no smog on vehicles over 35 years old here, so I am golden

I am smelling gas now when I pull into the driveway. Can I grab canister vacuum from the EGR port? Or any other port? I would like the venting to work. But I am not hellbent on it either.

Should I use an EGR blockoff plate or is removing vacuum from the valve just as good?

much thx
