Do you need to connect pvc vacuum hose to both ports on a carburetor or just one my Carter bbd has 2 ports andy old Holley 2280 had 1?

This is the Carter 2 pcv ports on the back should I contact both or does it matter if one is connected my truck dies when I let off the gas but will fire right back up it's a 83 dodge d150 318 old carb was the Holley 2280 and it had only 1 pcb port on the back

    Connect to either one and the use the right size rubber cap to block the other one. You can get the cap and any auto parts store.

    Cap off the one you are not using.
