1976 charcoal canister hose routing to carter 0- 2543 carburetor

thanks

so what is the function of the this float bowl valve from the canister?? is it reasonable to just block it off at the canister? and would things work as intended




I know this sounds like a very basic question but i just received a purge valve ( its a cp 104) and it will be going to be teed into the PCV valve line . I would assume this will go in down stream of the canister. the valve has the two lines one is marked tank and the other can. the third smaller line is vacuum. the question does it matter in what direction it is installed in the line??
