Heater hose routing on 65 barracuda with AC.

Found a pic that I can finally see the routing of the heater hoses.
It appears I do have them routed correctly . it just doesn't seem right though for the high pressure side from pump go directly to the heater core first and then return line from heater core has the vac control valve in route. what do you guys think ?

Stroker402, does that control valve have two vacuum lines attached to it? Do you have a part #for it? If so, where can I get one?

thanks, easyrider
