you are on the right track with vacuum leak as I think it is probably from the line that fed the wipers and then a tee fed the heater control for temperature via a vacuum line.you are also going to need a piece of steel line if and when you get a dual action pump as Dave suggested and I agree on you getting one.lucky for you that valve is still working as they had a habit of leaking as the diaphragm rotted and sprung a leak.once and if you get the pump the vacuum line from intake will go to the pump as you can see by the line as is the a piece of 1/4 steel line will come from pump to rubber wiper feed line.then the line that goes on valve should follow the heater hoses and go through the firewall at point the heater hoses do.if memory serves me right there will be hole the hose will go to tee from wiper feed.that is probably where the leak you hear is coming from.if you need an idea of routing on engine side a picture of t-bird engine will show how they run much easier to find t-bird engine shots then ford.
