I still cant fathom how fuel can come out of where you describe. Are you sure that there is not a leak in a fuel line near injector #4 which is in close proximity to the air cleaner hose?. Did you pull the hose off the valve cover? Does fuel still come shooting out without the hose? What you describe seems impossible to me.
If the fuel distributor was leaking, the fuel would go down the intake manufold and be burned. Pull the right side valve cover and have a look inside. If fuel is comming from inside the valve cover you might get a clue.
What was causing the major vacuum leak?
