So if I'm reading this correctly, you are actually getting coolant by the cap, not just out the hose? 1st I would check to see if the hose is bad and leaking on to the tank during a purge. If not you may have a cracked cap or its just not sealing well, so I would go and replace it. May just be that simple of a fix.
When mine got real bad I rerouted the hose into a soda bottle so I could keep track of when and if it purged and it also helped to recycle the coolant so I was not constantly buying more.
