Default Leaking gas out of vaccum line why and how don't make sense to me but it's a 1995 CBR

I just got an 1995 cbr600 it's rough shape and sat long time I got it running but fuel pump doesn't come on unless I wire it direct and weather I use pump or gravity feed the bike leaks gas out of vaccum line the one big one that runs along side air box up to front this makes no sense to at all how is fuel getting into vac line I'd like to do away with all things not absolutely needed with vaccum does any one have simple diagram that will show me mine is a 1995 600

so ah.. what part sends power to fuel pump?

Do you have CA or 49-state model?

Trace where vacuum line with petrol dripping out goes. Where does upper end connect?

If it has a vacuum operated pet **** the diaphragm is busted allowing fuel to get into the vacuum lines .
