B20B Coolant Leak

Hey guys, I have the B20B in my 91 Integra and I used my stock B18A1 intake manifold on my new B20. There is 1 hose that comes off the F.I.T. valve that I had to block off. I have tried putting a vacuum hose plug on the fitting with 2 clamps, leaked. Then I put on a 10 inch hose with a bolt threaded in the hose and clamped, still leaked,. Next I tried putting some 60 second epoxy around the bolt and it still leaks. I waited 3 hours then started the car and it leaked. Should I put some more epoxy on and wait longer for it to cure? Its like 20 degrees here. Or does anyone else have any ideas on what I could put on that fitting?

shot you the “fix” on ht

Are you el capitan on there? If so I was asking if I could put a bolt in the fitting and put a small plug over that?
