2000 manifold upgrade:removing barbed fitting?

I am doing the 2000 manifold upgrade along with swapping a 96 engine into my 92 cherokee. I need to remove the barbed fitting on the 2000 intake manifold that is closest to the firewall because it is to big for any of the hoses i need to hook up. my question is,is this a screw in fitting,or is it pressed in,in which case I will just have to plug it and have to use a tee for the other hoses i need? I tried to get it loose with a pair of vise grips,but was afraid of twisting it to much and breaking it off. thanks for any help!! Ben

thanks,Ten high. I got all the vacuum hoses hooked up this morning. i did plug the one in question,and just used a 3 way tee to get the other hoses hooked up to the manifold.
