I told you wrong- it will run lean which is BAD. Do not drive it to McDonalds.
You can drill your discharge tube after the MAF and tap it to pipe threads and screw in a hose barb if you think it is thick enough. I would go 3/8 NPT to a similarly sized hose and then get one of those barb to barb adapters from the parts store and step it up to 3/4 or whatever the IAC takes. Of course you will take the tube off to do this- lots of metal shavings will be made that do not belong in your engine. I'd use a sealant on the hose barb to discharge but I'm not sure which. Teflon paste or maybe better- silicone? Also be sure that you *do not* over torque the hose barb or you *will* strip the threads you just cut. If you find a hose barb made of the same material as your discharge pipe, you can just have it welded up when you find someone- after you clean the silicone off of course. Hose clamps would be cheap insurance also.
