Crap! heater quick connect broke on vortec

Well, here is Tuesday morning, I have till thursday night to get my dually going. I decide it would be a good time to switch out the leaky quick connect for the heater, from the intake manifold and it brakes off into the intake manifold. Anyone got a trick for getting out the rest of the threads? I may just have to drill it out and retap it.
Well its 7:45am, just got back from teh shop, time to take a nap. LOL

good luck with that bro

45/64 drill bit and a 1/2-14 pipe thread tap....Works like a champ every tme

Worked great! Thanks. 3 days, 20 plus hours to get it driving. no problem. LOL See yall at THW, i'll be in the bedless crew cab chevy dually with a blue roof. LOL (didn't finish getting it painted all the way.
