Joel,
I would try a temporary repair if it were mine. If you have a Oring which is close put it on and then wrap the threads and Oring with teflon tape. Make sure the teflon tape doesn't extend below the threads, to make sure the teflon tape doesn't get into the system. Then tighten the plug good and tight. The worst that could happen is it still leaks. I've done this a few times and it worked well.
