You can fix that broken coolant nipple on the intake. Cut the other one flush with the intake and drill the hole out for a 3/8 barb fitting. It should be a 9/16 drill bit. The mix some jb weld and coat the threads on the barb fitting and thread it into the intake. Once its all the way down, put a nice coat of jb weld around the new fitting. Let that cure over night and then hook it all back up the next day.
Been there, done that. Gotta get out of a pinch quickly sometimes lol. Also, just so you know, the repaired intake is still going strong today and that was done over 3 years ago.
