sealing should be fairly easy (and permanent) with PVC glue
just need to make sure that when you start screwing the pvc barb in you go quickly and don't stop because once it stops, it's going to stay there forever

Without seenig a more clear picture here is what I can say. If you tap the holes again you have to make them bigger and move up to 3/8" NPT fittings, but you should not have to do that.

You should just be able to take epoxy or silicone, coat the threads and you are in business again. And like the other posts say it will be permenant.

If you really need to tap the holes again you will have to determine how big you want your threaded hole to be hole to be, drill it with a drill bit that is a little smaller than the hole and tap it with the approperate tap. IE for 3/8" npt treaded hole you would have to drill out the hole to about 7/16" and then tap it.

Remember that a 3/8" NPT threaded hole IS NOT 3/8" diameter, it is larger.

As for the actual hole you would have to drill I don't have that information on hand.

I agree.

depending on the barbs and threads, I typically use 1/4"NPT threads wich is close to 1/2" OD. It uses a 7/16" drill and a 1/4"npt tap. If you are tapping plastic, be extremely careful, it likes to crack easily, in 1/2 turn out 1/4.

and I suggest using CRC lubricant. It works great w/what JFettig advises.
