Depends on the fitting size, but most of those fittings are 1/2" NPT. The drill is either 45/64" or 23/32".

Should I swap the oil pan over? I would think taping would be easier.

Also where can I something to tap the thread? NAPA? Where can I get mineral sprints to flush out the shavings inside the oil pan?

So the drill should be 45/64 or 23/32 right? Also should I tap it or swap the oil pan?

go to flyin miata's site and download their install instructions, it has the best writeup for the tap.

swapping the pans will be 1000x more work.

NAPA did not have a temp. Fuel pressure gauge to hook up to fuel rail in stock and cheapest one is $50. Also the fitting is 3/8 npt.

Have fun swapping oil pans and ignoring everything we've said. If you seriously drilled a half-inch hole in your oil pan, and you don't know where to buy paint thinner, mabye you shouldn't be attempting this.
