You probably have a 1/8" NPT thermocouple, but there are 1/4" NPT ones. If it is 1/8" you will need a size R drill and a 1/8" NPT tap. The 1/4" requires a 7/16" bit and a 1/4" NPT tap. What is the part number on the thermocouple?

bpollard1248, welcome to DTR !!!
It seems you missed getting the single most important guage you can have. A fuel pressure guage will likely end up saving you a lot of money. Do a search and a little reading.

I have had experience with all three, and I really like my DiPricols the best. Their wiring harnesses are smaller and easier to route. They look better, IMHO, and they are very high quality. They are a little pricey, and they don't have a large variety of OPTIX series gauges for other needs, like oil pressure, etc.
