About to put the thermocouple in this morning. What size is the tap that i need to use? Thanks

1/8 pipe thread are what most of them are. Check before you drill

When I did mine I tapped it to 1/4 NPT then used a reducer/couple (whatever they are called) to take it down to 1/8 NPT. It was really nice not having to worry about busting the tiny 1/8th tap off in the manifold
