I am seeing many things. I bought the kit from Diesel Manor which are the Di Pricol Optix series. What size drill bit and tap do i need to use??? Thanks, Jason

 

Call DM and ask them. They were helpful on the phone. I got the Isspros from them so I don't know if you got the same thermocouple or not.

 

Do a search, more info there than god has

Also we don't know what size thread your gauges has. If it's 1/8" NPT then you need a 1/8" Tap, if it's 1/4" then you need a 1/4" Tap. Also the taps will decide what size drill you use.

Let us know what size it is, and we'll help you

 

I think my Edge pyro used a 5/16" bit and a 1/8"NPT tap. Optimum size bit was a 21/64

 

You are correct Sir!

 

i e-mailed DM...ive searched but i guess i wasnt fully understanding what was being said...i think i have it figured out now tho..thanks guys..

 

My outlook pyro used a 5/16" bit with 1/8NPT tap.

 

5/16 for 1/8"NPT 7/16" for 1/4" NPT

 

Best bet is to look at the side of the tap. A quality tap will tell you what size pilot hole to drill. It is usually a 1/64 or 1/32" number. The standard size bit will work but using the correct pilot hole helps reduce the chance of a leak. Dont forget to put a little antisieze on the threads before inserting your new pyro incase you need to pull it one day.
