Thanks, I missed that page when searching and kept coming up with stuff that only showed the i.d.
You page confirmed that I have 3/4 and 1 inch pipe and no 1-1/4 pipe. I also was able to confirm today that my meter is only capable of 250,000/BTU /HR unless it is upgraded.
So I learned alot of useful information today. I was able to buy a number of the correct fittings (hopefully I got all the correct ones) this evening for the corrections to and the additions to my black iron natural gas piping system.
