Guys, I am trying to fab up a snorkel similar to the Mantec. What I need is the exact Outside Diameter (not circumfrence) of the actual pipe. Sorry to be a pain but try and get as specific as possible. I found a couple of other threads about homemade versions and they all used 3" thin walled tubing. Well, I just I bought some 3" tubing with an O.D. of exactly 3" and it looks pretty damn big just sitting there. I don't want to get well into fabrication and realize I should have used a different diameter. Thanks for the help. DII. Yes, I will post pics when finished
