Clinton1396 0 #1 Posted April 11, 2009 Hey I need some information on what size hardware I need to add a stack to my motor which is a 8hp Briggs. I'm going to use the plumbing elbows and piping to get it away from the hood. But I don't know what the thread size is to screw into the exhaust port, I tried searching on here but no luck. So can you help me out? Thank you Share this post Link to post Share on other sites
Brian1045 28 #2 Posted April 11, 2009 3/4" threaded plumbing pipe should be the norm for that motor. Check out this thread. (For running a stack) http://www.wheelhorseforum.com/index.php?showtopic=8741 Share this post Link to post Share on other sites
