Prater 75 #1 Posted January 10, 2012 I cant seem to find the thread that shows the washer substitute for the D-180 manifold. i need to make sure I dont have a leak through the bolt that needs the seal washer. What is a replacement that will work? Thanks in advance. Share this post Link to post Share on other sites
