After finishing the installation of the Subaru-Brat water pump on my H-Mod, SIAM-Fibersport, I was asked for the sketches I used to fabricate. So I went on a massive hunt on where I got these sketches and best I can figure was a 2007 Post in the now defunct Yahoo Groups H-Mod forum that Nat Sherrill, Marty Stein and others managed. Best I can tell is that Marty and Franklin Rudolph were involved in posting these sketches. If I learn otherwise I will correct.
So along with pictures of my installation on here are the sketches I used.
Good luck and share your completed photos.
