Sailman 1,134 #1 Posted March 9 I am just about completed with the 704 but the fuel tank is leaking from the shut off valve. The valve is attached to the metal tank so I can't replace it without serious cutting the tank. I have taken it apart and appears there should be an o ring. Any idea what size o ring? Is a replacement part available that replaces just the part pictured (not the body that attaches to the tank). Share this post Link to post Share on other sites
