I have TroyBilt TB30R (13B226JD066 (2015) rear engine mower. I've it for about 9 years. The fuel tank vent lines (2 lines) are running from the top fitting above the carberator toward the fuel tank. Anyone have any experience in removing the top fender/cowl to expose the fuel tank? A diagram would be nice but I can settle with instructions or a video. I checked YouTube but got nothing. Thanks in advance.
