I have a 5.0 HP sears chipper/shredder with a tecumseh ohh 5.0 engine on it.I have gas coming out from under the gas tank so I would assume it is the gas tank since I have already replaced the gas lines due to the lines being rotted. I need to take the gas tank off to check for a leak but can't figure out how the thing comes off the engine. From what I can tell it is a part# 36863 Tecumseh gas tank the one that is L shaped. Does anyone know where I can find some instructions to tell me how it comes off the engine.
