My Clarke tank just came in for my 350x and its almost 1/2? to narrow at the front mounts and almost that much too narrow at the rear also. It says in the instructions if its too tight to shut off petcock and blow compressed air into the tank through the cap. ARE YOU SERIOUS??? Who has a Clark tank on their 350x and did you have the same issues? I dont have air at home and its too difficult to load up and take it somewhere else to work on it. Im going to try a hair dryer but Im sure that wont work
