I have a 2003 JD X485, 25HP Kawasaki fuel injected engine. Was running it yesterday and fuel started pouring out of the throttle body. I took the air filter and air duct off and when I turn on the key (engine not running), fuel literally sprays out of the throttle body. I have attached a picture with a pen pointing to the exact location of the leak, it's right at the seam where 2 pieces bolt together. Is there an O-ring in there? Also, there's 3 hoses hooked up to the throttle body, they all look like fuel hoses but only 1 on them runs thru a fuel filter. Is this correct?
