Hi, looking for help figuring out why my d160 is having a problem getting fuel. I just performed an oil change & oil filter, new plugs, new fuel filter & cleaned the air filter cover. When trying to start, it all of a sudden is not getting fuel to the fuel filter and obviously any further. I took off the new filter and fed hose back and tested just the gravity feed & gas was coming out. My tractor is only 3 years old and is shed kept so any help to save me trailoring it to the dealer would be greatly appreciated.
