Jonh Deere L120 fuel problem

Hi All,
I was wondering if someone could help me with this problem, my L120 mower isn't getting any fuel, I have replaced the fuel filter and still there is no fuel running thru it. I blew with my mouth both ways into the fuel line and it does not appear to be clogged, any ideas?
Thanks

What engine? Can you blow air into the tank from the end at the engine?

Is the fuel pump pumping, or does the fuel stop at the pump?

Well I am assuming that the fuel pump is a small roundish shaped, plastic piece that is located near the top of the motor and the fuel line runs thru. It does not appear to be pumping, it does not appear to work electrically, but by vacume maybe? Now I could also be wrong about the pump because I am not sure where it is located.

That's the pump. It works by pressure fluctuations in the engine crankcase. Take the hose off at the carb, crank the engine with the end of the hose stuck in a can, and observe to see if any fuel is flowing from the hose. If so, the pump is working. If not, either the pump is not working, or fuel is not available to the pump. (kinked line, clogged filter, tank fuel pickup not down into the fuel level, etc...).
