The fuel pump is typically mounted on the carburetor, near the fuel tank or between the tank and carburetor. The fuel pump on a lawn mower is responsible for sending the fuel from the gas tank into the carburetor where it is needed to run the engine of the mower. When the fuel pump gets clogged or damaged, it will not allow fuel to get to the carburetor, preventing the engine from starting.
