A lawnmower fuel pump operates by creating a vacuum that draws fuel from the tank to the engine. It typically uses a diaphragm mechanism that flexes with changes in pressure, allowing fuel to flow through a one-way valve into the carburetor. As the engine runs, the pump continues to maintain the necessary fuel supply to ensure smooth operation. This mechanism is crucial for engines that do not rely on gravity to feed fuel.

Why does my oil come out of my fuel pump on my riding lawnmower?
If oil is coming out of the fuel pump on your riding lawnmower, it could be due to a few reasons. One common cause is a faulty fuel pump, which may have internal damage or wear that allows oil to leak. Another possibility is an overfilled crankcase, causing excess pressure that pushes oil into the fuel system. Lastly, a damaged or worn gasket seal could also lead to oil leaking from the engine into the fuel pump.
