Frequently Asked Questions
How do I know if my fuel pump has stopped working?
Common signs include the engine starting but dying after 10-30 seconds, difficulty starting when warm, loss of power when mowing uphill or in thick grass, and visible fuel leaks around the pump. If your mower cranks but won't start or the engine sputters under load, disconnect the fuel line at the carburettor and crank the engine—little or no fuel flow indicates pump failure.
Does my mower need a fuel pump or does it run on gravity?
You need a fuel pump when the petrol tank sits lower than the carburettor, typically on riding mowers and some walk-behind models. If the tank is mounted above the engine and fuel flows downward naturally, that's gravity feed. Check for a small pump unit near your engine with three connections—two fuel lines and a pulse line to the crankcase confirms you have a pump-fed system.
What's the difference between mechanical and electric fuel pumps?
Mechanical pumps use engine crankcase pressure pulses to operate a flexible diaphragm, making them common on carburettor engines. They're simple, reliable, and need no electrical connection. Electric pumps run continuously from your battery and are typically found on fuel-injected mowers or models with complex fuel routing. Mechanical pumps cost less and rarely need replacement unless damaged.
Can I test my fuel pump without removing it?
Yes, disconnect the outlet line going to the carburettor and direct it into a container. Crank the engine briefly—you should see strong pulses of fuel with each turn. On mechanical pumps, also check the small pulse line from the crankcase isn't cracked or clogged. An empty fuel filter despite a full tank often indicates the pump isn't drawing fuel properly from the tank.
How long should a fuel pump last on my mower?
Quality fuel pumps typically last 5-10 years with proper maintenance. Lifespan depends heavily on fuel quality—old petrol with ethanol degrades the internal diaphragm and valves faster. Using fresh fuel with stabiliser, replacing filters annually, and draining the system before winter storage significantly extends pump life. Many pumps fail prematurely due to debris from dirty tanks rather than normal wear.
