Frequently Asked Questions
Can I repair a cracked plastic fuel tank or must I replace it?
Whilst plastic welding can sometimes seal small cracks, replacement is the safest option for damaged fuel tanks. Plastic petrol tanks are made from polyethylene which doesn't bond well with adhesives or epoxies, and repairs rarely last long-term. Attempting to patch a leaking tank creates fire hazards and risks further damage. New tanks are relatively affordable and guarantee reliable, leak-free operation for years.
Why does my mower run for 20 minutes then die, but restart after cooling?
This classic symptom indicates a blocked fuel cap vent. As fuel flows from the tank, a vacuum forms if air cannot enter to replace it. Remove the cap when the engine dies—if you hear a sucking sound and the mower restarts, the vent is clogged. Clean the tiny vent hole with a pin or replace the cap. Some caps have no visible hole as they vent through internal channels.
How do I clean rust and debris from inside my fuel tank?
Drain all fuel and disconnect the spark plug first. Remove loose debris with a turkey baster, then add half a cup of fresh petrol, close the cap, and shake vigorously to rinse. For metal tanks with rust, white vinegar soaked for 4-6 hours dissolves rust safely. Avoid using water as residue can cause fuel contamination. Always replace the fuel filter after cleaning the tank to prevent clogged lines.
What size fuel tank does my mower need?
Tank capacity depends on your mower type and cutting area. Walk-behind mowers typically have 0.5-1.5 litre tanks, whilst riding mowers use 3-8 litre tanks for extended runtime. Match the replacement tank to your original's mounting points and capacity. Larger tanks mean fewer refuelling stops but add weight. Check your owner's manual for the correct part number to ensure proper fit and fuel system compatibility.
Should I leave fuel in my tank over winter or drain it?
Never leave fuel sitting in the tank for more than 30 days without stabiliser. For winter storage, either add fuel stabiliser and run the engine for 5 minutes to circulate it, or drain the tank completely and run the engine until it stops. Old fuel degrades rubber components, creates varnish deposits, and causes internal tank corrosion. Fresh fuel in spring prevents starting problems and costly repairs.
