How to Maintain a Petrol Fuel Tank

Store equipment equipped with a petroleum fuel tank in a cool, well-ventilated area, avoiding prolonged exposure to direct sunlight to minimize heat absorption by the tank and the resulting increase in internal fuel temperature.

If the tank will be used outdoors for extended periods, install a heat-insulating cover or reflective film to block heat transfer and lower the internal tank temperature.

Also, avoid placing the tank near high-temperature components such as the engine exhaust pipe and radiator to prevent localized overheating and potential safety hazards.

In hot weather, avoid leaving the tank full to prevent the fuel from expanding and overflowing due to temperature rise.

Also, avoid leaving the tank empty for extended periods to minimize accelerated oxidation and corrosion of the internal fuel tank due to a lack of fuel protection.

Choose reputable gas stations to refill with gasoline that meets applicable standards. Low-quality gasoline can easily evaporate at high temperatures, forming a colloid that can adhere to the tank walls or clog pipes.

If the fuel has been stored for an extended period, regularly check the fuel and replace it immediately if any signs of deterioration are detected to prevent any adverse effects on the internal tank environment.

High temperatures accelerate the aging of fuel tank seals and joint rubber rings. Regularly inspect the fuel tank's filler port seals and pipe joint seals.

If hardening, cracking, or leakage is detected, replace them with suitable new seals immediately to prevent fuel volatilization or leakage due to seal failure.

Also, check the fuel tank's vent holes to ensure they are unobstructed and unblocked. This prevents elevated internal pressure from failing to release at high temperatures, potentially leading to deformation or fuel overflow.

Ensure pressure balance inside and outside the tank.

Regularly clean the exterior of the fuel tank from dust and oil. These debris adhere to the tank surface, hindering heat dissipation and causing localized overheating.

If the tank is made of metal, inspect the surface for signs of rust. If found, promptly repair with anti-rust paint to prevent corrosion exacerbated by high temperature and humidity.

During daily use, monitor the fuel tank for any unusual noises or signs of leakage. If the equipment experiences a strong fuel odor or an abnormally low oil level during operation, immediately shut down the machine for inspection to eliminate any safety hazards.
