Winter Fuel System Protection Guide

1. Freeze Protection for the Tank and Pipes

Install insulation on the tank and fuel pipelines using flame-retardant and highly insulating materials to minimize the effects of low temperatures on the fuel inside.
Wrap the pipelines with antifreeze heating tape to prevent condensation during fuel flow.
After parking, promptly close the tank vent valve to prevent cold air from entering the tank and forming condensation.
Regularly inspect the insulation for damage and repair any gaps to prevent heat loss.

Select fuel with the appropriate grade based on the lowest winter temperatures to prevent condensation from clogging the fuel lines.
Before refueling, check the fuel filter to remove any impurities and condensation to ensure fuel purity.
Observe the fuel condition during transportation. If fluidity deteriorates, immediately increase the temperature.
Avoid storing the fuel in an uninsulated environment for extended periods to minimize the risk of fuel deterioration.

Focus on the brake system to ensure the brake fluid maintains good fluidity in cold temperatures.
Ensure brake shoes are securely attached to the wheel hubs to prevent brake failure due to low temperatures.
Tires should be replaced with winter-suitable models to increase friction and prevent slipping.
Check tank welds and valve connections for cracks or loose seals caused by cold weather.
Repair any problems promptly to prevent fuel leaks.

Preheat the tank and related components before starting the vehicle, and only begin operations after the equipment reaches the appropriate temperature.
When transferring fuel, open the valve slowly to allow for a smooth flow of fuel to prevent sudden pressure changes.
After operation, completely drain any remaining fuel from the lines to prevent freezing in cold nighttime temperatures.
Clean any ice and snow from the outside of the tank to prevent increased equipment load and component damage.

Have sufficient antifreeze supplies (antifreeze, snowmelt) and heating equipment for thawing.
Maintain a safe distance between vehicles while driving, avoid sudden acceleration and braking.
If the tank or pipes are frozen, do not use an open flame to heat them directly; use warm water to slowly thaw them.
Regularly check safety devices to ensure emergency shut-off valves can operate properly in low temperatures.

Important: Always follow manufacturer recommendations and local regulations when implementing winter protection measures for fuel systems.
