Quick Answer
You should drain the fuel from your generator before long-term storage to prevent fuel line corrosion and to reduce the risk of fuel line freeze damage during cold temperatures.
Fuel Line Corrosion Prevention
Draining the fuel from your generator is essential to prevent fuel line corrosion and to reduce the risk of fuel line freeze damage during cold temperatures. For gasoline-powered generators, it’s recommended to drain the fuel tank when the fuel level reaches 1/4 of the tank’s capacity. This will help prevent the fuel from breaking down and corroding the fuel lines. You can use a fuel siphon pump or a wet/dry vacuum to drain the fuel tank.
Fuel Line Freeze Protection
To further protect the fuel lines from freeze damage, it’s recommended to add a fuel line antifreeze or a fuel conditioner to the remaining fuel in the tank. This will help to lower the freezing point of the fuel and prevent the fuel lines from becoming brittle and cracking. For diesel-powered generators, it’s recommended to use a fuel line antifreeze specifically designed for diesel engines.
Storage Tips
In addition to draining the fuel, it’s also important to follow some basic storage tips to ensure the longevity of your generator. These include storing the generator in a dry and well-ventilated area, away from direct sunlight and moisture. You should also cover the generator with a breathable cover to protect it from dust and debris. Regularly inspect the generator and its components to ensure they are in good working condition before storing it for an extended period.
