Knowing when to drain the gas from your gas generator is just as important as knowing how. Here are some key scenarios when you should consider draining the gas:
Before Storage: If you plan to store your gas generator for an extended period, such as during the off-season, it’s crucial to drain the gas. Leaving fuel in the tank can lead to several issues:
Fuel Degradation: Over time, gasoline can degrade and lose its volatility. This old fuel can damage the carburetor and other engine parts, making it difficult to start the generator when you need it.
Fuel System Clogs: Degraded fuel can leave behind gummy residues that clog the fuel lines, filters, and carburetor, hindering fuel flow and preventing the generator from starting.
Phase Separation: In ethanol-blended fuels, phase separation can occur when the fuel sits for too long. This separation can cause corrosion and damage to the fuel system.
Fire Hazard: Stale fuel is more prone to combustion, posing a fire hazard, especially in hot conditions.
After Prolonged Use: If you’ve been running your gas generator continuously for an extended period, it’s a good practice to drain the gas and refill it with fresh fuel. This helps to prevent the buildup of contaminants and ensures optimal engine performance.
Before Maintenance or Repairs: If you’re planning to perform any maintenance or repairs on your gas generator, it’s advisable to drain the gas to minimize the risk of fuel spills, fires, or damage to the engine.
When Using Unleaded Fuel: If your gas generator is designed to run on leaded fuel and you switch to unleaded, you should drain the fuel tank and fuel lines before refilling with unleaded gas. This prevents contamination and ensures the engine runs smoothly.
When Switching Fuel Types: If you need to switch your gas generator from gasoline to propane or vice versa, you should drain the existing fuel to avoid mixing different fuel types, which can cause engine problems.
Draining the gas from your gas generator is a relatively straightforward process, but it’s essential to follow the steps carefully to ensure safety and prevent damage to the equipment. Here’s a step-by-step guide:
Prepare the Area:
Gas Can: A suitable container for collecting the drained gas.
Funnel: To prevent spills when transferring the gas.
Rags or Absorbent Pads: To clean up any spills.
Wrench (if required): Some gas generator models may require a wrench to remove the drain plug.
Location: Choose a well-ventilated area, preferably outdoors, away from any ignition sources or open flames.
Safety Gear: Wear safety glasses and gloves to protect yourself from fuel spills and fumes.
Materials: Gather the necessary materials:
Turn Off the Gas Generator and Let it Cool:
Power Off: Ensure the gas generator is turned off and the fuel valve (if applicable) is in the “Off” position.
Cool Down: Let the gas generator cool down completely before attempting to drain the gas. This prevents the risk of burns and reduces the volatility of the fuel.
Locate the Drain Plug or Drain Valve:
Consult the Manual: Refer to your gas generator’s owner’s manual to locate the drain plug or drain valve. It’s usually located at the bottom of the fuel tank.
Types of Drains: Some gas generator models have a simple screw-type drain plug, while others may have a more sophisticated drain valve.
Drain the Gas:
Place the gas can beneath the drain valve.
Open the valve by turning it counterclockwise.
Allow the gas to drain completely into the gas can.
Once drained, close the valve by turning it clockwise.
Place the gas can beneath the drain plug.
Use the wrench (if necessary) to loosen and remove the drain plug.
Allow the gas to drain completely into the gas can.
Once drained, replace the drain plug and tighten it securely.
Drain Plug: If your gas generator has a drain plug:
Drain Valve: If your gas generator has a drain valve:
Siphoning (if no drain): If your gas generator doesn’t have a drain plug or valve, you can use a siphon pump to remove the gas. Be extremely careful when siphoning to avoid ingesting fuel.
Dispose of the Old Gas Properly:
Local Regulations: Check your local regulations for the proper disposal of old gasoline.
Hazardous Waste: Never pour old gas down the drain or on the ground, as it’s harmful to the environment.
Recycling Centers: Contact your local hazardous waste recycling center for information on how to dispose of old gas properly.
Clean Up Spills:
Immediate Action: If any gas spills during the process, clean it up immediately with rags or absorbent pads.
Ventilation: Ensure the area is well-ventilated to disperse any fuel fumes.
Refill with Fresh Gas (if needed):
Use a Funnel: When refilling the gas generator with fresh gas, use a funnel to avoid spills.
Correct Fuel: Ensure you’re using the correct type of fuel specified for your gas generator model.
Stabilizer (optional): If you plan to store the gas generator for a while, consider adding a fuel stabilizer to the fresh gas to prolong its shelf life.
Run the Gas Generator Briefly:
Check for Leaks: After refilling, run the gas generator for a few minutes to ensure there are no leaks in the fuel system.
Monitor Performance: Observe the gas generator’s performance to ensure it’s running smoothly.
Knowing when and how to drain the gas from your gas generator is a fundamental aspect of its maintenance.
