Expert Advice: How to Drain Gas from Generac Generator Like a Pro

Knowing how to drain gas from your Generac generator is an essential skill for any homeowner who relies on this backup power source. Whether you’re preparing your generator for storage during the off-season, dealing with old or contaminated fuel, or simply need to make space for fresh gas, this guide will walk you through the process safely and efficiently.

Why Drain Gas From Your Generac Generator?

There are several reasons why you might need to drain the gas from your Generac generator:

• Storage: Gasoline degrades over time, becoming less volatile and prone to gumming up the carburetor and fuel lines. Draining the gas before storing your generator for extended periods helps prevent these issues.
• Fuel Contamination: If you suspect your fuel has become contaminated (e.g., water ingress, ethanol separation), draining and replacing it is crucial to avoid engine damage.
• Maintenance: Some maintenance tasks, such as cleaning the carburetor, may require draining the fuel tank.
• Safety: If you need to transport your generator or perform repairs, it’s generally safer to drain the fuel tank to minimize the risk of spills or leaks.

Safety First: Essential Precautions

Before you start draining gas from your Generac generator, always prioritize safety:

• Wear Safety Gear: Protect yourself from spills and fumes by wearing safety glasses, gloves, and long pants.
• Work in a Well-Ventilated Area: Gasoline fumes are flammable and dangerous. Ensure you’re working in a well-ventilated area and keep any ignition sources away.
• Ground the Generator: To prevent static electricity buildup, ground the generator frame using a grounding wire.
• Use Appropriate Containers: Use a clean, sealed container specifically designed for gasoline storage. Never use containers that previously held other substances.
• Dispose of Fuel Properly: Dispose of the drained gasoline responsibly. Check with your local regulations for proper disposal methods.

Step-by-Step Guide to Draining Gas From Your Generac Generator

1. Turn Off the Generator: Ensure the generator is completely shut off and disconnected from any power sources.
2. Cool Down the Engine: Allow the engine to cool down completely before proceeding. This prevents hot fuel from being spilled and reduces the risk of burns.
3. Locate the Fuel Drain Valve: Most Generac generators have a fuel drain valve located on the bottom of the fuel tank. Refer to your owner’s manual for the exact location and instructions for your specific model.
4. Prepare Your Container: Place your clean gasoline container beneath the fuel drain valve.
5. Open the Drain Valve: Carefully open the fuel drain valve, allowing the gas to flow into the container.
6. Monitor the Flow: Keep an eye on the flow and stop draining once the fuel tank is empty.
7. Close the Drain Valve: Once you’ve drained the fuel, close the drain valve tightly.
8. Dispose of Fuel Properly: Dispose of the drained fuel responsibly according to local regulations.

Tips for Draining Gas Effectively

• Use a Funnel: For easier and less messy draining, use a funnel to direct the fuel into your container.
• Clean the Drain Valve: If you notice any debris or buildup around the drain valve, clean it before and after draining.
• Add Fuel Stabilizer: If you’re storing your generator for an extended period, add fuel stabilizer to the fresh gas you fill the tank with. This helps prevent fuel degradation.

Maintaining Your Generac Generator for Optimal Performance

Draining the gas is just one part of maintaining your Generac generator. Here are some other essential maintenance tasks:

• Regular Oil Changes: Check your owner’s manual for recommended oil change intervals.
• Air Filter Replacement: Replace the air filter regularly to ensure proper airflow and engine performance.
• Spark Plug Inspection: Inspect the spark plugs for wear and tear and replace them as needed.
• Battery Maintenance: Keep the generator’s battery charged and in good condition.

Keeping Your Generator Ready for When You Need It Most

By following these tips and performing regular maintenance, you can ensure your Generac generator remains in peak condition, ready to provide reliable backup power when you need it most.

Answers to Your Most Common Questions

Q: How often should I drain the gas from my Generac generator?
A: It’s recommended to drain the gas every 3-6 months if you’re storing your generator for extended periods. If you use your generator frequently, draining the gas less often might be sufficient.
Q: Can I use the drained gas in my car?
A: It’s generally not recommended to use drained gas in your car. The fuel may have degraded and could potentially harm your vehicle’s engine.
Q: What if my generator doesn‘t have a fuel drain valve?
A: If your generator lacks a fuel drain valve, you can try siphoning the fuel using a siphon pump. Be extremely careful not to create sparks during the process.
Q: What are some signs that my fuel has gone bad?
A: Signs of bad fuel include a strong gasoline odor, a change in fuel color, or difficulty starting the generator.
Q: What happens if I don’t drain the gas from my generator?
A: Leaving old gas in the tank can lead to gumming up the carburetor and fuel lines, causing engine problems and potentially requiring costly repairs.
