Have you ever found yourself staring at a lawn mower with a fuel tank full of old, stale gasoline? Maybe you’re prepping for winter storage, getting ready to sell your mower, or just need to switch to a different fuel blend. Whatever the reason, knowing how to drain a fuel tank is a valuable skill for any lawn mower owner. In this comprehensive guide, we’ll cover the necessary steps to drain your lawn mower’s fuel tank safely and efficiently, ensuring you can tackle your next lawn mowing adventure with fresh fuel and a clear conscience.
A Quick Overview
Draining a lawn mower’s fuel tank is a simple process that involves emptying the fuel tank and cleaning the fuel system. This typically includes removing the fuel cap, siphoning out the fuel, and cleaning the fuel lines and carburetor to prevent clogs and ensure smooth operation. It’s important to note that you should always drain the fuel tank in a well-ventilated area, away from any open flames or heat sources, and wear appropriate safety gear.
Safety First: Essential Precautions
Before you start draining your lawn mower’s fuel tank, it’s crucial to prioritize safety. Fuel is highly flammable, so taking these precautions is essential:
1. Find a Safe Location:
- Ventilation: Choose a well-ventilated area, preferably outdoors, to minimize the risk of fuel fumes accumulating.
- Distance from Heat: Keep the lawn mower and fuel away from any heat sources like stoves, open flames, or even direct sunlight.
2. Protective Gear:
- Eye Protection: Wear safety glasses to protect your eyes from potential splashes or fumes.
- Gloves: Disposable gloves will protect your hands from fuel and its irritating properties.
Step-by-Step Guide to Draining Your Lawn Mower Fuel Tank
Now that you’ve taken the necessary safety precautions, let’s dive into the step-by-step process of draining your lawn mower’s fuel tank:
1. Turn Off the Mower and Remove the Fuel Cap:
- Make sure the lawn mower engine is completely shut off and cold before starting.
- Locate the fuel cap on your mower’s tank, usually secured with a spring-loaded latch or a screw-on cap.
- Carefully remove the cap to allow air into the tank as you drain the fuel.
2. Siphon Out the Fuel:
- Gather Supplies: You’ll need a siphon pump, a fuel-safe container, and a clean rag.
- Start Siphoning: Place the siphon hose into the fuel tank, ensuring it reaches the bottom.
- Prime the Siphon: Use your mouth to create suction and start the siphon flow. It might be necessary to suck on the hose a few times to get the fuel flowing.
- Alternative Method (If Necessary): If you don’t have a siphon pump, you can use a clean fuel-safe container and a small hose. Insert the hose into the fuel tank and carefully pour the fuel into the container. Be mindful of spills and take your time.
3. Clean the Fuel Lines and Carburetor (Optional)
- Cleaning Fuel Lines: If you’re experiencing fuel system problems, you may need to clean the fuel lines. Disconnect the fuel lines from the carburetor and tank. Use a fuel-safe cleaner and a small brush to remove any debris or buildup inside the lines.
- Cleaning the Carburetor: For persistent problems, cleaning the carburetor may be necessary. Consult your lawn mower’s manual or search for a specific guide for your model online for detailed instructions.
Disposing of Old Fuel Properly
Once you’ve drained the fuel tank, it’s crucial to dispose of the old gasoline responsibly. Improper disposal can be dangerous and harmful to the environment.
1. Find a Designated Fuel Collection Point:
- Check with your local waste management facility or recycling center for designated fuel collection points.
- Contact your local environmental agency or search online for authorized fuel disposal locations near you.
2. Securely Store Fuel:
- If you need to temporarily store old fuel, do so in a tightly sealed, approved fuel container.
- Label the container clearly with the fuel type and store it in a cool, dry, well-ventilated area, away from heat sources and direct sunlight.
3. Avoid Pouring Fuel Down the Drain:
- Never pour old fuel down the drain or into the ground. This can contaminate water sources and harm wildlife.
Maintaining a Clean Fuel System
- Use Fresh Fuel: Always use fresh gasoline in your lawn mower, ideally within 30 days of purchase.
- Fuel Stabilizer: Consider adding a fuel stabilizer to your gasoline, especially when you’re storing your mower for extended periods.
- Regular Maintenance: Regularly inspect your fuel system for any signs of leaks, clogs, or wear and tear.
Tips for Success
- Check your mower’s manual: Before draining your fuel tank, refer to your lawn mower’s manual for specific instructions and warnings regarding fuel system maintenance.
- Wear appropriate attire: Always wear appropriate clothing, safety glasses, and gloves when handling fuel.
- Be patient: The draining process might take some time, especially if you have a large fuel tank.
- Work in a safe environment: Ensure the area is well-ventilated and away from any heat sources.

FAQs
Why Do I Need to Drain My Lawn Mower’s Fuel Tank?
Draining your lawn mower’s fuel tank is important for several reasons. Firstly, it prevents the fuel from going bad. Over time, gasoline can deteriorate and form varnish and gum, clogging fuel lines and carburetor jets. This can lead to engine problems and difficult starting. Secondly, it reduces the risk of fire hazards. Fuel spills and leaks can be dangerous, especially when working with hot engines. Draining the fuel tank before storing your mower helps eliminate these risks.
How Often Should I Drain My Lawn Mower’s Fuel Tank?
It’s recommended to drain your lawn mower’s fuel tank at least once a year, especially before long-term storage during the off-season. You should also consider draining the tank if you haven’t used the mower for several months or if the fuel seems old or discolored. However, if you’re using your mower frequently, it’s generally okay to leave the fuel in the tank for short periods. Just make sure it’s fresh and doesn’t contain any water or debris.
What Supplies Do I Need to Drain a Lawn Mower Fuel Tank?
You’ll need a few basic supplies to drain your lawn mower’s fuel tank safely and effectively. Firstly, you’ll need a fuel container, preferably a gas can with a tight-fitting lid.

Lastly, you’ll need some absorbent materials like rags or paper towels to clean up any spills.
How Do I Safely Drain My Lawn Mower’s Fuel Tank?
Before you start, it’s crucial to work in a well-ventilated area and ensure the engine is completely cool. Disconnect the spark plug wire to prevent accidental starting. Next, carefully remove the fuel cap and use the siphon pump or transfer pump to extract the fuel from the tank into the fuel container. Be careful not to spill any fuel, and if any spills occur, clean them up immediately with absorbent materials. Once the tank is empty, you can reconnect the spark plug wire.
What Should I Do with the Drained Fuel?
The drained fuel should not be poured down the drain or into the ground, as it can contaminate the environment. Instead, dispose of it responsibly. You can take it to a local gas station or automotive repair shop that accepts fuel for disposal. Some local recycling centers also accept fuel for proper disposal. Alternatively, you can mix the drained fuel with a small amount of fresh gasoline to dilute it and use it in a small engine like a weed trimmer.
