The smell of fresh-cut grass and the satisfying hum of a lawn mower are synonymous with summer. But what happens when your trusty mower sputters and coughs, refusing to start? One of the most common culprits behind a lawn mower’s reluctance to fire up is a dirty gas tank. Old, stale gasoline can clog fuel lines, gum up the carburetor, and ultimately prevent your engine from running smoothly. This comprehensive guide will walk you through the process of cleaning your lawn mower gas tank, from preparation to putting everything back together.
A Quick Overview:
Cleaning out a lawn mower gas tank is a relatively simple task that involves removing old gasoline, cleaning the tank thoroughly, and then reassembling it. This process will help ensure that your mower receives clean fuel and starts reliably every time.
Preparing for the Clean-Out: Safety First!
Before you start tinkering with your lawn mower’s gas tank, it’s crucial to prioritize safety. Here’s how to prepare:
- Wear safety glasses: Gasoline is flammable and can cause eye irritation.
- Work in a well-ventilated area: Gasoline fumes are harmful, so ensure you have adequate airflow.
- Keep fire and heat sources away: Do not smoke or work near open flames.
- Have a fire extinguisher handy: It’s always best to be prepared in case of an emergency.
- Disconnect the spark plug wire: This prevents accidental ignition while you’re working.
Draining the Gas Tank: The First Step
Once you’ve taken the necessary safety precautions, it’s time to drain the old gasoline from your lawn mower’s tank.
Step 1: Empty the Tank
- Locate the fuel shut-off valve: This valve is usually found on the fuel line leading to the carburetor.
- Close the fuel shut-off valve: This will prevent any further fuel from entering the carburetor.
- Remove the fuel cap: Carefully unscrew and remove the gas cap.
- Find a suitable container: Use a clean, airtight container, such as a glass jar or metal can, to collect the old gasoline.
- Position the tank over the container: Carefully tilt the mower to drain the gas into the container.
- Keep the container low: This will help to prevent spills and ensure complete drainage.
Step 2: Dispose of the Old Gasoline Properly
After draining the gas tank, you’ll need to dispose of the old gasoline properly.
- Do not pour it down the drain or into the ground: Gasoline is a hazardous substance and can contaminate water sources.
- Look for local recycling facilities: Many communities have designated recycling centers that accept old gasoline.
- Contact a local auto repair shop: They may be willing to accept old gasoline for disposal.
Cleaning the Gas Tank: Time for a Deep Clean
Now that the old gasoline is out of the way, it’s time to thoroughly clean the gas tank to remove any remaining residue.
Step 1: Preparing the Tank for Cleaning
- Remove the tank from the mower: This allows you to access and clean the tank more easily.
- Remove the fuel line connections: Carefully disconnect the fuel lines from the tank.
- Inspect the tank for damage: Check for any cracks, holes, or rust.
- Rinse the tank with water: Use a hose with a nozzle attachment to rinse out any loose debris.
Step 2: Cleaning the Tank with a Cleaning Solution
- Choose a suitable cleaning solution: Common options include gasoline tank cleaner, carburetor cleaner, or even plain white vinegar.
- Pour the cleaning solution into the tank: Follow the instructions on the cleaning product for the appropriate amount.
- Securely close the gas cap: This will trap the cleaning solution inside.
- Shake or swirl the tank: This helps distribute the cleaning solution and loosen any remaining residue.
- Let the tank soak: Allow the tank to soak for the recommended time, usually around 30 minutes.
Step 3: Rinsing and Drying the Tank
- Empty the cleaning solution: Carefully pour the cleaning solution into a suitable container for disposal.
- Rinse the tank thoroughly with water: Use a hose to rinse out any remaining cleaning solution.
- Shake the tank to remove excess water: Tip the tank upside down to drain any remaining water.
- Allow the tank to dry completely: This is crucial to prevent rust and corrosion.
Reassembling the Tank: Putting It All Back Together
Once the tank is thoroughly cleaned and dried, it’s time to put everything back together.
- Reconnect the fuel lines: Ensure that the fuel lines are securely connected to the tank.
- Reinstall the tank on the mower: Make sure the tank is properly secured in place.
- Reconnect the spark plug wire: This is crucial to ensure the safety of your mower.
Preventative Measures: Keeping Your Lawn Mower Gas Tank Clean
Cleaning your lawn mower gas tank isn’t a one-time event. Here are some tips to prevent future buildup and maintain a clean fuel system:
- Use fresh gasoline: Always use fresh gasoline, ideally no older than 30 days.
- Add fuel stabilizer: This helps prevent gasoline from breaking down and forming gum or varnish.
- Empty the tank before storing the mower: This prevents stale gasoline from sitting in the tank over the winter.
Conclusion: Ensuring a Smooth Ride
Cleaning out your lawn mower gas tank is a relatively straightforward process that can dramatically improve your mower’s performance. By following these steps, you can ensure that your mower receives clean fuel, runs smoothly, and starts reliably every time. Remember to prioritize safety, dispose of old gasoline properly, and take preventative measures to keep your fuel system clean. With a little effort, you can keep your lawn mower running like a dream for years to come.
Frequently Asked Questions
1. Why should I clean my lawn mower gas tank?
Cleaning your lawn mower gas tank is essential to prevent fuel from going bad and causing engine problems. Over time, gasoline can oxidize and form gum and varnish deposits that clog fuel lines and carburetor jets, leading to poor performance, difficulty starting, and even engine damage. Regular cleaning helps maintain optimal fuel flow and ensures smooth operation.
Additionally, cleaning the tank removes moisture and contaminants that can accumulate in the gas, leading to rust and corrosion within the tank itself. This helps to prolong the lifespan of the tank and prevents potential leaks or malfunctions.
2. How often should I clean my lawn mower gas tank?
It’s a good practice to clean your lawn mower gas tank at least once a year, or more frequently if you use the mower often. If you notice any signs of fuel problems, like difficulty starting or poor performance, it’s time for a cleaning.
You can also check the fuel for any signs of sediment or discoloration. If you see any signs of degradation, it’s best to clean the tank. By keeping your tank clean, you ensure your mower runs smoothly and efficiently.
