The joy of a manicured lawn is often overshadowed by the frustration of a sputtering, coughing lawnmower. One of the most common culprits behind this unwelcome performance is a clogged gas line. This article will walk you through the process of identifying and resolving a clogged gas line, equipping you with the knowledge and skills to get your mower back in tip-top shape. We’ll cover everything from identifying the symptoms of a clogged gas line to the step-by-step cleaning procedure.
Understanding a Clogged Gas Line
A clogged gas line occurs when debris, varnish, or other contaminants build up inside the fuel lines, restricting the flow of gasoline to the carburetor. This can happen due to several reasons, including using old or stale gas, neglecting regular maintenance, or using a fuel additive that’s incompatible with your mower.
Identifying the Symptoms of a Clogged Gas Line
Before diving into the cleaning process, it’s essential to be certain that a clogged gas line is the culprit behind your lawnmower’s woes. Here are some telltale signs:
1. Difficulty Starting:
If your lawnmower struggles to start or sputters and dies soon after ignition, a clogged gas line might be the culprit.
2. Engine Stalling:
A clogged gas line can cause the engine to stall intermittently or completely, especially under load.
3. Reduced Power:
You may notice a decrease in your lawnmower’s power and performance, making mowing tasks more challenging.
4. Fuel Leak:
A clogged gas line can lead to fuel leaking from the fuel tank or lines, potentially posing a safety hazard.
Preparing to Clean Your Lawn Mower Gas Line
Before you start cleaning, ensure you have the right tools and materials:
- Safety glasses: Protect your eyes from potential splashes.
- Gloves: Protect your hands from fuel and cleaning agents.

Step-by-Step Guide to Cleaning Your Lawn Mower Gas Line
Now, let’s delve into the cleaning process:
1. Disconnect the Fuel Lines
a. Locate the Fuel Lines: Your lawnmower will have one or two fuel lines connecting the fuel tank to the carburetor.
b. Disconnect the Lines: Using a screwdriver, carefully loosen the clamps securing the fuel lines to the carburetor and fuel tank.
2. Clean the Fuel Tank and Lines
a. Drain the Fuel Tank: Carefully remove the fuel tank cap and drain the fuel into a suitable container.
b. Clean the Fuel Tank: Use a clean rag to wipe out any debris or residue from inside the tank. If necessary, you can use a cleaning solution specifically designed for fuel tanks.
c. Clean the Fuel Lines: Using fuel line cleaner, flush the fuel lines to remove any obstructions. You can use a small brush or pipe cleaner to help dislodge stubborn debris.
3. Replace the Fuel Filter
a. Locate the Fuel Filter: Your lawnmower’s fuel filter is typically located between the fuel tank and the carburetor.
b. Remove the Old Filter: Using a fuel filter wrench, carefully remove the old fuel filter.
c. Install the New Filter: Replace the old filter with a new one, ensuring it’s properly seated.
4. Reconnect the Fuel Lines
a. Attach the Fuel Lines: Reconnect the fuel lines to the carburetor and fuel tank, ensuring they are securely clamped.
b. Tighten the Clamps: Use a screwdriver to tighten the clamps, ensuring a secure connection.
Troubleshooting Tips
1. Difficult to Disconnect Fuel Lines: If you find it challenging to disconnect the fuel lines, try using a small amount of penetrating oil on the clamp to loosen it.
2. Check for Leaks: After reconnecting the fuel lines, carefully check for any leaks. Tighten the clamps further if necessary.
3. Run the Engine: Once the lines are reconnected, start the engine and allow it to run for a few minutes to ensure the fuel flow is clear.
Preventive Maintenance
Regular maintenance can prevent clogged gas lines:
- Use Fresh Fuel: Always use fresh, high-quality gasoline and avoid leaving old or stale fuel in the tank.
