Fuel Line/Filter - Maintenance & Replacement

The fuel line, in particular, plays a vital role in delivering fuel to the engine. Fuel lines can deteriorate or become clogged, severely affecting the mower's overall power.


Signs of a Damaged Fuel Line
Before diving into the replacement process, it's essential to identify signs of a damaged fuel line.
Look out for the following indications:

Leaks: Notice any fuel leaks around the fuel line area.
Cracks or Wear: Examine the fuel line for cracks, wear, or visible damage.
Stalling or Poor Performance: If your lawn mower frequently stalls or experiences a loss of power, a faulty fuel line could be the culprit.
Fuel Odor: Detect a strong smell of gasoline while operating the lawn mower.

Fuel Line Replacement
Follow these steps to replace the fuel line on your lawn mower!

Gather the necessary tools
Before starting, gather a new fuel line, fuel line clamps, pliers, a fuel line removal tool, and safety gloves.

Ensure your lawn mower is turned off and the spark plug is disconnected to prevent accidental starts. Place the mower on a flat, stable surface.

Locate the fuel line
Identify the fuel line by following it from the fuel tank to the engine. Note its position and any connections it may have.

Drain the fuel
To prevent spills, empty the fuel tank by either siphoning the fuel or using a hand pump.

Remove the old fuel line
Use pliers and a fuel line removal tool, if necessary, to disconnect the old fuel line from the fuel tank and carburetor.

Install the new fuel line
Cut the new fuel line to the appropriate length, ensuring it matches the dimensions of the old one. Connect the fuel line to the fuel tank and carburetor, securing it with fuel line clamps.

Test for leaks 
Once the new fuel line is installed, reconnect the spark plug and add a small amount of fuel to the tank. Check for any leaks by inspecting the connections closely.



Fuel System Maintenance Tips!
To ensure the longevity of your lawn mower's fuel system, consider the following maintenance tips

Use clean fuel - Always use fresh, clean fuel that is specifically recommended for your lawn mower. Stale or contaminated fuel can clog the fuel line and cause performance issues.

Regular inspections - Periodically inspect the fuel line for cracks, wear, or signs of damage. Replace any damaged sections promptly.

Clean the fuel filter - Some lawnmowers have a fuel filter in the fuel line. Clean or replace it regularly to prevent debris from entering the fuel system.

Fuel tank cleanliness - Keep the fuel tank clean by regularly removing debris and sediment that may accumulate over time. Avoid storing the mower with old fuel for extended periods.

Winter storage - If you plan to store your lawn mower for the winter, empty the fuel tank and run the engine until it is out of fuel. This prevents fuel from gumming up the fuel system during the dormant period.


Taking care of your lawn mower's fuel line is essential for maintaining optimal performance. By understanding the signs of a damaged fuel line, replacing it when necessary, and following proper maintenance practices, you can ensure your lawn mower operates efficiently and reliably, giving you a well-manicured lawn for years to come!
