Husqvarna Push Mower Fuel Filter: Step-By-Step Replacement Guide

If your Husqvarna push mower is hard to start, leaking gas, running rough, or won't start at all, you may need to replace the fuel filter. This is a relatively simple task, but it's important to make sure you have the correct parts for your specific mower model. You can find the model number on the mower itself, and then order the corresponding fuel filter online or from an authorized Husqvarna dealer. Once you have the new fuel filter, you can refer to one of the many online guides or videos to walk you through the replacement process step-by-step.

Where to find the model number

To locate the model number of your Husqvarna push mower, you can refer to the product itself or the operator's manual. The model number is usually found on a rating plate or product plate attached to the mower. This plate could be a small metal or plastic plate, a label, or a sticker. The appearance and location of the rating plate may vary depending on the type of product, model, and year of manufacture.

For example, if you own a Husqvarna robotic lawn mower, the rating plate can typically be found under the display hatch or, for models without a display hatch, underneath the mower on the chassis or at the back of the chassis under the cover.

If you own a ride-on front mower or rider, the rating plate is usually located inside the chassis under the seat. For lawnmowers, the plate is typically at the rear of the cutting deck. Garden tractors usually have the rating plate located under the seat, while zero-turn mowers will have it on the left side of the chassis, near the engine.

Additionally, you can refer to the Husqvarna Connect app or Automower Connect app if you have added your product to it. These apps provide access to product data, including the model number and serial number.

Signs of a clogged fuel filter

A clogged fuel filter can cause a lot of issues with your Husqvarna push mower. Here are some signs that your fuel filter is clogged:

Changes in the Engine's Sound

The engine may start to sputter instead of making a purring sound. This is because the combustion chamber isn't getting enough fuel due to the clogged filter restricting the gas flow.

Inconsistent Engine Performance

A clogged fuel filter can cause the engine to surge or sputter, especially when accelerating or climbing steep inclines. You may not be able to drive as fast as you used to.

Engine Stalling

Engine stalling, especially while accelerating, can be a sign of a clogged fuel filter. Depending on the severity of the clog, the engine may stall rapidly or refuse to start at all.

Engine Misfire and Rough Idling

A clogged fuel filter can cause the engine to misfire and deliver poor mileage and rough idling.

Difficulty Starting the Engine

A clogged fuel filter can trap dirt, debris, and other impurities, preventing the required amount of gas from reaching the engine for the combustion process.

Increased Fuel Consumption

A clogged fuel filter can cause the engine to work harder, resulting in higher fuel usage.

Emission of Black Smoke

A clogged fuel filter can disrupt the air-gas ratio, leading to black smoke being emitted from the exhaust.

Dirty Spark Plug

If the spark plug is dirty, it could be an indication that the fuel filter is clogged, causing excess gas to end up on the spark plug and leading to engine problems.

How to know if the filter is faulty

A fuel filter is responsible for removing contaminants from the gas before they can reach the fuel injection system and engine. Over time, fuel filters collect dirt and debris, which can hinder engine performance and allow harmful particles into sensitive areas, leading to potential damage and costly repairs.

• Poor fuel economy and acceleration: If your vehicle's fuel mileage per gallon starts to dip, it could be due to a dirty or clogged fuel filter. This can also result in poor acceleration as the fuel struggles to reach the engine, decreasing fuel efficiency.
• Trouble starting: If your car is having trouble starting or won't start at all, a clogged fuel filter could be preventing enough fuel from reaching the engine.
• Vehicle stalling: Repeated stalling of your vehicle could be due to a clogged fuel filter, which can prevent sufficient fuel from reaching the engine even after it has been started.
• Misfiring or rough idling: A clogged fuel filter can cause low fuel pressure in your system, leading to misfiring or rough idling as your vehicle struggles to stay running at idle speed.
• Strong gas odour: A clogged fuel filter can cause unburnt fuel to escape through the exhaust system, resulting in a strong gas odour in the cabin of your car.
• Unusual engine noise: As the fuel pump works harder to push gas through a clogged filter, it may produce a strange noise that can be heard inside the vehicle.
• Check engine light comes on: Low fuel pressure caused by a clogged fuel filter may trigger the check engine light to come on.

Step-by-step guide to replacing the filter

Step-by-step Guide to Replacing the Fuel Filter on a Husqvarna Push Mower

Step 1: Locate the Fuel Filter

Before starting, make sure you have the correct replacement fuel filter for your Husqvarna push mower model. The fuel filter is usually located along the fuel line, which runs from the gas tank to the carburettor.

Step 2: Disconnect the Fuel Line

Using a pair of pliers, carefully disconnect the fuel line from the carburettor by gently pulling on the fuel line connector. This will release the fuel line, giving you access to the fuel filter.

Step 3: Remove the Old Fuel Filter

With the fuel line disconnected, you can now remove the old fuel filter. Gently pull it out of the fuel line, taking care not to damage the fuel line or any nearby components.

Step 4: Install the New Fuel Filter

Take the new fuel filter and insert it into the fuel line securely. Ensure that it is firmly seated and aligned correctly.

Step 5: Reconnect the Fuel Line

Using the pliers again, reconnect the fuel line to the carburettor by pushing the fuel line connector firmly into place.

Step 6: Check for Leaks

Once the new fuel filter is installed and the fuel line is reconnected, check for any signs of fuel leaks around the connection points and the new fuel filter. If there are no leaks, start the mower and let it run for a few minutes to ensure proper fuel flow and engine performance.

Step 7: Dispose of the Old Fuel Filter Properly

Finally, don't forget to dispose of the old fuel filter responsibly, following any local guidelines for hazardous waste disposal.

By following these steps, you can replace the fuel filter on your Husqvarna push mower, ensuring optimal fuel flow and engine performance. Remember to consult your owner's manual or seek assistance from a qualified technician if you have any questions or concerns during the process.
