Replacing The Fuel Pump On Your Husqvarna: Step-By-Step Guide

A fuel pump is an essential component of any engine, and knowing how to change one is a valuable skill for anyone who owns a Husqvarna machine. Whether it's a lawnmower, a chainsaw, or a motorcycle, keeping your fuel pump in good condition is key to the longevity of your equipment. In this guide, we'll take you through the steps to change a fuel pump on a Husqvarna, outline the tools and parts you'll need, and offer some helpful tips to make the process as smooth as possible.

Empty the fuel tank

To empty the fuel tank of your Husqvarna machine, follow these steps:

Firstly, locate the fuel tank. This will vary depending on the type of Husqvarna machine you own. For example, if you have a ride-on mower, you will need to open the engine cover to access the fuel filter and tank. Once you have located the fuel tank, the next step is to prepare the area. Place a container or cloth underneath the tank to catch any spilled fuel. Be very cautious as fuel is highly flammable and the fumes are explosive, so it is important to ensure adequate ventilation and avoid any sources of ignition, such as smoking, during this process.

Next, you will need to remove the fuel from the tank. This can be done in several ways, depending on the type of Husqvarna machine and the tools you have available. One method is to use a siphon pump to remove the fuel. Attach the siphon pump to the fuel tank and pump the fuel into a separate container. Another method is to use a drain plug, if your Husqvarna machine is equipped with one. Simply open the drain plug and allow the fuel to drain into a suitable container. If your Husqvarna machine does not have a drain plug, you may need to carefully tilt or turn the machine to empty the fuel tank. Ensure that you do this over a container that can catch the fuel and be very careful not to spill any fuel.

Once the fuel tank is empty, it is important to clean the area, ensuring that any spilled fuel is wiped up and disposed of properly. Finally, before continuing with any maintenance or repairs, such as changing the fuel pump or filter, allow the area and any parts to air dry completely to minimise the risk of ignition.

Remove the fuel hose

To remove the fuel hose on a Husqvarna chainsaw, follow these steps:

Firstly, it is important to note that you should always exercise caution when performing any maintenance on your Husqvarna chainsaw. Ensure that you have emptied the fuel tank before beginning and refrain from smoking during the process.

Now, to begin removing the fuel hose:

• Compress the fuel hose gently to prevent any fuel leakage while you work.
• Using a pair of flat pliers, carefully move the hose clips away from the fuel filter. Be cautious, as a small amount of fuel may leak during this step.
• With the hose clips moved, you can now pull the fuel hose away from the tank unit and out from the filter.

At this stage, you will have successfully removed the fuel hose, and you can proceed to replace the fuel filter or perform any other necessary maintenance. Remember to exercise caution and always follow the safety guidelines provided by the manufacturer when working with fuel and machinery.

Fit the new fuel pump

To fit the new fuel pump, follow these steps:

Firstly, ensure that the arrow on the new fuel pump is pointing in the correct direction. The arrow should be pointing towards the engine. This is crucial, as installing the fuel pump in the wrong direction can cause serious issues. With the arrow pointing in the right direction, push the new fuel pump into the ends of the hoses. You may need to apply liquid detergent or a soap solution to the ends of the fuel pump to make the connection easier.

Next, move the hose clips back towards the fuel pump and secure them in place. Ensure that the hose clips are tight enough to prevent any leaks. Once the new fuel pump is securely installed, you can close up your Husqvarna machine and start it up to test the new fuel pump.

It is important to note that you should always refer to your product's operator's manual for specific instructions and safety precautions before attempting any repairs or replacements. Additionally, always exercise caution when working with fuel and ensure the area is well-ventilated to prevent the buildup of flammable fumes.

Refit the fuel hose

To refit the fuel hose, ensure you have a new fuel filter. Refer to your product's operator's manual for the correct fuel filter type.

Before starting this procedure, make sure to empty the fuel tank. Do not smoke while performing this task.

Now, pull out the fuel hose from the tank unit. Fit the new fuel filter and ensure that the arrow is pointing towards the engine. Then, you can refit the fuel hose with the filter in the tank unit.

If necessary, a soap solution or liquid detergent can be applied to the ends of the fuel filter to ease mounting.

Check the fuel filter

To check the fuel filter on your Husqvarna lawn mower, you will need to check the fuel system at the beginning of each season.

First, check the fuel tank cap and the seal for the fuel tank cap to make sure that they are not damaged. Next, check the fuel hose to make sure that there are no leaks. If the fuel hose is damaged, do not attempt to fix it yourself. Contact your local authorised dealer.

If you notice fuel leaking from your walk-behind mower, turn off the product immediately and contact your local authorised dealer. Check the engine for leaks regularly. Be careful with the fuel, as it is flammable and the fumes are explosive. This can cause injuries or even death.
