Replacing Fuel Line On Toro Snowblower: A Step-By-Step Guide

If your Toro snowblower is leaking gas, you may need to replace the fuel line. The fuel line carries fuel from the gas tank to the engine, and if it's cracked or damaged, the engine won't start. This is a complex process that requires various tools, including a wrench, pliers, a screwdriver, and a socket wrench. You'll also need to drain the fuel tank and disconnect the spark plug wire.

Drain the fuel tank and disconnect the spark plug wire

Before you begin to work on your Toro snowblower, it is important to prioritise safety. Snowblowers are powerful machines and can be dangerous if you forget about safety when you're around them. Always shut off the machine and give it time to cool down before you begin any maintenance work. Even then, wear work gloves to protect your hands. Inserting earplugs before you start up a snowblower is also recommended, as the engine is loud, and the noise could damage your hearing over time. Wear eye protection and avoid wearing any loose-fitting clothing that could become entangled in the moving parts of the machine.

Now, to drain the fuel tank and disconnect the spark plug wire:

• Position the snowblower in a well-ventilated area, preferably outdoors, away from heating units, open flame, and enclosed spaces (to avoid carbon monoxide poisoning).
• Make sure the snowblower is turned off and the engine is cool to prevent any accidental injuries.
• Pull the spark plug wire up and off the plug. Gently pull the boot off to ensure there is no electrical charge.
• To drain the fuel from the tank, you can use a siphon pump. Remove the fuel tank cap and place one end of the siphon pump's tube into the fuel tank, placing it as deep as possible. Place the other end of the tube into a catch pan.
• Squeeze the pump on the siphon pump to drain the fuel into the catch pan.
• Despite your efforts, some fuel may remain in the tank. To drain this residual fuel, replace the fuel tank cap, start the engine, and let it run until it shuts off on its own due to a lack of gas.
• Alternatively, you can run the snowblower until the tank is empty.

Once you have drained the fuel tank and disconnected the spark plug wire, you can proceed with the next steps to replace the fuel line on your Toro snowblower.

Remove the engine shroud

To remove the engine shroud, you will need to first pull off the choke and throttle knobs. Next, remove the acorn nuts that secure the carburetor to the engine. Then, remove the muffler shroud mounting screws. Finally, work the engine shroud off the carburetor mounting studs, leaving the primer hose and breather hose connected.

Step 1: Pull off the choke and throttle knobs.

Locate the choke and throttle knobs on your Toro snowblower. These knobs are usually found on the engine shroud, near the carburetor. Grip the knobs firmly and pull them off.

Step 2: Remove the acorn nuts.

The acorn nuts secure the carburetor to the engine. Using the appropriate tool, remove these nuts to detach the carburetor from the engine. Place the nuts in a safe place so you can access them easily when reassembling the engine.

Step 3: Remove the muffler shroud mounting screws.

The muffler shroud is attached to the engine with mounting screws. Remove these screws using the correct screwdriver or tool. Again, keep the screws in a safe place for reassembly.

Step 4: Work the engine shroud off the carburetor mounting studs.

Now, you can start to remove the engine shroud. Gently work it off the carburetor mounting studs, taking care not to damage any connected hoses or components. Make sure to leave the primer hose and breather hose connected as you remove the engine shroud.

By following these steps, you will be able to successfully remove the engine shroud on your Toro snowblower, allowing you to access the engine and perform further repairs or replacements. Remember to keep track of all the parts you remove and their locations for easier reassembly.

Remove the fuel line

To remove the fuel line from your Toro snowblower, you will need a few tools, including a flat-head screwdriver, a wrench, and a pair of pliers. You may also need a container to catch any fuel that may leak or spill during the process.

First, locate the fuel line and the fuel filter. These are usually found underneath the snowblower's front housing. Before you do anything else, clamp off the incoming fuel line to the fuel filter to prevent fuel from leaking out.

Next, use your pliers to slide the small clamps on the fuel line aside. Then, use your flat-head screwdriver to push the fuel line off of the filter. Be careful not to break the line by simply pulling on it. Once the fuel line is released, some fuel may still drain out of the filter, so be prepared to catch it with your container.

Now, repeat the process to release the other end of the fuel line from the carburetor and remove it completely.

It is important to note that there may be some variation in the specific steps and tools required to remove the fuel line, depending on the model of your Toro snowblower. Always refer to the owner's manual or a trusted repair guide for the most accurate and safe instructions.

Install the new fuel line

To install the new fuel line, first, connect the new fuel line to the tank and secure it with the fuel line clamp. Then, connect the other end of the new fuel line to the carburetor and secure it with another clamp.

This process is the same for a range of snowblower brands, including Craftsman, MTD, Murray, Troybilt, Husqvarna, Toro, Murray, Ariens and Noma.

When replacing the fuel line, it is important to ensure that you are using the correct type of fuel line. There are three different types of 1/4" ID neoprene hose, and using the wrong type can cause the fuel line to become jammed. The correct type of fuel line for small engines is 1/4" ID, 1/2" OD.

Reinstall the engine shroud

To reinstall the engine shroud, follow these steps:

First, align the choke knob shaft and the two carburetor mounting posts with the openings on the engine shroud. Work the engine shroud onto the engine, ensuring that the breather hose passes through the opening and lines up with the rocker cover breather hose fitting.

Next, slide the breather hose over the rocker cover fitting and secure it with the clamp. Reinstall the two acorn nuts to secure the engine shroud to the engine.

Now, slide the wire control cables into the retainer clip and position the muffler shroud on the engine. Reinstall the muffler shroud mounting bolts.

Push the control rod back into the 4-way control rod receiver and line up the support bracket with the mounting holes. Reinstall the bolts in the red chute support bracket.

Finally, reinstall the belt cover using the mounting bolts. Reinstall the choke and throttle knobs.
