Replacing Snowblower Fuel Lines: A Step-By-Step Guide

Replacing a snowblower fuel line is a straightforward process that can be completed in a few hours. The fuel line is responsible for carrying fuel from the gas tank to the engine, and if it is cracked or damaged, the engine will not start. This guide will cover the steps to replace the fuel line on Craftsman, MTD, Murray, Troybilt, Husqvarna, Toro, Murray, Ariens, and Noma snowblowers. Before beginning, ensure you have the necessary tools, including a Phillips screwdriver and a socket and ratchet set.

Drain the fuel tank and disconnect the spark plug wire

To replace a snowblower fuel line, one of the first steps you should take is to drain the fuel tank and disconnect the spark plug wire. This is a simple but necessary project that requires very few supplies and tools, but it is important for the maintenance of your snowblower.

First, locate a safe outdoor space to work in. You should be away from heating units and open flames, and on a flat surface to avoid slipping. You will also need to allow the engine to cool down before touching it. Wear safety gloves, and make sure the snowblower is switched off.

Next, you will need to drain the fuel tank. You can do this by using a siphon pump. Place one end of the tube into the fuel tank and the other end into a catch pan. Squeeze the pump to start draining the fuel. Once you have removed most of the gas, replace the fuel tank cap and start the engine. Let it run until it shuts off due to a lack of gas.

Now you can disconnect the spark plug wire. The spark plug should be located on the top of the unit or under a cover. Carefully remove the spark plug wire from the spark plug.

By draining the fuel tank and disconnecting the spark plug wire, you can safely proceed with replacing the fuel line in your snowblower.

Remove the electric starter switch

To remove the electric starter switch, you will need a screwdriver and a socket wrench set with a ratchet. Before beginning any work on your snowblower, ensure that the engine is not locked up. You can check this by pulling the recoil starter rope to ensure the engine spins normally.

First, disconnect the spark plug wire by pulling it straight up and off the plug. Next, remove the two screws that secure the switch box to the engine. Pull the switch box away from the engine and let it hang by the power cord going to the starter motor.

Now, you can remove the electric starter switch. Remove the two starter motor mounting screws and pull the starter motor off the engine. The starter switch should now be exposed. Remove the mounting screws and pull the starter switch off the bracket, letting it hang by the electrical cord.

At this point, the electric starter switch has been successfully removed. You can now install a new one, following the above steps in reverse.

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. You can then remove the muffler shroud mounting screws. Work the engine shroud off the carburetor mounting studs, ensuring that the primer hose and breather hose remain connected.

It is important to note that you can remove the engine shroud without removing the muffler shroud, but the muffler shroud must be removed for reassembly. This is because the engine shroud fits under the bottom lip of the muffler shroud.

If you are having trouble removing the fuel line, it may be pressed into a groove and stuck. In this case, you may need to further disassemble the front cover, starter, and possibly part of the controls. However, removing the engine shroud first will make it easier to access the fuel line.

Once you have removed the engine shroud, you can then release the fuel line clamp and pull the fuel line off the fuel filter. Repeat this process to release the other end of the fuel line from the carburetor and remove it completely.

Remove the fuel line

Removing the fuel line from your snowblower is a delicate process, but with the right tools and steps, it can be done efficiently. Here is a detailed guide to help you through the process:

First, ensure your safety by positioning the snowblower in a well-ventilated area. Next, drain any remaining fuel from the tank to avoid spills or accidents. Once the tank is empty, locate the spark plug wire and carefully pull it up and away from the plug. This will prevent any accidental ignition during the process.

Now, let's move on to the fuel line itself. Start by releasing the fuel line clamp that holds the fuel line in place. You can do this by simply squeezing the clamp with your fingers or using a pair of pliers if needed. With the clamp released, gently pull the fuel line away from the fuel filter. It may require some wiggling and gentle force to remove it completely. Repeat this process on the other end of the fuel line, where it connects to the carburetor. Again, gently pull the fuel line off the carburetor, being careful not to damage any nearby components.

If your snowblower model requires further disassembly for access, make sure to take note of all the steps for reassembly. Some models may require removing the engine shroud and other components for easier access to the fuel line. Always refer to your snowblower's manual or seek guidance from a professional if you're unsure about any steps.

Once the fuel line is completely free from both ends, set it aside, and you can now prepare to install the new fuel line. Remember to dispose of the old fuel line properly and safely.

Install the new fuel line

To install the new fuel line, begin by connecting the new fuel line to the tank. Secure it in place with a fuel line clamp. Next, repeat this process to connect the other end of the new fuel line to the carburetor. Ensure that the breather hose is passed through the opening and lines up with the rocker cover breather hose fitting. Once the new fuel line is connected to both the tank and the carburetor, you can move on to reinstalling the engine shroud.

Before reinstalling the engine shroud, remove the muffler shroud. To do this, first pull off the muffler shroud mounting bolts. Then, release the wire control cables from the retainer clip and pull off the muffler shroud. Now you can proceed with reinstalling the engine shroud. Align the choke knob shaft and the 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 correctly.

Secure the breather hose with a clamp and reinstall the acorn nuts to secure the engine shroud to the engine. Slide the wire control cables back into the retainer clip and position the muffler shroud on the engine. Reinstall the mounting bolts for the muffler shroud.

At this point, you can continue with the remaining steps to complete the replacement of the snowblower fuel line.
