Replacing Fuel Line Connector On Tecumseh Engine: 8 To 10 Steps

Changing the fuel line connector on a Tecumseh engine can be a challenging task, especially if it is stuck or pressed into a groove. While some people suggest removing the front cover, starter, and flywheel for easier access, others claim it is possible to replace the hose without disassembling these components. One crucial tip is to use the correct fuel line size, as automotive store hoses may be too large for the application. Pushing the hose from the carburetor side and using a wire or threaded rod as a guide can make the process smoother. Additionally, using a screwdriver to lift the plate under the flywheel can reduce friction against the hose.

Using a wire to guide the new hose through

When replacing the fuel line on a Tecumseh engine, you will need to remove the gas tank. Once the hose has been disconnected at the carburetor and tank, it is important to run a thick wire through the hose to remember the passageway. This will be used to guide the new hose through.

Push the wire through the old hose, starting from the carburetor side, and then use it to guide the new hose through, pushing from the carburetor side to the gas tank side. This is easier as you will have more space to grab the hose from the gas tank side and pull.

There is a plate under the flywheel that you will need to push up using a screwdriver, as there will be too much friction against the hose. Once the hose is through this tight space, grab it with a longer-than-average pair of needle-nose pliers. The longer and thinner the pliers are, the better, as there is not much room to work with.

Grab the hose and pull it through, cutting the old hose at the carburetor end last. You will need to wiggle and move the new hose around to get it through, and you will need to lift the plate under the flywheel.

Using a 1/4 threaded rod to guide the new hose through

To change the fuel line connector on a Tecumseh engine, you'll need to buy a 1/4" ID and 7/16" OD hose. The hose found in automotive stores will be too thick to fit through the narrow passageway from the gas tank to the carburettor.

When you have the correct hose, you can use a 1/4" threaded rod to guide the new hose through. First, disconnect the old hose at the carburettor and the tank. Next, push a thick wire through the hose to remember the passageway. Then, push the hose in, using the wire as a guide. It's easier to push the hose from the carburettor side to the gas tank side, as you can grab the hose from the tank side and pull.

Now, instead of using a wire, use a 1/4" threaded rod in the hose. Preferably, use a 1/4" solid rod that is threaded 1/2" at the end, as the hose will slide better. At the threaded end, put a small 3/8"-7/16" OD washer with a 1/4" ID on the threaded end. Grind this washer down and keep it in your toolbox for future use. You want the OD of the washer to be smaller than the hose's OD. Then, thread a 1/4" hex nut on the end, and, if possible, grind the hex nut corners round. Now, pull the threaded rod out, and the hose will come with it. You will need to wiggle and move it around, and you will need to lift the plate under the flywheel up.

Using a wooden dowel to guide the new hose through

When replacing the fuel line on a Tecumseh engine, you may encounter some challenges due to the limited space and the need to navigate the new hose through various components. Here's a detailed guide on using a wooden dowel to guide the new hose through:

Before starting, ensure you have the correct size of fuel hose. For Tecumseh engines, the recommended size is 1/4" ID x 7/16" OD. It's important to note that standard automotive fuel hoses may not fit due to a larger outer diameter.

Now, let's begin the process of guiding the new hose through:

• Disconnect the old hose at the carburetor and the fuel tank.
• Insert a wooden dowel into the old hose. The dowel should be slightly longer than the hose to provide a good grip.
• Tape the old hose to the dowel using electrical tape. This will help create a smooth transition when pulling the new hose through.
• Cut the old hose and the new hose so that both ends are flat. This will ensure a better connection between the two hoses.
• Blow air through the old hose to remove any debris or residue. You can use an air compressor for this step.
• Connect the new hose to the old hose using a small amount of superglue. Hold the connection for a minute or two to ensure a secure bond.
• Pull the dowel, along with the old and new hoses, through the engine. Start from the carburetor side, as it's easier to grab the hose from the fuel tank side and pull.
• Use needle-nose pliers to grab the hose and pull it through. If needed, you can lift the plate under the flywheel for better access.
• Cut the old hose at the carburetor end to separate the new hose.
• Install the new hose, ensuring it is securely connected at both the carburetor and the fuel tank.

By using a wooden dowel, you can effectively guide the new hose through the engine, making the process of changing the fuel line connector on your Tecumseh engine more manageable.

Gluing the old and new hoses together

To glue the old and new hoses together, you will need to cut both ends of the hoses flat. Ensure they are dry by blowing into them with an air compressor. Use a strong adhesive such as super glue to join the old and new hoses, holding them together for a minute or two until the glue dries. This method, suggested by a user on the Snowblower Forum, is a great way to avoid the hassle of threading the new hose through.

Another user on the same forum suggests a different method for joining the old and new hoses. They recommend using a 1/4" threaded rod in the hose, preferably with a 1/2" thread at the end, as this will allow the hose to slide better. Place a small 3/8"-7/16" OD washer with a 1/4" ID on the threaded end, and grind it down before placing it in your toolbox for future use. Thread a 1/4" hex nut onto the end, and consider grinding the hex nut corners round to improve sliding. Pull the threaded rod out, and the hose will come with it. This method may require some wiggling and moving the hose around, and you will need to lift the plate under the flywheel.

A third method, suggested by a user on The Garage Journal, involves cutting the head off a 1/4" x 2" bolt and using it to join the old and new hoses. Tape the hoses together with electrical tape to give some extra holding power, ensuring that you don't make the joined section too fat.

Remember to use the correct size of fuel hose for your Tecumseh engine. The standard fuel hose sold in auto parts stores with a 1/4" ID and 1/2" OD will not fit. Instead, look for a hose with a 1/4" ID and 7/16" OD, which can be purchased at mower stores or on Amazon.

Using a 1/4 x 2 bolt to join the old and new hoses

To replace the fuel line on a Tecumseh engine, you will need to purchase a 1/4" x 2" bolt. This bolt will be used to join the old and new hoses together.

To begin, cut the head off the bolt, leaving a 2-inch-long piece. Next, tape the old and new fuel hoses together with electrical tape, ensuring that the connection is not too bulky. Now, feed the taped-together hoses through the engine, from the carburettor side to the tank side. This may require some force, but it is important to push and pull the hoses to get them through.

Once the hoses are through, separate them and thread the bolt through, reconnecting the old and new hoses. Tape the connection again for added security. Finally, cut the new hose to the correct length and attach it to the carburettor.
