Replacing Fuel Line On Cub Cadet: Step-By-Step Guide

The fuel line in a Cub Cadet allows fuel to travel from the tank to the carburetor and from the primer bulb to the fuel system. The product model number is essential to finding the correct Cub Cadet factory replacement part. The model number can be found on the left side of the Product Identification Label and may include numbers, letters, or hyphens. Cub Cadet offers a Right Part Pledge, which means that if you purchase the wrong part, they will work with you to identify the correct part and initiate a free exchange.

Finding the model number

To replace the fuel line on your Cub Cadet, you'll first need to find the model number to ensure you get the correct replacement part. The product's model number is eleven characters long and is printed on the left side of the Product Identification Label. The characters can include numbers, letters, or hyphens.

The location of the Product Identification Label varies by product type. Here's how to find the label and model number for different Cub Cadet products:

Push Mowers (Walk-Behind and Self-Propelled):

Look for the Product Identification Label on the rear left side of the product's cutting deck. The model number for push mowers will start with 11 or 12.

Riding Mowers (Lawn Tractor, Garden Tractor, RZT, and Commercial Zero-Turn):

For riding mowers, the Product Identification Label can be found on the underside of the seat pan. The model number for these will start with 13, 14, 17, or 53.

Garden Tillers (Rototillers):

The Product Identification Label is located on the surface of the tine housing. Garden tiller model numbers start with 21.

Two- and Three-Stage Snow Blowers (Snow Throwers):

You can find the Product Identification Label on the rear of the frame cover, between the wheels. The model number for two- and three-stage snow blowers will start with 31.

Single-Stage Snow Blowers (Snow Throwers):

The Product Identification Label is located on the right side of the frame. Like the two- and three-stage snow blowers, the model number for single-stage snow blowers will also start with 31.

Weed Whackers (String Trimmer, Whipper-Snipper):

The Product Identification Label can be found on the left or right side of the starter housing, or near the starter rope housing. Weed whacker model numbers will start with 41 or 42.

Removing the seat and fenders

To replace the fuel line on a Cub Cadet, you will need to remove the seat and unbolt the fenders from the footpads. Here is a step-by-step guide on how to do this:

Start by locating the seat and fenders on your Cub Cadet. The seat is the part you sit on, and the fenders are the coverings that protect the wheels. You may need to refer to your Cub Cadet's manual to familiarise yourself with the specific model's components. Once you have located these parts, gather the necessary tools, such as a wrench or screwdriver, to remove the bolts or screws holding them in place.

Next, carefully remove the seat by unscrewing or unbolting it from the tractor. Place the seat aside in a safe place, making sure it is out of the way of your work area. Now, locate the bolts that secure the fenders to the footpads. Using your tool of choice, carefully unbolt the fenders. Take your time with this step to avoid damaging the fenders or any other components. Once the fenders are loose, carefully lift and remove them, setting them aside with the seat.

With the seat and fenders removed, you should now have better access to the fuel line and other components of the Cub Cadet. It is important to keep track of the bolts or screws removed during this process to ensure proper reassembly. Additionally, be cautious of any fuel remaining in the tank or lines, as it may be flammable or create a mess if spilled.

Now that the seat and fenders are out of the way, you can continue with the next steps of replacing the fuel line, as outlined in other guides or manuals. Remember to exercise caution and follow safety procedures when working on any machinery or equipment.

Disconnecting the fuel tank

First, remove the seat and unbolt the fenders from the footpads. This will give you access to the fuel tank and the necessary components. Next, you will need to disconnect the fuel tank's low fuel sender. This component is responsible for sending a signal to the fuel gauge, indicating the fuel level in the tank. It is usually located near the fuel tank, and you can disconnect it by carefully detaching any wires or hoses connected to it. Once the low fuel sender is disconnected, you can proceed to the next step.

Now, you will need to drain the fuel tank. Make sure you place a suitable container underneath the tank to collect the drained fuel. Be extremely cautious during this step to avoid any spills or accidents. Completely draining the fuel tank will make it lighter and easier to work with. After draining the tank, move on to disconnecting the fuel line that leads from the tank to the engine. You can use a suitable tool to carefully detach the fuel line from the tank and engine. If you plan to replace the entire fuel line, you may cut it for easier removal.

With the fuel line disconnected, you can now lift and remove the fuel tank. Turn it upside down to access the valves and bungs. The valves can be removed by pulling and twisting them. The bungs are the rubber seals that sit at the bottom of the fuel tank. They may come out with the valves, but if they are rotten, they might rip and leave parts inside the tank. In such cases, you can remove the remaining parts through the filler opening. It is also a good idea to flush the tank if there is any debris or residue inside.

Finally, before reassembling the fuel tank, take the opportunity to clean it thoroughly and apply a thin layer of grease to the bungs and the fuel shut-off valve. This will help create a tight seal and prevent leaks. Make sure to follow the manufacturer's instructions and use compatible parts and materials when reassembling the fuel tank and installing the new fuel line.

Draining the tank

To replace the fuel line on a Cub Cadet, you will first need to drain the tank. This process will differ depending on the model of your Cub Cadet.

For the Cub Cadet 2284, start by removing the seat and unbolting the fenders from the footpads. Next, disconnect the fuel tank's low fuel sender and remove the fenders. Now, you can drain the tank and disconnect the line that leads to the engine. You can simply cut the line if you are also replacing the line from the tank to the engine.

For older Cub Cadets with plastic tanks, the process is much simpler as they only have one bung and the tank is easy to remove.

Lifting the tank out

First, ensure you have completed the necessary preliminary steps. This includes removing the seat, unbolting the fenders from the footpads, disconnecting the fuel tank low fuel sender, and draining the tank. It is also important to disconnect the line leading to the engine, and you may choose to cut the line if you are replacing it completely.

Once these steps are completed, you are ready to lift the tank out. Carefully lift the tank, being mindful of any remaining fuel or residue inside. Place the tank in a well-ventilated area where you have ample space to work on it. Turning the tank upside down is recommended, as it provides easier access to the valves and bungs.

The valves can be removed by pulling and twisting them. The bungs, which are located at the bottom of the fuel tank, may come out with the valves. However, if they are rotten, they may rip, leaving a portion still inside the tank. In such cases, you can remove the remaining part through the filler opening.

After lifting out the tank and exposing its underside, it is a good opportunity to flush the tank if there is any debris or residue inside. You can also clean the area where the tank was situated in the tractor.
