Disconnect the old fuel line

To disconnect the old fuel line on your Weed Eater SST25CE, you will need to identify the fuel line routing. Typically, there are three fuel lines connected to the carburetor and primer bulb.

Firstly, locate the fuel lines coming out of the fuel tank. One line, which has a fuel filter at the end, connects to the bottom fitting on the carburetor. This is usually the smaller diameter line. The second line, which is the larger diameter line, also comes out of the tank and connects to the bottom fitting on the primer bulb.

Now, to disconnect the old fuel line, follow these steps:

• Using your fingers or a small flat-head screwdriver, carefully pry off the fuel line from the bottom fitting of the carburetor. Be gentle to avoid damaging the fitting.
• Repeat the process for the fuel line connected to the primer bulb.
• Next, locate the third fuel line, which goes from the top fitting of the primer bulb to the top fitting on the carburetor. Again, use your fingers or a small flat-head screwdriver to gently pry off the fuel line from both fittings.
• Once all the fuel lines are disconnected, set them aside, ensuring they do not come into contact with any sharp objects to prevent damage.
• Before installing the new fuel lines, inspect the fittings on the carburetor and primer bulb for any signs of damage or debris. Clean or replace them if necessary.

Remember to wear protective gear, such as gloves and eye protection, when working with fuel lines to avoid any injuries or accidents.

Connect the new fuel line

To connect the new fuel line, start by identifying the correct routing for your fuel line. The typical setup for a Weedeater SST25CE involves three lines:

• One line (with the fuel filter at the end) comes out of the fuel tank and goes to the bottom fitting on the carburetor.
• The second line comes out of the tank and goes to the bottom fitting on the primer bulb.
• The third line goes from the top fitting on the primer bulb to the top fitting on the carburetor.

Once you have identified the correct routing, follow these steps:

• Disconnect the old fuel line from the fittings on the carburetor and primer bulb. Be sure to also remove the fuel filter from the line that connects to the carburetor.
• Cut the new fuel line to the appropriate length, if necessary. You can use the old fuel line as a reference for the correct length.
• Install the new fuel filter onto the line that will connect to the carburetor. Make sure the filter is securely attached to the line.
• Connect one end of the new fuel line to the bottom fitting of the carburetor. Ensure that the connection is secure and tight.
• Connect the other end of the same fuel line to the fuel tank. Again, ensure a secure and tight connection.
• Connect one end of the second fuel line to the bottom fitting of the primer bulb.
• Connect the other end of the second fuel line to the fuel tank. Ensure all connections are tight to prevent leaks.
• Connect one end of the third fuel line to the top fitting of the primer bulb.
• Connect the other end of the third fuel line to the top fitting of the carburetor.

Once all the connections are made, check for any signs of leaks before starting the engine. If you notice any leaks, tighten the connections as needed.

It is important to note that fuel lines should be replaced periodically, as they can deteriorate over time and develop cracks or splits. Always refer to the official Weedeater SST25CE manual or seek professional assistance if you are unsure about any steps in the process.

Check for leaks

To check for leaks in your Weed Eater SST25CE, start by inspecting the fuel lines for any cracks or splits. Fuel lines tend to deteriorate over time, so if your trimmer is a few years old, it might be a good idea to replace them.

Next, check the primer bulb for any cracks, as well as the two screws that hold it in place. Make sure the screws are tight, and inspect the fuel lines connected to the primer bulb for any signs of damage.

Also, check the fuel tank cap, carburetor seals, and the fuel tank itself for any damage that could lead to leaks.

If you find any cracks or splits in the fuel lines, primer bulb, or fuel tank, replace them. Additionally, if the carburetor seals or fuel tank cap are damaged, they will need to be replaced as well.

Finally, check the piston rings and spark plug for wear or damage. If the piston rings are worn, the engine may leak gas. A faulty spark plug can also cause the engine to leak gas, as it can lead to an improper air-fuel mixture.
