How to Change Fuel Tank Assembly on Ryobi String Trimmer

Identify the correct replacement tank

Before you start replacing the fuel tank on your Ryobi string trimmer, it is important to identify the correct replacement tank. There are several reasons why you might need to replace the fuel tank, including a broken gas tank or fuel lines that need replacing.

To identify the correct replacement tank, you should first determine the specific model of your Ryobi string trimmer. This can be done by locating the model number on the product or its packaging. Once you have the model number, you can visit the Ryobi replacement parts page or a similar website to search for the corresponding replacement fuel tank.

Additionally, you can refer to the part number of the fuel tank to ensure you purchase the correct replacement. The part number can usually be found on the fuel tank itself or in the product manual. It is important to match the part number exactly to ensure compatibility.

Another factor to consider when identifying the correct replacement tank is the inclusion of fuel lines. Ryobi typically includes fuel lines with the gas tank, so it may be more convenient to replace the entire gas tank assembly rather than just the fuel lines. This will save you time and effort in the replacement process.

By following these steps and considering your specific model and part number, you can identify the correct replacement fuel tank for your Ryobi string trimmer. This will ensure a smooth and successful replacement process.

Remove fuel lines and motor housing

To remove the fuel lines and motor housing on your Ryobi string trimmer, follow these steps:

First, remove the fuel lines. Before you begin, clamp each line to prevent fuel from spilling. Use a flat-head screwdriver to pop the lines off the nipples. You can also use long-nose pliers to disconnect the fuel lines from the carburetor inlet. Once the lines are disconnected, push or pull them through the carburetor mounting plate.

Next, remove the motor housing. Remove the screws that hold the black housing to the trimmer motor. Be careful to keep debris out of the engine's crankcase. With the housing removed, you can now slide the fuel tank away from the trimmer.

Now that the fuel tank is removed, you can identify the filtered fuel line. Move each fuel line back and forth while watching the filter inside the tank to determine which line is connected to the filter.

Finally, prepare to install the new fuel tank. Slide the new fuel tank into place, ensuring that the trimmer's rubber mounts align with the slots on the tank. Reinstall the motor housing and reconnect the fuel lines. The filtered line should attach to the incoming side of the carburetor, while the non-filtered line should connect to the return side.

By following these steps, you can safely and effectively remove the fuel lines and motor housing on your Ryobi string trimmer.

Slide out the old tank

To slide out the old tank, you will need to first remove the fuel lines and the motor housing.

Before you begin, clamp each line to prevent fuel from spilling and use a flat-head screwdriver to pop the lines off the nipples. Once the fuel lines are removed, carefully remove the screws that hold the black housing to the trimmer motor. Be careful to keep debris out of the engine's crankcase.

Now, you can slide the old tank away from the trimmer. It is important to be gentle and careful during this process to avoid any damage to the engine or other components.

Additionally, if you are planning to reuse the fuel, ensure that you drain and store it in a safe container before proceeding with the tank removal.

Identify the filtered fuel line

Identifying the filtered fuel line is an important step in replacing the fuel tank on a Ryobi string trimmer. Here is a detailed guide to help you with this process:

Before installing the new fuel tank, you need to identify which fuel line is attached to the fuel filter. This is a crucial step to ensure that the fuel lines are connected correctly during reassembly. Start by locating the fuel filter inside the gas tank. Then, move each fuel line back and forth while observing the filter. The line that causes movement or vibration in the filter is the one attached to it.

Additionally, you can refer to the fuel line diagram that you created during the disassembly process. This diagram should show where the line with the filter attaches to the carburetor, helping you confirm which line is the filtered fuel line.

It is important to take your time during this step to avoid confusion when reconnecting the fuel lines. Once you have identified the filtered fuel line, you can proceed to the next steps of mounting the new tank and reconnecting the fuel lines correctly.

Remember to exercise caution when working with fuel, and ensure that you have clamped the fuel lines to prevent any spilling during the process.

Mount the new tank

To mount the new tank, first identify which fuel line is attached to the fuel filter. You can do this by moving each fuel line back and forth while watching the filter inside the gas tank to determine which line connects to the filter. The fuel filter is mounted inside the trimmer's fuel tank and its purpose is to filter out tiny particles and debris before they can enter the carburettor.

Once you have identified the correct fuel line, slide the new fuel tank back into place so the trimmer's rubber mounts align with the slots on the tank. Reinstall the motor housing.

Now you can reconnect the fuel lines. The filtered line should attach to the incoming side of the carburettor, and the non-filtered line should attach to the return side. If you are unsure of how the fuel lines should attach to the carburettor, you can refer to the article "How to Replace Fuel Lines on 2-Cycle Engines".
