What You'll Learn
Replacing the fuel filter and line
To replace the fuel filter and line on your Ryobi 4-cycle blower, you will need a receptacle for draining fuel, Phillip's/Torx drivers, 2-cycle engine oil, a large screwdriver, cutters or scissors, and long-nosed pliers. The process should take around 15 minutes.
First, remove the rear cover of the engine by taking out the four screws. Next, drain the fuel from the tank using your chosen receptacle. Now, lubricate the outside of the new fuel line with 2-cycle engine oil. This will allow the line to pass through the mounting hole more smoothly. Insert the new fuel line into the fuel tank and thread the tapered end through the mounting hole in the bottom of the tank. Pull the fuel line through the opening until the fuel filter nipple is partially seated in the mounting hole.
Use a large screwdriver to press down on the centre, plastic portion of the fuel filter while pulling firmly and steadily on the fuel line from the bottom. Continue this motion until the fuel filter/line is fully seated within the mounting hole. Slide the plastic washer onto the new fuel line and use pliers to slide it over the fuel filter nipple, ensuring it is flush against the fuel tank. This will secure the fuel filter in position. Finally, pass the tapered end of the fuel line through the opening in the back of the carburettor mounting assembly.
Now, reconnect the incoming fuel line to the carburettor inlet. Reinstall the carburettor and connect the throttle cable to the throttle linkage. Install the carburettor mounting screws onto the choke plate and lever, ensuring that the choke lever and wavy washer are properly aligned before tightening the upper screw. Secure the carburettor and choke plate to the engine with the screws. Finally, reinstall the rear cover onto the engine and secure it with the four screws.

Reassembling the unit
When reassembling the unit, ensure that the choke lever and the wavy washer are properly aligned before tightening the upper screw. Reinstall the carburettor and connect the throttle cable to the throttle linkage of the carburettor. Install the carburettor mounting screws onto the choke plate and lever. Secure the carburettor and the choke plate to the engine with the screws.
Reinstall the rear cover onto the engine and secure it with the screws. You can now reconnect the incoming fuel line to the carburettor inlet.
If you have a "local primer" carburettor, the primer bulb will be built on top of the carburettor assembly. The bulb pulls fuel through the filtered fuel line and into the carburettor, and then pushes it out of the carburettor through the unfiltered return line.
If you have a "remote primer" carburettor, the primer assembly is separate from the carburettor body. The primer assembly needs to pull fuel through the carburettor, not push the fuel into it.
You can purchase a Ryobi Fuel Line Kit to help with the reassembly process.

Lubricating the new fuel line
Before you begin lubricating, it's important to have the right tools and materials on hand. You'll need two-cycle engine oil, a large screwdriver, and long-nosed pliers. You may also want to have a receptacle for draining fuel and cutters or scissors, as there might be a need to remove the old fuel line and prepare the new one.
To start, ensure that the new fuel line is properly sized and compatible with your Ryobi 4-cycle blower. You can refer to the product manual or seek advice from a specialist if you're unsure. Once you have the correct fuel line, apply a generous amount of two-cycle engine oil to its outer surface. This lubrication will make it easier for the line to pass through the mounting hole and prevent unnecessary friction or damage during installation.
After lubricating the fuel line, you can begin the installation process. Insert the tapered end of the line into the fuel tank and guide it through the mounting hole at the bottom. Gently pull the fuel line through, ensuring that the fuel filter nipple is securely seated in the mounting hole. Use your screwdriver to apply gentle pressure to the centre of the fuel filter while simultaneously pulling the line downwards. This will help seat the filter and line properly within the mounting hole.
The next step is to secure the fuel filter in place. Take the plastic washer and slide it over the fuel filter nipple, ensuring it sits flush against the fuel tank. You can use the long-nosed pliers to adjust the washer if needed. With the washer in place, the fuel filter will be securely held in position.
Finally, connect the tapered end of the fuel line to the carburetor mounting assembly. Ensure that all connections are tight and secure before starting your Ryobi 4-cycle blower. Remember to follow any additional safety guidelines provided by the manufacturer for fuel line installation and maintenance.

Testing the fuel line orientation
Step 1: Prepare the Necessary Items
Before beginning the testing process, ensure you have the following items:
- Protective gear, including gloves and safety glasses, to safeguard your hands and eyes from fuel and debris.
- Fresh fuel that is compatible with your Ryobi leaf blower model. Using the wrong type of fuel can lead to leaks or damage.
- A well-ventilated workspace to prevent the buildup of harmful fuel vapors.
Step 2: Understand the Carburetor Design
There are two common carburetor designs found in 2-cycle engines: "local primer" carburetors and "remote primer" carburetors. "Local primer" carburetors have the primer bulb built on top of the carburetor, while "remote primer" carburetors feature primer assemblies that are separate from the carburetor. Understanding the design of your carburetor will help you determine the correct fuel line routing.
Step 3: Test the Fuel Line Orientation
Now, you can perform the test to confirm the correct orientation of the fuel lines:
- Attach the fuel lines to the primer assembly, ensuring that the lines are connected to the correct input and output sides.
- Submerge the ends of both fuel lines in 2-cycle fuel. Never use water for this test.
- Prime the bulb.
- Observe the fuel lines. If bubbles emerge from the line without the fuel filter, the orientation is correct.
- If bubbles appear in the line with the fuel filter, the lines are installed incorrectly.
Step 4: Repeat the Test if Needed
In case the initial test indicates incorrect installation, reverse the lines and perform the test again. This step may need to be repeated until the correct orientation is achieved.
Step 5: Complete the Installation
Once you have confirmed the correct fuel line orientation, proceed with the rest of the installation process. This may include securing the fuel lines, reinstalling the carburetor, and connecting the necessary components.
Remember to consult a qualified technician or a detailed repair guide for specific instructions pertaining to your Ryobi 4-cycle blower model.

Using a Ryobi Fuel Line Kit
The Ryobi Fuel Line Kit is an easy and quick fix to ensure your trimmer or blower is running smoothly. The kit includes a 7-inch and a 10.5-inch clear fuel line, a fuel filter, two primer bulbs, an installation removal tool, and a manual.
To use the kit, start by removing the rear cover of your equipment. Remove the four screws from the rear cover. Next, lubricate the outside of the new fuel line with two-cycle engine oil. This will help the line pass through the mounting hole smoothly. Insert the new fuel line into the fuel tank and thread the tapered end through the mounting hole at the bottom of the tank. Pull the fuel line through the opening, so the fuel filter nipple is partially seated in the mounting hole.
Now, use a large screwdriver to press down on the centre, plastic portion of the fuel filter, while simultaneously pulling firmly on the fuel line from the bottom. Keep doing this until the fuel filter and line are fully seated in the mounting hole. Then, slide the plastic washer onto the new fuel line, using pliers to get it over the fuel filter nipple, right up against the fuel tank. This will secure the fuel filter in place. Finally, pass the tapered end of the fuel line through the opening in the back of the carburettor mounting assembly.
The kit is compatible with RYOBI, Homelite, and Toro Trimmers and Blowers.
