Replacing Ryobi Fuel Line: A Step-By-Step Guide

If you're looking to replace the fuel line on your Ryobi trimmer, you've come to the right place. This is a relatively simple fix that can be done at home with the right tools and parts. The fuel line is an essential part of your trimmer's fuel delivery system, transferring gas to the carburettor. Over time, the fuel return line can harden and crack, so regular maintenance and replacement are necessary to keep your trimmer in top condition. In this guide, we'll walk you through the process of replacing the fuel line, step by step, so you can get your trimmer running like new again.

Removing the fuel filter and line

The fuel filter and line on a Ryobi trimmer can be removed and replaced in a few simple steps. This process should be carried out when the fuel filter is dirty or when the fuel line is clogged or kinked. It is important to note that the fuel filter and line are integral parts of the trimmer, as they ensure that debris does not enter the carburetor and fuel system, which could lead to engine problems.

Step-by-Step Guide:

• Remove the rear cover: Unscrew and take off the rear cover of the engine.
• Detach the carburetor: Drain excess fuel from the fuel tank. Then, remove the screws, choke plate, and choke assembly from the carburetor. Disconnect the throttle cable using a lift-and-twist motion.
• Disconnect the incoming fuel line: Disconnect the fuel line from the carburetor inlet. You may need to use long-nosed pliers for this step. Push or pull the fuel line through the carburetor mounting plate.
• Remove the fuel filter: Pry away the plastic washer from the fuel filter/line outlet at the bottom of the fuel tank. Use wire cutters to cut the fuel filter/line outlet flush with the fuel tank. Next, use a small screwdriver to push the remaining fuel filter into the fuel tank. With the fuel tank cap removed, rotate the trimmer upside down until the fuel filter falls out.

Disconnecting the incoming fuel line

Firstly, you will need to remove the rear cover by unscrewing the four screws that hold it in place. Once the cover is removed, you can access the carburetor, which needs to be detached. Before detaching the carburetor, it is important to drain any excess fuel from the fuel tank to avoid spills or messes. Remove the two screws from the carburetor assembly and carefully detach the choke plate and choke assembly. The throttle cable is connected to the carburetor and needs to be disconnected using a lift-and-twist motion.

Now, you are ready to disconnect the incoming fuel line. This step may require the use of long-nosed pliers for a better grip. Gently pull the fuel line away from the carburetor inlet; it should come off relatively easily. If it is stuck, use the pliers to gently wiggle it loose without damaging the surrounding components. Once the fuel line is disconnected, push or pull it through the carburetor mounting plate to create some slack.

At this point, you can remove the fuel filter. Use a small screwdriver to pry the plastic washer away from the fuel filter/line outlet on the bottom of the fuel tank. Cut the fuel filter/line outlet as close to the fuel tank as possible using wire cutters or scissors. Gently push the remaining portion of the fuel filter into the fuel tank using the screwdriver. With the fuel tank cap removed, rotate the trimmer upside down, allowing the fuel filter to fall out.

Now that the incoming fuel line is disconnected from the carburetor and the fuel filter has been removed, you can proceed to the next steps of replacing the fuel line and filter. Remember to work carefully and use the appropriate tools to avoid damage to your equipment.

Removing the fuel filter

The fuel filter is located inside the fuel tank and is responsible for filtering out tiny particles and debris before they enter the carburetor. It is important to replace the fuel filter regularly to maintain the overall performance and longevity of your Ryobi trimmer. Here is a step-by-step guide on how to remove the fuel filter:

• Drain the fuel tank: Before beginning any work on your Ryobi trimmer, it is important to drain any excess fuel from the fuel tank. This will prevent spills and reduce the risk of fire.
• Remove the rear cover: Using a screwdriver, remove the four screws that hold the rear cover in place. Set the screws aside in a safe place so they do not get lost.
• Detach the carburetor: With the rear cover removed, you will now have access to the carburetor. Remove the two screws holding the carburetor assembly in place. Carefully lift the choke plate and choke assembly away from the carburetor.
• Disconnect the throttle cable: Using a lift-and-twist motion, disconnect the throttle cable from the carburetor. This will give you more room to work and allow you to fully detach the carburetor.
• Disconnect the incoming fuel line: The incoming fuel line is connected to the carburetor inlet. It should pull away relatively easily, but if necessary, use long-nosed pliers to gently disconnect it.
• Push or pull the fuel line through: With the carburetor disconnected, you can now push or pull the incoming fuel line through the carburetor mounting plate. This will give you access to the fuel filter.
• Remove the plastic washer: Using a small screwdriver, carefully pry the plastic washer away from the fuel filter/line outlet on the bottom of the fuel tank. Set the washer aside so it does not get lost.
• Cut the fuel line: Use wire cutters to cut the fuel filter/line outlet as close to the fuel tank as possible. Be careful not to damage the fuel tank itself.
• Remove the fuel filter: With a small screwdriver, gently press the remaining portion of the fuel filter into the fuel tank. Then, turn the trimmer upside down and shake it gently until the fuel filter falls out.

By following these steps, you will have successfully removed the fuel filter from your Ryobi trimmer. It is important to dispose of the old fuel filter properly and ensure that no debris remains in the fuel tank before installing a new fuel filter.

Installing the new fuel filter and line

Now that you've removed the old fuel filter and line, it's time to install the new ones. Here's a detailed guide on how to do it:

Firstly, use wire cutters to cut a taper at the end of the new fuel line. This will allow it to pass through the mounting hole more smoothly. It is important to lubricate the outside of the new fuel line with two-cycle engine oil. This will facilitate its passage through the mounting hole.

The next step is to insert the new fuel line into the fuel tank. Thread the tapered end of the line through the mounting hole at 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 screwdriver to press down on the centre of the fuel filter while simultaneously pulling steadily on the fuel line. Continue this motion until the fuel filter and line are fully seated within the mounting hole.

Now, slide the plastic washer onto the new fuel line. Use pliers to slide the washer over the fuel filter nipple, ensuring it is flush against the fuel tank. This step is important to secure the fuel filter in position.

Pass the tapered end of the fuel line through the opening at the back of the carburetor mounting assembly. Use cutters to remove the taper from the line, ensuring it is cut squarely for a proper connection to the carburetor.

Finally, reconnect the incoming fuel line to the carburetor inlet.

Reassembling the unit

Now that you have installed the new fuel filter and line, it's time to reassemble the unit. Here are the steps to follow:

Firstly, connect the throttle cable to the throttle linkage of the carburetor. Install the carburetor mounting screws onto the choke plate and lever. Secure the carburetor and choke plate to the engine using the screws provided. Ensure that the choke lever and the wavy washer are properly aligned before tightening the upper screw.

Finally, reinstall the rear cover onto the engine and secure it with the retaining screws.

Reassembling the unit

Now that you have installed the new fuel filter and line, it is time to reassemble the unit.

Firstly, reconnect the incoming fuel line to the carburetor inlet. Ensure that the line is securely connected to the carburetor.

Next, reinstall the carburetor. Connect the throttle cable to the throttle linkage of the carburetor. Install the carburetor mounting screws onto the choke plate and lever. Secure the carburetor and choke plate to the engine using the screws provided. It is important to ensure that the choke lever and the wavy washer are properly aligned before tightening the upper screw.

Finally, reinstall the rear cover. Place the rear cover back onto the engine and secure it with the four screws that were previously removed.

By following these steps, you will have successfully replaced the fuel filter and line on your Ryobi trimmer, ensuring optimal performance and longevity for your equipment.
