Replacing The Fuel Line On Your Ryobi 30Cc Trimmer

If you're looking to replace the fuel line on your Ryobi 30 cc trimmer, you've come to the right place. This is a step-by-step guide on how to get it done and have your trimmer running like new again. But before we begin, a word of caution: always exercise extreme caution when handling fuel and ensure your work area is well-ventilated. Now, let's get started!

Removing the rear cover

To remove the rear cover of your Ryobi 30 cc trimmer, you will need a screwdriver.

First, remove the four screws from the rear cover. Once the screws have been removed, carefully lift the rear cover away from the engine. Be cautious not to lose any small parts, such as washers, and keep the screws safe so you can securely replace the cover later.

Now that the rear cover is removed, you can access the carburetor and fuel lines. Before proceeding with any further repairs or maintenance, ensure that you drain any excess fuel from the fuel tank to avoid any accidental spills.

If you need to access the fuel filter, you can do so by prying away the plastic washer from the fuel filter/line outlet on the bottom of the fuel tank. You can then use wire cutters to cut the fuel filter/line outlet flush with the tank. Finally, use a small screwdriver to push the remaining part of the fuel filter into the tank and turn the trimmer upside down to allow the filter to fall out.

Disconnecting the carburetor

Drain the Fuel Tank:

Before starting any work on the carburetor, it is essential to drain any excess fuel from the fuel tank. This is a safety precaution to prevent spills and reduce the risk of fire. Make sure to drain the fuel into an approved container.

Remove the Air Filter Cover:

Locate and remove the air filter/muffler cover, which is held in place by four retaining screws. Clean the air filter in warm, soapy water and let it dry before proceeding to the next step.

Detach the Carburetor Assembly:

Using a screwdriver, remove the two carburetor mounting screws located just above and below the air filter. Once the screws are removed, carefully pull off the choke lever and metal plate. If your Ryobi trimmer has limiter caps on the carburetor, make sure to remove them as well.

Disconnect the Fuel Lines:

With the carburetor exposed, use needle-nose pliers to carefully unhook both the incoming fuel line (also known as the primary fuel line) and the return fuel line (also known as the output fuel line) from the carburetor's nozzles. Gently pull the fuel lines away from the carburetor to avoid any damage.

Remove the Fuel Filter:

If you need to replace the fuel filter, now is the time to do it. Open the gas cap and reach into the tank with the needle-nose pliers to pull out the fuel filter. You may need to cut the fuel line attached to the filter using wire cutters or scissors.

By following these steps, you will have successfully disconnected the carburetor and prepared it for the installation of a new fuel line on your Ryobi 30 cc trimmer. Remember to work carefully and refer to the specific model's manual for additional instructions or variations.

Disconnecting the incoming fuel line

To disconnect the incoming fuel line from your Ryobi 30 cc trimmer, you will need a receptacle for draining fuel, long-nose pliers, a screwdriver, and a pair of cutters or scissors.

First, drain any excess fuel from the fuel tank. Next, disconnect the incoming fuel line from the carburetor. The line should pull away from the carburetor inlet easily, but you can use long-nose pliers if you need to. Now, push or pull the fuel line through the carburetor mounting plate.

You can now cut the fuel line with a pair of cutters or scissors, ensuring it is cut flush with the fuel tank. Then, use a screwdriver to push the remaining piece of the fuel line back into the fuel tank. Finally, rotate the trimmer upside down until the fuel filter falls out of the tank.

Removing the fuel filter

To remove the fuel filter from your Ryobi 30 cc trimmer, you will need a screwdriver, wire cutters, and a receptacle for draining fuel.

First, drain any excess fuel from the fuel tank. Next, remove the rear cover by taking out the four screws and detaching it from the engine. Then, disconnect the throttle cable from the carburetor using a lift-and-twist motion. Now, you can disconnect the incoming fuel line from the carburetor inlet. It should pull away relatively easily, but you can use long-nosed pliers if necessary.

At this point, you can remove the fuel filter. Pry the plastic washer away from the fuel filter/line outlet on the bottom of the fuel tank. Then, use wire cutters to cut the fuel filter/line outlet flush with the fuel tank. Afterward, use a small screwdriver to push the remainder of the fuel filter into the fuel tank. Finally, with the fuel tank cap removed, rotate the trimmer upside down until the fuel filter falls out of the fuel tank.

Reinstalling the carburetor

Now that you have successfully removed the carburetor, it's time to install the new fuel filter and line.

Firstly, use wire cutters to cut a taper at the end of the new fuel line. This will allow the line to pass through the mounting hole more smoothly. Next, lubricate the outside of the new fuel line with two-cycle engine oil. This will help the line pass through the mounting hole with ease. Once you have done this, 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.

At this stage, you will need a large screwdriver. Use it to press down on the centre (plastic) portion of the fuel filter while simultaneously 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. Once this is done, slide the plastic washer onto the new fuel line and use pliers to slide the plastic washer over the fuel filter nipple (flush against the fuel tank). This will secure the fuel filter in position.

Now, pass the tapered end of the fuel line through the opening in the back of the carburetor mounting assembly. Use cutters to remove the taper from the line. It is important that the line is cut squarely for a proper connection to the carburetor. Finally, reconnect the incoming fuel line to the carburetor inlet.

You can now reinstall the carburetor. To do this, connect the throttle cable onto 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 with the two screws. It is important to note that the choke lever and the wavy washer must be properly aligned before tightening the upper screw.
