Replacing Fuel Lines In Your Ryobi Leaf Blower

If you're looking to replace the fuel lines on your Ryobi 4-cycle leaf blower, you've come to the right place. This is a step-by-step guide on how to get the job done safely and efficiently. First, it is important to note that fuel lines can clog, crimp, or crack, restricting gas flow and preventing the engine from starting. Before beginning any work, ensure you have the necessary tools and safety equipment and that you understand all the steps. To start, drain the fuel tank in a well-ventilated area and disconnect the spark plug wire to ensure the leaf blower can't start accidentally. Next, remove the blower tube, air filter cover, carburetor, and fuel tank. When removing the carburetor, note the configuration of the small and large fuel lines so that you can reconnect them correctly later. Now, pull the fuel lines out of the tank, taking care to remove the fuel filter from the small fuel line. Cut the new large fuel line at an angle and push it into the tank through the mounting hole. Grab the end of the line through the mouth opening with needle-nose pliers, then cut the angled end square and install the grommet. Tug the opposite end of the line to position the grommet, and cut the line to the same length as the original. Repeat this process for the small fuel line, ensuring the fuel filter is attached. Now, reinstall the left side of the housing, making sure to thread the fuel lines through the hole near the carburetor. Reinstall the guard cover on the muffler and the fuel cap. Finally, push the fuel lines onto the proper connections on the carburetor and reinstall the carburetor, air filter cover, and blower tube. Reconnect the spark plug wire, and you're done!

Remove the rear cover

To remove the rear cover of your Ryobi 4-cycle leaf blower, you will need a screwdriver.

First, locate the screws holding the rear cover in place. There should be four screws. Use your screwdriver to remove them. Once the screws have been removed, carefully lift the rear cover away from the engine. Set it aside in a safe place so that you can access it easily when it's time to reassemble your blower.

Now that the rear cover is removed, you can access the carburetor and fuel lines. Before proceeding, it is important to drain any excess fuel from the fuel tank to prevent spills. You can do this by removing the fuel tank cap and pouring the fuel into an approved storage container.

Next, you will need to disconnect the carburetor. Start by removing the two screws holding the carburetor assembly in place. Then, remove the choke plate and choke assembly. Finally, disconnect the throttle cable from the carburetor using a lift-and-twist motion.

With the carburetor disconnected, you can now access the fuel lines for replacement.

Disconnect the carburetor

To disconnect the carburetor of your Ryobi 4-cycle leaf blower, you will need a flathead screwdriver and/or long-nosed pliers.

First, clamp the fuel lines with fuel line clamps. If you don't have fuel line clamps, you can drain the fuel from the fuel tank. Disconnecting the fuel lines from the carburettor can be done with a flathead screwdriver and/or long-nosed pliers. It is important to note the configuration of the small and large fuel lines on the carburettor so that you can reconnect them correctly later.

To disconnect the carburettor itself, remove the carburettor mounting screws and pull out the air box, releasing it from the carburettor throttle and choke levers. You can then remove the entire carburettor from the engine.

Before disconnecting the carburettor, it is important to drain any excess fuel from the fuel tank.

Disconnect the fuel line

To disconnect the fuel line of your Ryobi 4-cycle leaf blower, you will need a flathead screwdriver and/or long-nosed pliers. It is advisable to clamp the fuel lines with fuel line clamps before disconnecting them. If you do not have fuel line clamps, you can drain the fuel from the fuel tank.

To begin, locate the fuel lines on the carburetor. There should be two fuel lines, one small and one large. The small fuel line is connected to the fuel filter inside the tank. Use needle-nose pliers to remove the fuel filter from the mouth of the tank and then detach it from the end of the small fuel line.

Next, use your flathead screwdriver and/or long-nosed pliers to carefully disconnect the fuel lines from the carburetor. The lines should pull away from the carburetor inlet relatively easily, but you may need to use your tools to loosen them. Once the lines are disconnected, push or pull them through the carburetor mounting plate.

If you are only replacing the small fuel line, you can skip this next step. If you are replacing the large fuel line or both lines, you will need to remove the large fuel line from the tank. To do this, push the large fuel line into the tank through the mounting hole and pull it out through the mouth of the tank.

Now that the fuel lines are disconnected, you can proceed to install the new fuel lines.

Remove the fuel filter

To remove the fuel filter from your Ryobi 4-cycle leaf blower, you will need a receptacle for draining fuel, a screwdriver, and long-nose pliers.

First, remove the fuel cap from the fuel tank. Next, you will need to remove the fuel filter from the fuel line. You can do this by inserting a wire hook into the fuel tank to retrieve the line containing the fuel filter. Then, remove the fuel filter from the fuel line with a twisting and pulling motion.

Now, you will need to remove the fuel filter from the fuel tank. To do this, 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. Finally, use a small screwdriver to press the remainder of the fuel filter into the fuel tank. With the fuel tank cap removed, rotate the blower upside down until the fuel filter falls out.

Install the new fuel filter

To install the new fuel filter for your Ryobi 4-cycle leaf blower, follow these steps:

First, use wire cutters to cut a taper at the end of the new fuel line. This will make it easier to pass the line through the mounting hole. Next, lubricate the outside of the new fuel line with two-cycle engine oil. This will help the line pass through the mounting hole more smoothly.

Now, 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 large screwdriver to press down on the centre (plastic) portion of the fuel filter while pulling firmly and steadily on the fuel line. Continue this motion until the fuel filter and line are fully seated within the mounting hole.

Next, 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 secures the fuel filter in position.

Finally, 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.

Your new fuel filter is now installed!
