Replacing Ryobi Homelite Backpack Blower Carburetor Fuel Lines

If your leaf blower is not working properly, it may be time to replace the fuel lines and carburetor. Fuel lines can clog, crimp, or crack, restricting gas flow and preventing the engine from starting. This is a basic procedure that works for replacing fuel lines in a variety of leaf blower models, including Ryobi and Homelite products. The carburetor controls the mixture of fuel and oxygen going to the engine, and over time, it may become out of adjustment, causing the blower to lose power and run erratically. In this article, we will guide you through the steps to replace your leaf blower's fuel lines and carburetor, helping you get your equipment running like new again.

Remove the air filter cover

To remove the air filter cover, you'll need to first unscrew the retaining bolt. Then, gently pull the air filter cover away from the engine to remove it.

• Make sure you have gathered all the necessary tools before you begin. For this step, you will need a screwdriver.
• When removing the air filter cover, be careful not to misplace the retaining bolt. Keep it in a safe place, as you will need to reinstall it later.
• It is important to gently pull the air filter cover to avoid causing any damage to the surrounding components.
• Once the air filter cover is removed, set it aside in a safe place to ensure it doesn't get damaged or lost during the rest of the repair process.
• Take note of the orientation and positioning of the air filter cover as you remove it. This will help you reinstall it correctly later on.
• If you encounter any resistance or if the air filter cover seems stuck, double-check that you have completely unscrewed the retaining bolt and that there are no other components blocking its removal.

Disconnect the spark plug wire

To disconnect the spark plug wire from your Homelite backpack blower, you will need to locate the spark plug itself. This is a small cylindrical device found in the engine cylinder head. Once you have located the spark plug, you can use a spark plug socket and ratchet to remove it.

It is important to disconnect the spark plug wire to ensure that the blower cannot start while you are working on it. This is a crucial safety measure.

If your spark plug wire is broken, you will need to replace the ignition coil, as the spark plug wire is hardwired into the ignition coil. You can do this by unscrewing the wire from the ignition module and screwing in a new one. Alternatively, if the metal spark plug connector has disconnected from the spark plug wire, you can simply replace the connector.

When disconnecting and working with the spark plug wire, it is important to exercise caution and follow safety procedures to avoid injury.

Remove the blower tube

To remove the blower tube, start by locating the thumb screw on the front of the housing. Loosen this thumb screw and then pull the blower tube off.

If you're replacing the fuel lines, you'll need to remove the carburetor and the fuel tank. To do this, first, disconnect the spark plug wire to ensure the blower can't start accidentally. Then, remove the air filter cover by unscrewing the screws and lifting it off.

Next, remove the carburetor mounting screws and pull out the air box, releasing it from the carburetor throttle and choke levers. Take note of the configuration of the small and large fuel lines on the carburetor so you can reconnect them correctly later. Now, remove the fuel lines from the carburetor and then remove the carburetor from the engine.

After that, remove the carburetor adapter and air dam by unscrewing the screws. Finally, remove the fuel tank by unscrewing the screws from the front of the muffler guard cover and then lifting it off.

Remove the carburetor

To remove the carburetor from your Ryobi Homelite backpack blower, start by removing the air filter cover. Unscrew the retaining bolt and gently pull the air filter cover out. Next, remove the air filter base. Take out the two nuts holding the air filter base using a ratchet wrench, then remove the base.

Now, you need to remove the throttle cable from the carburetor. To do this, retract the throttle arm slightly to create some slack in the throttle cable, then remove it from the carburetor assembly.

Before removing the fuel lines from the carburetor, it is advisable to clamp them with fuel line clamps. If you don't have clamps, you can drain the fuel from the tank. Disconnect the fuel lines from the carburetor using a flathead screwdriver and/or long-nosed pliers.

Finally, you can remove the carburetor itself. Slide the carburetor assembly off the retaining bolts and away from the engine. Take the carburetor gasket from the heat dam assembly, or verify that it is still connected to the carburetor throttle plate.

Now that the carburetor has been removed, you can install a new one.

Remove the fuel tank

To remove the fuel tank from your Homelite backpack blower, you will need screwdrivers, hex drivers, fuel line clamps, and long-nose pliers.

First, remove the air filter cover by unscrewing the retaining bolt and lifting the cover from the engine. Next, clamp the fuel lines with fuel line clamps and use a flathead screwdriver and/or long-nose pliers to disconnect the fuel lines from the carburetor. It is advisable to clamp the fuel lines before removal. If you do not have fuel line clamps, you can drain the fuel from the tank.

Now, remove the three screws holding the gas tank to the engine and carefully lift the gas tank assembly from the engine.

At this point, you have successfully removed the fuel tank from your Homelite backpack blower and can proceed to install a new one if necessary. Remember to exercise caution when handling fuel and ensure proper ventilation during the process.
