Replacing Ryobi Weed Eater Fuel Line: Step-By-Step Guide

If you're looking to replace the fuel line on your Ryobi weed eater, you've come to the right place. This is a relatively easy fix that you can do yourself, and it will save you time and money. The fuel line is an essential part of your weed eater's fuel delivery system, transferring gas to the carburetor. If it gets clogged or kinked, it can starve your carburetor of the proper fuel and air mixture, leading to engine problems. By following these step-by-step guides, you can replace your fuel line and get your weed eater running like new again.

Removing the rear cover

To remove the rear cover of your Ryobi weed eater, you will need a screwdriver.

First, remove the four screws from the rear cover. You can do this by using a screwdriver to unscrew them. Once the screws have been removed, you can lift the rear cover away from the engine.

It is important to note that before you begin any work on your weed eater, you should drain any excess fuel from the fuel tank. This will help to prevent any spills or accidents during the removal and installation process.

Additionally, it is always a good idea to keep your fuel lines free of bad or old gas. This can be done by regularly replacing the fuel lines and ensuring that only freshly mixed unleaded fuel and high-quality, two-cycle engine oil are used. This will help to maintain the maximum performance of your engine.

Disconnecting the carburetor

Drain the Fuel Tank: Before beginning any work on the carburetor or fuel lines, it is essential to drain any excess fuel from the fuel tank. This is a safety precaution to prevent spills or leaks during the disassembly process.

Remove the Air Filter and Air Filter Housing: To access the carburetor, you will need to remove the air filter and its housing. First, remove the air filter cover, then take out the air filter itself. Next, locate and remove the screws that attach the air filter housing to the engine frame. Gently pull the housing away from the engine block.

Detach the Carburetor: With the air filter housing removed, you will now have access to the carburetor. Locate the two screws that secure the carburetor to the frame and remove them. Gently pull the carburetor away from the engine block. Be careful not to damage any surrounding components.

Disconnect the Fuel Lines: At this point, you should see the fuel lines connected to the carburetor. Gently remove both the input and output fuel lines from the carburetor. You may need to use a screwdriver or needle-nose pliers to carefully detach the lines without damaging them.

Cut and Remove the Old Fuel Lines: Once the fuel lines are disconnected from the carburetor, you will need to cut and remove the old lines from the fuel tank. Use cutting pliers to cut the lines flush with the tank. Then, use a screwdriver to push the remaining line stubs into the tank. Shake the weed eater gently to ensure that any loose parts of the line fall out of the tank.

Clean and Prepare the Area: Before installing the new fuel lines, take the opportunity to clean the area around the carburetor and fuel tank. Ensure that there is no dirt, debris, or residue that could contaminate the new fuel lines or affect the performance of the weed eater.

By following these steps, you will have successfully disconnected the carburetor and prepared your Ryobi weed eater for a new fuel line installation. Remember to work carefully and patiently, as fuel systems can be delicate, and always refer to your owner's manual or seek professional advice if you are unsure about any part of the process.

Detaching the fuel filter

To detach the fuel filter from your Ryobi weed eater, 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 unscrewing the four screws and taking off the cover. Then, disconnect the throttle cable from the carburetor using a lift-and-twist motion. Now, 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 push or pull the incoming fuel line through the carburetor mounting plate. Now, you can remove the fuel filter. Pry the plastic washer away from the fuel filter/line outlet on 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 press 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.

Installing the new fuel filter

To install the new fuel filter, you will need a new fuel line, wire cutters, two-cycle engine oil, and a large screwdriver.

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 also help the line to pass through the mounting hole more smoothly.

Now, insert the new fuel line into the fuel tank and thread the tapered end of the line 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. Continue this motion until the fuel filter/line is fully seated within the mounting hole.

Next, slide the plastic washer onto the new fuel line. Use pliers to slide the plastic washer over the fuel filter nipple, flush against the fuel tank. This secures the fuel filter in position.

Finally, 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 (the line must be cut squarely for proper connection to the carburetor).

Reassembling the unit

Now that you've replaced the fuel line, it's time to reassemble your Ryobi weed eater. Here's a detailed guide on how to do it:

• Connect the throttle cable to the throttle linkage of the carburetor. Ensure it is securely attached.
• Install the carburetor mounting screws onto the choke plate and lever. This will secure the carburetor and choke plate in place. Make sure that the choke lever and the wavy washer are properly aligned before tightening the upper screw.
• Reinstall the rear cover onto the engine. This will protect the internal components and ensure the smooth operation of your weed eater. Secure the rear cover with the screws you removed earlier.
• Ensure that all components are securely fastened and tightened before starting your weed eater.
• Before starting, check the fuel level and ensure that your weed eater is ready for operation.
• Once everything is in place, start your Ryobi weed eater and let it run for a few minutes to ensure that it is functioning correctly.
• If your weed eater is running smoothly, you have successfully replaced the fuel line and reassembled the unit!

By following these steps, you can confidently reassemble your Ryobi weed eater and get back to work. Remember to be cautious when handling any equipment and always wear the appropriate safety gear.
