Replacing Fuel Lines On Echo Weed Eater: A Step-By-Step Guide

If you're experiencing issues with your Echo weed eater, you may need to replace the fuel lines. This is a straightforward process that can be done at home with the right tools and some patience. The fuel lines in your weed eater can crack and leak over time due to the ethanol in the fuel, so it's important to replace them to keep your equipment running smoothly and avoid further damage. This repair is necessary when there is cracking in the purge valve, the fuel tank grommet is leaking, or the purge bulb is pulling excess air or no fuel when depressed. You can purchase an Echo Fuel Line Repower Kit, which includes all the necessary parts for this repair, such as the fuel lines, grommet, fuel filter, ventilator, purge bulb, and gas cap vent gasket.

Disconnect and remove fuel lines

Disconnecting and removing the fuel lines from your Echo weed eater is a straightforward process that can be completed in a few simple steps. Here is a detailed guide to help you through the process:

Firstly, make sure that the engine is cool and that there is little to no fuel left in the tank. This is an important safety precaution to prevent any accidental ignition during the process. Once the engine is cool, remove the wire and boot from the spark plug to further ensure that the engine does not start accidentally.

Now, you can begin to disconnect the fuel lines. Note the orientation of the fuel lines attached to the primer assembly, as it is important to keep the lines properly oriented during reassembly. After noting the orientation, carefully disconnect the fuel lines from the primer assembly. Be prepared for some fuel to spill out during this step.

After the fuel lines are disconnected, you can release the check valve and vent tube. Then, remove the mounting screws that secure the fuel tank and gently pull the tank off. With the tank removed, carefully pull out the fuel line assembly from the tank.

At this point, you can slide off the retaining ring and pull the fuel filter out of the old fuel line. Finally, pull the old fuel line out of the grommet, taking care not to damage the surrounding components.

By following these steps, you will have successfully disconnected and removed the fuel lines from your Echo weed eater. Remember to have a suitable receptacle for catching any spilled fuel and to work in a well-ventilated area. Now you are ready to install the new fuel lines and grommet, following the instructions provided with your replacement kit.

Remove the air filter

To remove the air filter from an Echo Trimmer, you will need to follow a few simple steps.

First, make sure the engine is cool and that there is little to no fuel left in the tank. Then, remove the wire and boot from the spark plug to prevent accidental engine ignition.

Now, you can begin to remove the air filter assembly. Loosen the thumb screw, which will allow you to remove the air cleaner lid and access the air filter. Take out the air filter, and you're done with this part!

It is important to maintain your air filter by frequently checking for obstructions, tears, or other damage. A well-maintained air filter will ensure your trimmer performs optimally and prevent dirt and debris from entering and damaging the engine.

Reattaching fuel lines

Once you have removed the old fuel lines and grommet, you can start the process of reattaching the new fuel lines.

Firstly, lightly coat the edge of the new grommet with 2-cycle engine oil. This will lubricate the grommet and make installation easier. You can then install the new grommet onto the fuel tank, pressing it into place with a screwdriver if necessary.

Next, cut the ends of the fuel lines at a similar angle to create tapered ends. This will allow the lines to slide more easily into the new grommet. Lightly coat the ends of the fuel lines with 2-cycle engine oil.

Now, you can start to insert the fuel lines into the grommet. Insert the fuel vent line into the grommet and feed any excess line into the fuel tank. Do the same with the incoming fuel line and the return fuel line.

Finally, reinstall the fuel filter. Insert a wire hook into the fuel tank and retrieve the incoming fuel line. Remove the angle that was added earlier with wire cutters or scissors, as the tube needs to be squarely cut to install the fuel filter. Slide the fuel line clip over the fuel line and hold it approximately 1/4 inch from the end of the tube. Install the fuel filter onto the end of the fuel line, ensuring the ring clip expands slightly to accommodate the flared connection before tightening.

Your new fuel lines are now reattached and you can move on to reassembling the unit.

Replacing the purge bulb

To replace the purge bulb on your Echo weed eater, you will need to purchase a replacement bulb. You can buy a purge bulb from Amazon, Home Depot, or directly from the Echo website.

Once you have your replacement bulb, follow these steps:

• Loosen the two screws holding the carburetor with a T27 Torx bit, turning it counter-clockwise.
• Remove the four screws holding the old purge bulb by turning them counter-clockwise.
• Remove the plate holding the purge bulb.
• Take out the old purge bulb and replace it with the new one, ensuring the rim of the new purge valve is properly seated.
• Reinstall the purge bulb plate and securely tighten the four screws. Be careful not to overtighten these screws, as they can easily strip.
• Reinstall the carburetor, air filter, and air filter housing in the same manner they were removed.

It is important to note that ethanol in the fuel will eventually cause this repair to be necessary, as it will crack the purge bulb. Using ethanol-free fuel, which is available at most hardware stores, will help prolong the life of your weed eater's fuel system components.

Replacing the vent cap gasket

The gas cap gasket forms a seal between the fuel cap and the fuel tank. As it is made of rubber, the gasket will eventually harden and crack. However, replacing the gasket is a very easy task.

Removing the gas cap gasket

• Remove the fuel cap from the fuel tank by unscrewing it and gently pulling on the cap lanyard.
• Remove the gas cap gasket by using a pick to pry the gasket from the inside of the fuel cap. Take the gasket off the fuel cap and lanyard.

Installing the new gas cap gasket

• Install the new gasket by sliding it over the fuel cap lanyard and placing it inside the fuel cap.
• Press around the edges of the gasket to ensure it is properly seated (above the threads) in the recess at the top of the fuel cap.

Reassembling the unit

Reinstall the fuel tank cap by placing the cap lanyard into the fuel tank and screwing the fuel cap back on.

You have now completed the reassembly and your trimmer should be ready for use.
