Replacing Fuel Filter: Stihl Weedeater Maintenance Guide

If your Stihl weed eater is difficult to start or stalls often, it may be time to change the fuel filter. The fuel filter is located inside the fuel tank on the end of the incoming fuel line. To change the fuel filter, you will need to remove the spark plug wire boot and set it aside, remove the fuel cap, siphon the fuel from the tank, locate the fuel line, pull out the old fuel filter, push the new fuel filter into the fuel line, and then push the fuel filter into the fuel tank.

How to Change the Fuel Filter on a Stihl Weed Eater

The fuel filter is on the end of the fuel line inside the tank

To change the fuel filter on a Stihl weed eater, you'll first need to locate the spark plug and plug wire. The spark plug is near the top rear of the trimmer engine housing, and the spark plug wire boot connects to the top of the plug. Remove the spark plug wire boot by pulling it off the spark plug and bending the wire to the side. This prevents the spark plug from accidentally being activated during the fuel filter change.

Next, you'll need to access the fuel tank. To do this, twist the fuel cap counterclockwise and remove it. If the fuel tank is not empty, siphon the remaining fuel into a separate container with a hand siphon. Properly dispose of the fuel.

Now, look inside the fuel tank for the fuel line. You should see that the fuel filter is attached to the end of the fuel line inside the tank. You may need to tilt the trimmer to move the fuel line closer to the tank opening. Use needle-nose pliers to grasp the end of the fuel line and pull the fuel filter out of the tank.

Once the fuel filter is out, hold the fuel line in one hand and pull the fuel filter off the end of the line with your other hand. Then, take the new fuel filter and push it onto the end of the fuel line until it is securely attached. Push the new fuel filter into the fuel tank and ensure that the fuel line is resting at the bottom of the tank.

Finally, refill the fuel tank with the appropriate fuel/oil mixture and replace the spark plug wire boot over the top of the spark plug.

You may need to remove the fuel tank to access the filter

The fuel filter on a Stihl weed eater is located inside the fuel tank, at the end of the fuel line. This means that, to access the filter, you will need to remove the fuel tank.

First, set the weed eater on a level surface and disconnect the spark plug boot to prevent accidental start-up. Then, remove the fuel cap by lifting the locking lever to the vertical position and turning the cap counter-clockwise. If the tank still contains fuel, siphon it into a container using a hand siphon.

Now, you can remove the fuel tank. This may require removing some screws. Once the tank is removed, you will be able to access the fuel filter. Pull the end of the fuel line and the fuel filter out of the tank using needle-nose pliers or a hooked piece of wire.

It is worth noting that the fuel line and tank grommet may break upon removal, so it is recommended to have replacements ready. Additionally, ensure that you dispose of any fuel properly.

You can use a screwdriver to fish out the filter

To change the fuel filter on a Stihl weed eater, you'll first need to locate the filter. In some models, the filter is accessible by removing the fuel cap and tilting the engine. However, in most cases, you will need to remove the fuel tank to access the filter.

Now, for the part where you use a screwdriver to fish out the filter:

Firstly, remove the fuel tank by unscrewing the screws holding it in place with a screwdriver. Be careful not to lose any screws and place them aside in a safe place. Once the screws are removed, gently lift and remove the fuel tank.

Now, you'll be able to see the fuel line inside the tank. At the end of this fuel line is the fuel filter. This is where your screwdriver comes in handy. You can use the screwdriver to gently nudge and hook the filter out. If your screwdriver doesn't have a hook, you can create a hook by bending a coat hanger and attaching it to the screwdriver. This makeshift tool can then be used to carefully fish out the filter.

Be cautious not to apply too much force as you don't want to damage any surrounding components or break the fuel line. It's also a good idea to place a cloth or newspaper beneath the engine to catch any fuel that may spill during this process.

Once you've successfully removed the old filter, you can now install a new one. Simply guide the new filter into the fuel line and secure it in place. Reattach the fuel tank by screwing it back into position.

And that's it! You've successfully used a screwdriver to fish out and replace the fuel filter on your Stihl weed eater. Remember to always exercise caution when working with fuel and ensure your work area is well-ventilated.

You can also use a coat hanger to fish out the filter

To change the fuel filter on a Stihl weed eater, you'll need to access the filter by removing the fuel cap and tilting the engine, or by removing the tank and pulling out the grommet that the fuel line passes through.

If you don't want to remove the tank, you can use a long tool to 'fish out' the filter. One way to do this is by bending a coat hanger into a hook shape. You can also cut a small hook into a wire coat hanger with a pair of pliers.

To use the coat hanger method, start by removing the wire and boot from the spark plug. Then, remove the fuel tank cap and pull the retainer free of the tank. Now, you can use your hooked coat hanger to pull the fuel filter out of the gas tank.

Once the filter is out, slide the retaining spring away from the filter using wire cutters or a set of needle-nose pliers. Pull the old filter off the fuel line with a twisting and pulling motion. Now, you can install the new fuel filter by attaching it to the fuel line. Slide the retaining spring towards the filter to secure it, then push the new filter into the tank. Reinsert the fuel cap retainer and refill the fuel tank if necessary. Finally, reattach the wire and boot to the spark plug.

You can use a long pair of hemostats to help with the process

To change the fuel filter on a Stihl weed eater, you'll first need to locate the fuel filter. In some models, the filter may be visible or accessible by removing the fuel cap and tilting the engine. However, in most cases, you will need to remove the fuel tank to access the filter.

Now, here's where a long pair of hemostats comes in handy. As the fuel filter is located at the end of the fuel line inside the tank, you can use the hemostats to "fish out" the fuel line and filter from the tank. This technique helps you avoid the need to remove the tank and reduces the risk of breaking the fuel line and tank grommet during the process.

To do this, carefully insert the hemostats into the tank and grasp the fuel line securely but gently to avoid any damage. Once you have a good grip, slowly pull the fuel line and filter out of the tank. With the filter in hand, you can now replace it with a new one.

When installing the new fuel filter, use the hemostats again to guide the new fuel line into the tank, ensuring it follows the same path as the old line. Gently push the new line into the tank until it reaches the end, being careful not to bend or damage the line. Once the new line is in place, you can secure it by attaching the new filter and ensuring a tight fit.

Using a long pair of hemostats provides the precision and reach needed to access the fuel filter and line without causing unnecessary damage or requiring extensive disassembly of the weed eater. It's a handy tool to have for this maintenance task.
