The Stihl 026 fuel line is a common component that needs replacing. There are two types of fuel line: the straight one and the S-shaped one. The S-shaped one is the preferred option, as the straight one is difficult to install and can cause issues with the fuel pickup.
| Characteristics | Values |
|---|---|
| Shape | S-shaped |
| Filter replacement | Easier with S-shaped line |

What You'll Learn

Using the fuel line from an 036
The Stihl 026 fuel line can be replaced with the fuel line from an 036. The 036 fuel line fits the old smaller diameter hole in the tank and is longer for easier filter replacement. However, it is harder to replace filters with the straight hose. When the straight hose eventually shrinks, it will leave the fuel pickup off the bottom of the tank.
The Stihl 026 fuel line replacement can be purchased from a Stihl dealer. The part is extremely hard to get seated in, and it is recommended to enlarge the opening to the tank for the new hose.
The straight hose is not the best option, as it is difficult to get the filter installed. It is recommended to use a guide wire and install it from the tank outward with the filter already attached.
The 036 fuel line is also compatible with the Stihl 034, 038, and 036 Pro chainsaws. It is important to verify that this is the correct part needed for your model before purchasing, as some models listed used more than one style/part number, depending on the manufacture date.

Enlarging the opening to the tank for the new hose
To replace the Stihl 026 fuel line, you will need to enlarge the opening to the tank for the new hose. This is because the new hose is larger in diameter than the old one.
One way to do this is to drill out the old hole, making it larger and allowing the new hose to fit. This will also make it easier to replace the filter in the future.
It is important to note that the straight hose is harder to work with and may not be the best option. The S-shaped hose is recommended by some users as it is easier to install and doesn't have the same issues with filter replacement.
When enlarging the opening to the tank, it is crucial to be careful and precise to avoid damaging any other components or creating leaks. It is also important to use the correct tools and follow safety precautions when working with power tools and fuel systems.

Using the S-shaped hose
The S-shaped hose is the best option for replacing the fuel line on a Stihl 026. The straight hose is harder to replace filters with and can leave the fuel pickup off the bottom of the tank when it shrinks. The S-shaped hose is also longer, which makes it easier to replace the filter.
To replace the fuel line, you will need to enlarge the opening to the tank for the new hose. This can be done by drilling out the hole. It is important to buy the correct fuel line for your Stihl 026, as aftermarket parts may not fit properly.
When installing the S-shaped hose, it is recommended to install it from the tank outward with the filter already attached. This will ensure that the hose is seated properly and will not tear. It is also important to note that some jugs have an intake snout "lip", which can cause fuel to puddle and eventually stall the saw at idle or upon hitting the throttle after prolonged idle.
Overall, the S-shaped hose is the preferred option for replacing the fuel line on a Stihl 026 due to its ease of installation and longer length, which makes filter replacement easier.

Using a guide wire to install the straight hose
I found some information about replacing the fuel line on a Stihl 026 chainsaw.
> With the straight one, I add a guide wire to it, and install it from the tank outward with the filter already attached. Just drill the tank and use the correct line.
Here's a step-by-step guide on how to do this:
- Drill the tank to enlarge the opening for the new hose.
- Attach the filter to the new straight hose.
- Feed the guide wire through the tank opening.
- Attach the hose to the guide wire and pull it through the tank opening.
- Ensure the hose is seated correctly and securely.
Some users have reported that the straight hose is harder to work with than the S-shaped one, and that it can be difficult to get the filter installed. It's also important to note that the straight hose may shrink over time, causing the fuel pickup to be left off the bottom of the tank.
There are also a number of products available to assist with tree cutting and trimming, including throw line kits and safety harnesses.

Vac testing the saw
To replace the fuel line on a Stihl 026, you may need to enlarge the opening to the tank for the new hose. Some people have suggested using the fuel line from an 036, as it fits the old smaller diameter hole in the tank and is longer for easier filter replacement. However, the straight hose can be difficult to work with, and when it shrinks, it will leave the fuel pickup off the bottom of the tank.
To avoid this issue, it is recommended to use the S-shaped fuel line. This can be installed by drilling the tank and using the correct line. Additionally, it is important to note that some jugs have an intake snout "lip", which can cause fuel to puddle and lead to stalling. To test for this issue, you can perform a Vac test on the saw.
- Disconnect the fuel line from the carburettor and plug the end to prevent any fuel leakage.
- Start the saw and let it run for a few minutes to build up a vacuum in the fuel system.
- Release the throttle and observe the fuel level in the carburettor. If the fuel level drops, it indicates a vacuum leak in the system.
- Inspect the fuel lines, connections, and carburettor for any signs of damage or wear that could be causing the leak.
- If no issues are found, repeat the test to confirm the results.
- If a vacuum leak is detected, repair or replace the affected components as necessary.
By performing a Vac test, you can identify and address any vacuum leaks in the fuel system, ensuring proper fuel delivery and preventing stalling issues. It is important to follow the recommended procedures and safety precautions when working with power equipment to ensure your safety and the proper functioning of the saw.
