Key Takeaways
- Damaged fuel tanks, broken gas lines, and carburetor issues are common causes of gas leaks in string trimmers.
- Inspecting the fuel tank for cracks or damage can help identify the source of a gas leak.
- Checking the gas lines for leaks or blockages is crucial in preventing fuel from seeping out of the trimmer.
- Cleaning or rebuilding the carburetor may be necessary to fix leakage caused by clogs or damaged components.
Why Is My String Trimmer Leaking Gas?
There are a few common reasons why your string trimmer may be leaking gas, including a damaged fuel tank, broken gas lines, or issues with the carburetor.
Damaged fuel tank
A damaged fuel tank on your PowerSmart 25.cc string trimmer is a common culprit when it comes to gas leaks. Overfilling the tank can induce pressure, causing cracks and subsequent leakage.
But that’s not the only reason a fuel tank may leak. Often times, it might be an issue with the gas cap itself. Vibration from operation can fatigue this component over time, leading to hairline fissures which become perfect escape routes for your expensive fuel while also allowing unwanted contaminants into the mix.
Furthermore, certain models have grommets between the fuel lines and gas tanks – prolonged exposure to gasoline can cause these grommets to deteriorate and fail to seal properly, resulting in more leaks you’d wish weren’t there.
Broken gas lines
Broken gas lines can often be the culprit behind a leaking string trimmer. Due to prolonged use, these lines that carry fuel from the tank to the carburetor might become brittle or damaged.
If you’re noticing your Weedeater consistently seeping out gas, there’s a high chance it could be due to a cracked line. This issue is particularly common in older models where wear and tear significantly impact the lifespan of these components.
Fixing this problem isn’t as daunting as it sounds. With careful examination, locate any signs of breakage or brittleness along your string trimmer’s fuel lines. Any damaged sections will need prompt replacement to prevent further leakage and potential damage to other parts of your tool such as the Ryobi S430 gas cap or even more specifically targeted tools like BG Stihl 86 blower which are known for experiencing similar fuel leakages issues due their design structure.
Remember, maintaining healthy functioning gas lines is not just about preventing leaks but also ensuring your machine operates at peak performance with minimal interruptions.
Carburetor issues
In my experience as a lawn care expert, carburetor issues often surface as the underlying culprit for your string trimmer leaking gas. It’s crucial to note that your string trimmer’s carburetor can get clogged with old fuel residue–an issue leading directly to leakage.
As gasoline inside the machine ages and deteriorates, it can harm various parts of the system, particularly affecting diaphragms in the carburetor that may cause gas leaks when they wear out.
Difficulty starting your machine? Carburetor complications could be causing this too! Rebuilding or replacing your faulty carburetor helps curb persistent leakage and gets your trusty Weedeater back in top-notch shape.
Also noteworthy is ensuring we promptly replace our tool’s fuel every thirty days to prevent such setbacks because prevention always works best!
How to Identify and Fix String Trimmer Gas Leaks
To identify and fix gas leaks in your string trimmer, start by inspecting the fuel tank for any cracks or damage. Next, check the gas lines for leaks or blockages that may be causing the fuel to leak.
If necessary, clean or rebuild the carburetor to ensure it is functioning properly and not contributing to the leakage issue. Remember to replace any old or weathered fuel lines immediately, tighten loose clamps, and address any other potential causes such as a rich running engine or air filter problems.

Inspect fuel tank for cracks or damage
To address a gas leak in your string trimmer, the first step is to inspect the fuel tank for any cracks or damage. Over time, the constant exposure to vibrations and outdoor conditions can cause stress cracks around the anchor nuts of the fuel tank.
These cracks may not be easily visible at first glance, so it’s important to carefully examine all areas of the tank. Keep an eye out for any signs of discoloration, bulges, or deformities as well.
By identifying these issues early on, you can prevent potential gas leaks and ensure that your trimmer operates safely and efficiently.
Check gas lines for leaks or blockages
Inspecting the gas lines is an essential step in identifying and fixing gas leaks in your string trimmer. Start by moving your trimmer to a well-ventilated area and carefully examine the fuel lines for any signs of cracks or damage.
If you spot any, it’s crucial to replace them promptly to prevent further leaks. Additionally, check for blockages in the fuel lines that could be causing restricted fuel flow. Clearing these blockages will ensure that your trimmer gets a steady supply of fuel, improving its performance and preventing potential leaks down the line.
By regularly checking and maintaining your gas lines, you’ll keep your string trimmer running smoothly and efficiently.
Clean or rebuild the carburetor if necessary
If you find your string trimmer leaking gas, it might be due to issues with the carburetor. The carburetor is responsible for mixing air and fuel in the right proportions for combustion.
Over time, it can become clogged or damaged, leading to fuel leaks. To fix this problem, you will need to clean or rebuild the carburetor if necessary. This involves removing the carburetor from the trimmer, disassembling it, and cleaning all its components thoroughly with a carburetor cleaner.
If there are any worn-out or broken parts, they should be replaced during the rebuilding process. By addressing carburetor issues promptly, you can ensure that your trimmer operates smoothly without any gas leaks impacting its performance.

FAQs
1. Why is fuel coming out of my carburetor?
One common reason for fuel to come out of a carburetor is a cracked fuel line. Over time, these lines can become brittle and develop small leaks, causing fuel to escape. Additionally, if the float valve in the carburetor is not functioning properly, it can allow an excess amount of fuel into the chamber, leading to leakage.
Another potential cause could be a stuck or damaged needle valve that fails to regulate fuel flow correctly.
To fix this issue, start by inspecting the carburetor for any visible signs of damage or wear. If you notice any cracks or breaks in the lines or fittings, they will need to be replaced.
Cleaning the carburetor thoroughly and ensuring all components are working correctly can also help resolve this problem.
Remember that safety should always be a priority when troubleshooting fuel leaks. Avoid working near open flames or sparks and ensure proper ventilation when handling gasoline. If you’re unsure about how to address this issue yourself, it’s best to seek professional assistance or reach out to your trimmer’s manufacturer for guidance.
2. Why is petrol coming out of my strimmer exhaust?
Petrol coming out of your strimmer exhaust can be a sign of a problem in the fuel system. One potential cause is a malfunctioning carburetor float, which allows too much fuel into the carburetor and results in petrol being expelled through the exhaust.
Another possibility is a clogged spark arrester, creating back pressure that forces fuel out through the exhaust. It’s important to identify the exact source of the leak by inspecting components such as the fuel tank, gas lines, and carburetor for damage or blockages.
Regular maintenance and addressing issues promptly can help prevent petrol leakage from becoming a safety hazard.
