Replacing The Stihl Ms361 Fuel Tank: Step-By-Step Guide

If you're looking to change the fuel tank on your Stihl MS361, you may have noticed that the saw is running erratically, as if it's starving for fuel. This could be due to a clogged tank vent, which can occur if the tank vent cover falls off, or there could be a hairline crack in the tank. To access the tank vent, you'll need to remove the handle first, then pull the cap up. You can then take the vent apart and check the filter inside. If you're replacing the tank, you can consider aftermarket options, which are more cost-effective than OEM parts. However, be cautious of cheap Chinese eBay vendors, as the quality may not be up to par.

Aftermarket fuel tanks and covers

When it comes to aftermarket fuel tanks and covers for the Stihl MS361, there are a few options and considerations to keep in mind. Firstly, it is important to assess the quality of the aftermarket parts, as the quality can vary significantly among different vendors and suppliers.

Some recommended vendors for aftermarket fuel tanks and covers include Huztl, Farmertec, and HL Supply. These vendors have received positive reviews from users for their product quality and cost-effectiveness. For example, a user reported having "zero issues" with Huztl fuel tanks for the MS660 and MS361. Farmertec is also mentioned as a reliable source for aftermarket Stihl MS361 parts.

When purchasing aftermarket fuel tanks and covers, it is essential to consider compatibility and potential interference issues with other components, such as the master control lever and the fuel cap. Users have reported that the fuel caps from Definitive Dave work great and can help prevent leakage.

Additionally, it is worth noting that while aftermarket parts can be more affordable, original equipment manufacturer (OEM) parts from authorised Stihl dealers might offer better quality and longevity, although they may come at a higher cost.

When replacing the fuel tank, it is also recommended to consider other related parts, such as the fuel line, bearings, rubber intake manifold, and AV components, to ensure optimal performance and longevity of the chainsaw.

Overall, when choosing aftermarket fuel tanks and covers for the Stihl MS361, it is important to prioritise quality, compatibility, and reliability to ensure a safe and efficient chainsaw operation.

OEM vs. non-OEM parts

When it comes to replacing the fuel tank on your Stihl MS361 chainsaw, you may be considering whether to opt for original equipment manufacturer (OEM) parts or non-OEM aftermarket alternatives. While both options have their advantages and disadvantages, understanding the key differences between them can help you make an informed decision.

OEM parts are designed and manufactured by the original equipment manufacturer, in this case, Stihl. These parts are made to meet the exact specifications of your MS361 model, ensuring a perfect fit and optimal performance. OEM parts are generally known for their high quality and durability, and using them can help maintain the value of your chainsaw. However, they tend to be more expensive than non-OEM parts, and you may need to purchase them directly from Stihl or authorised dealers.

On the other hand, non-OEM aftermarket parts are produced by third-party manufacturers and are often more affordable. While some non-OEM parts may be of good quality and fit your MS361 without issues, others may be inferior and not last as long as their OEM counterparts. It's important to carefully research the reputation of the aftermarket manufacturer and read reviews from other buyers to ensure you're getting a reliable product. Additionally, using non-OEM parts may decrease the resale value of your chainsaw, as prospective buyers may view it less favourably.

When it comes to fuel tanks, you can find both OEM and non-OEM options available. For example, you can purchase a non-OEM gas fuel tank and rear handle assembly for the MS361 online. On the other hand, if you prefer to go with OEM parts, you can source them from authorised Stihl dealers, although they may be more expensive.

Ultimately, the decision between OEM and non-OEM parts depends on your specific needs and budget. If you're looking for guaranteed quality, performance, and longevity, OEM parts are the way to go. However, if you're comfortable taking on a little more risk and don't mind the possibility of having to replace parts more frequently, non-OEM alternatives can offer significant cost savings.

Tank vent issues

The Stihl MS-361 is a powerful chainsaw, but fuel tank vent issues can cause problems with its performance. If your MS-361 is running erratically, like it's starving for fuel, the tank vent may be clogged or plugged.

The tank vent on the Stihl MS-361 is located under a small square cap on the right side, partly under the front handle. You don't need to remove the handlebar to access it, but you may need to take off the handle first. Once you've located the vent, you can try cleaning or replacing it. If you decide to clean it, you can take it apart and remove the filter inside. If that doesn't work, a new tank vent is an inexpensive fix, usually costing around $6.

If you want to test whether the vent is the issue, you can use a vacuum tester. Apply suction to the fuel line, and if the vent is functioning correctly, it should not be able to build a vacuum. The vent is designed as a one-way valve and will only vent when suction is applied.

Another workaround for this issue is to immediately crack open the fuel cap after running the saw for a long session. This lets air into the tank and relieves any low-pressure condition that may be preventing fuel from being pulled into the carburetor.

Remember to always exercise caution when working with power tools and equipment, and if you're unsure about any procedures, consult a professional.

Fuel cap recommendations

When it comes to fuel cap recommendations for the Stihl MS361, there are a few options to consider. Firstly, it is important to ensure that any fuel cap you purchase is compatible with the MS361 model.

One option is to purchase an OEM (Original Equipment Manufacturer) fuel cap from Stihl or an authorised dealer. These caps are designed specifically for the MS361 and should fit perfectly. They may be more expensive than aftermarket options, but they offer the assurance of quality and compatibility.

Aftermarket fuel caps are also available from various sellers, including online retailers like Amazon and eBay. Some recommended brands include Definitive Dave, whose fuel caps are reported to work great and are cost-effective. Another brand to consider is Huztl, which has been mentioned by users as being good quality and compatible with the MS361.

When purchasing an aftermarket fuel cap, it is important to read reviews and ensure that the cap is designed for the MS361 or is compatible with the specific model. It is also worth considering the quality of the materials used, as some aftermarket caps may be more prone to leaking or distortion over time.

Additionally, when replacing the fuel cap, it is recommended to also replace the fuel line to ensure a tight seal and prevent any leaks.

Finally, it is worth mentioning that STIHL has issued a recall for certain toolless fuel caps due to safety concerns. This recall affects specific products with toolless fuel caps sold before a certain date. If your MS361 is affected by this recall, you should discontinue use and contact an authorised STIHL dealer to have a new toolless fuel cap installed free of charge.

Fuel line recommendations

When replacing the fuel tank on your Stihl MS361, it is important to consider the fuel line and ensure it is in good condition. The fuel line is responsible for delivering fuel from the tank to the carburettor, and a damaged or clogged fuel line can cause performance issues or even engine damage. Here are some recommendations to consider when it comes to the fuel line:

• Replacement Fuel Line Hose: It is recommended to replace the fuel line when installing a new fuel tank. This will ensure optimal performance and reduce the risk of future issues. Replacement fuel line hoses designed for the Stihl MS361 are readily available from various sellers.
• Fuel Line Condition: Inspect the fuel line for any signs of deterioration or damage. Fuel lines are prone to deterioration, especially where they flex the most between the carburettor and fuel tank. High ethanol content in the fuel can also contribute to fuel line degradation over time.
• Fuel Line Compatibility: Ensure that the replacement fuel line is compatible with the Stihl MS361. The correct fuel line will have the part number 1128 358 7701 or 11283587701.
• Fuel Filter: Consider installing a new fuel filter along with the fuel line. The fuel filter helps to prevent debris and contaminants from entering the carburettor and engine, and it is important to keep it in good condition.
• Fuel Line Maintenance: Regularly inspect and maintain the fuel line to prevent future issues. Keep a couple of replacement fuel lines on hand, especially if you use your chainsaw frequently or store it for extended periods.
• Aftermarket Options: If you are considering an aftermarket fuel tank, pay close attention to the fuel line and any necessary adjustments. Some aftermarket tanks may require additional modifications or different fuel lines to ensure a proper fit and function.
