The fuel line inside a snowmobile gas tank is a crucial component, ensuring the smooth flow of fuel from the tank to the engine. However, choosing the right fuel line can be challenging, as some lines degrade quickly, leading to leaks and other issues. This is a common problem faced by snowmobile owners, with many reporting that their fuel lines don't even last a full season before developing issues. The type of fuel used can also impact the performance and longevity of the fuel line, with non-ethanol gas and race fuel being popular choices among snowmobile enthusiasts.

What You'll Learn
The Tygon fuel line is prone to hardening, cracking and leaking
One user reported that their Tygon fuel line did not even last a full season before it started to harden at the fittings, crack and leak. Another user, who had tried both Tygon and BRP fuel lines, found that the Tygon line was more prone to cracking and leaking, while the BRP line turned soft and leaked at bends.
The issue appears to be caused by the fuel itself, with one user speculating that the "new gas" would eat up the vinyl fuel line. This is supported by another user's comment that "most fuel line will be [...] bought anywhere that sells small engine stuff", suggesting that the fuel is a more significant factor in the degradation of fuel lines than the type of line used.
To mitigate this issue, some users have recommended using clamps on the fuel lines for added security, or purchasing fuel lines from a dealer to ensure they are rated for fuel use.

The BRP line turns soft and then leaks
Snowmobiles use fuel lines to transport fuel from the tank to the pump and then to the carb. The fuel line inside the tank should be soft and flexible, but it should not be made of rubber as the fuel will eat away at it, leaving a soft rubbery goo in the bottom of the carbs.
The BRP line is a type of fuel line that can be used inside snowmobile gas tanks. However, the BRP line has been known to turn soft and then leak. This is likely due to the fuel line degrading over time. One user reported that the BRP line turned soft and leaked after just one season of use.
There are a few alternative fuel lines that can be used inside snowmobile gas tanks. One option is the yellow Tygon line, although this has also been known to harden and crack after a full season of use. Another option is the blue Tygon line, which may have similar issues to the yellow Tygon line. A third option is to use a bulk black rubber fuel line, which one user reported lasted for two seasons without any issues. However, this type of fuel line cannot be used inside the tank.
It is important to note that fuel lines should always be rated for fuel use to prevent degradation and leaks.

The black rubber fuel line is not suitable for inside the tank
To avoid this, it is important to use a fuel line that is rated for fuel use. This will ensure that the line is resistant to the corrosive effects of the gas. It is also worth considering the type of gas you are using, as non-ethanol gas may be less likely to cause degradation.
There are a variety of fuel lines available on the market, including the Tygon fuel line and the BRP fuel line. However, some people have reported issues with these lines as well, with the Tygon line cracking and leaking, and the BRP line turning soft and then leaking.
One option to consider is the OEM fuel line from your dealer. This line is designed specifically for your snowmobile and may be more durable than other options. It is also worth shopping local and supporting your dealer when you need a more specific part.

The Fast Flow Fuel Line is made for race fuel
When selecting a fuel line for a snowmobile, it is important to consider the type of fuel being used. Non-ethanol gas, for example, can cause issues with certain fuel lines, leading to hardening, cracking, and leaks. It is also important to ensure that the fuel line is rated for fuel use, as gas can eat away at lines that are not designed for fuel, resulting in a soft, rubbery goo in the bottom of the carbs.
There are various options available for fuel lines, including the Tygon fuel line, the BRP fuel line, and plain black bulk rubber fuel lines. However, these options may not always be suitable for inside the tank. For instance, the BRP line has been known to turn soft and leak when used inside the tank.
To avoid issues with fuel line degradation, it is recommended to consider the type of fuel being used and select a fuel line that is rated for fuel use. The Fast Flow Fuel Line is a reliable option for race fuel, offering durability and performance for snowmobile enthusiasts.

The OEM fuel line is recommended for its durability
One user reported that they replaced their fuel line with the OEM stuff and found it to be a good investment, as it was soft and flexible, and didn't cost much. They also emphasised the importance of supporting local dealers, who can provide expert advice and specialised parts for your snowmobile.
Another important consideration when choosing a fuel line is its rating for fuel use. If a fuel line is not rated for fuel, the gas can eat away at it, leaving a soft, rubbery residue in the bottom of your carbs. This can cause performance issues and even damage your snowmobile. Therefore, it is crucial to select a fuel line that is specifically designed for fuel applications and compatible with the type of fuel you are using.
Additionally, it is worth noting that the durability of a fuel line can also depend on the type of fuel you are using. Some fuels, such as E85, may be more aggressive and cause faster degradation of the fuel line. In such cases, it is even more important to choose a durable and compatible fuel line, like the OEM option, to ensure the longevity of your snowmobile's fuel system.
