Nitro RC fuel is a blend of nitromethane and methanol, with some portion of the mixture being oil. The ideal length of a nitro RC fuel line is a topic of debate among enthusiasts, with some preferring longer lines and others opting for shorter ones. The length of the fuel line can impact the performance and tuning of the RC vehicle, with some suggesting that a longer line can help smooth out pulses from the tank and provide a more steady pressure, resulting in a more even flow of fuel. However, others argue that the length of the fuel line has no impact on power or speed. Ultimately, the perfect fuel line length may depend on the specific vehicle and engine setup, with some experimentation and trial and error required to find the optimal length.

The ideal length for a nitro RC fuel line is between 6 and 12 inches
Nitro RC fuel is a blend of nitromethane and methanol. It is used in RC vehicles and contains 10-40% nitromethane, with the rest being methanol. The ideal length for a nitro RC fuel line is between 6 and 12 inches. This length ensures that the fuel line has enough fuel to keep the engine running and provides a steady pressure for the carburetor.
Some people prefer longer fuel lines as it gives them more time to get to their vehicle if it flips over before the fuel in the line runs out. Longer lines can also help with tuning by providing a more constant pressure and smoother pulses. However, longer fuel lines are not always better. Very long lines can cause problems with pressure and volume, and can make it difficult to tune the engine.
On the other hand, very short fuel lines can also cause issues. A pressure line needs to be at least 6 inches to maintain constant pressure. If it is too short, it will pulse with every exhaust stroke.
The ideal length for a nitro RC fuel line is, therefore, a balance between these two extremes. A fuel line that is too long or too short can cause problems with engine performance and pressure. Keeping the fuel line between 6 and 12 inches will ensure optimal performance and prevent any issues with fuel delivery.
It is important to note that the length of the fuel line is not related to power or speed, as some may believe. The perfect length for a nitro RC fuel line depends on the specific vehicle and engine setup, and it may take some trial and error to find the ideal length for your RC vehicle.

A longer fuel line is said to help with tuning and keeping the engine running when flipped over
While there is no consensus on the ideal length for a nitro RC fuel line, some enthusiasts claim that longer fuel lines are beneficial for tuning and keeping the engine running when flipped over.
A longer fuel line is said to help with tuning by providing a more consistent pressure and fuel flow to the carburettor. This is because the longer line can smooth out pulses from the tank, resulting in a steadier pressure and a more even flow of fuel. This can lead to more consistent engine performance and improved lap times on the same track.
Additionally, a longer fuel line can help keep the engine running when the vehicle is flipped over. If the fuel level is low, a longer line can prevent the fuel pickup from being exposed, allowing the engine to continue running until the fuel in the line runs out. This provides extra time for the driver to reach the vehicle and flip it back over.
However, it is important to note that there are also potential drawbacks to longer fuel lines. Firstly, if the line is too long, there may not be enough pressure from the exhaust to push the fuel, causing the engine to run lean or not at all due to fuel starvation. Secondly, longer fuel lines can be more difficult to tune, especially if they are significantly longer than the recommended length of 6 to 8 inches.
Ultimately, the optimal length for a nitro RC fuel line may depend on various factors, including the specific engine and vehicle setup. Some enthusiasts recommend starting with a longer line and gradually shortening it until the desired tuning and performance are achieved.

A short fuel line may cause problems with constant pressure
Nitro RC fuel contains some portion (between 10% and 40%) of nitromethane mixed with methanol. The methanol is the combustible component in the fuel. The simple hydrocarbon burns in the presence of oxygen and releases energy that drives the RC vehicle.
The length of the fuel line in an RC vehicle is important for maintaining constant pressure and optimal performance. A short fuel line may cause problems with constant pressure, as it can result in pulsing with every exhaust stroke instead of maintaining a steady pressure. A longer fuel line helps to smooth out these pulses and provides a more even flow of fuel to the carburetor.
The ideal length for a fuel line is generally considered to be around 6-8 inches for both the pressure and fuel lines. However, some sources suggest that a longer fuel line, up to 10-12 inches, may be beneficial. Ultimately, the optimal length may depend on the specific RC vehicle and its engine configuration.
It's worth noting that having a longer fuel line can also be advantageous if the RC vehicle flips over. With a longer line, the vehicle can continue to run until the fuel in the line runs out, providing more time to get to the vehicle before it dies. However, some users prefer to run the shortest length of fuel line possible, as this can make it easier to manage and fit the line within the vehicle.
To find the optimal fuel line length for your RC vehicle, it may involve some trial and error, as well as referring to the RC manual for specific recommendations.

The length of the fuel line is not related to power or speed
The length of a fuel line for an RC vehicle is not related to power or speed. There is no magic formula for the length of tubing on a fuel feed. The length of the tubing on the fuel feed includes the length of the fuel filter. The length can vary from 6 to 12 inches. Some RC enthusiasts prefer to run as long a fuel line as possible on their nitros so that if the vehicle flips upside down, it will run until the fuel in the line runs out. This gives them more time to get to the vehicle before it dies.
However, some people prefer to run the shortest length of fuel line possible. They argue that the "theory" about longer fuel lines making more horsepower is false. The optimum length of the fuel line depends on the RC vehicle's engine and the type of RC. The pressure line should be at least 6 inches to maintain constant pressure, rather than pulsing with every exhaust stroke.
The length of the fuel line is also important for the tuning of the RC vehicle. A longer line can help to smooth out pulses from the tank and provide a more steady pressure, resulting in a more even flow of fuel to the carburetor. The perfect length of the fuel line is generally considered to be "not too long, not too short".
The blend of the fuel is also important for the performance of the RC vehicle. Nitro fuels contain 10-40% nitromethane mixed with methanol. The methanol is the combustible component in the fuel. The nitromethane does not add any combustion properties but plays an important role in keeping the engine healthy. The ideal concentration of nitromethane depends on the desired output of the engine. For racing RC cars, the concentration should be less than 12%, while for longer engine life, it should be around 20%.

Nitro RC fuel contains nitromethane, methanol, and oil
Nitro RC fuel is a fuel used to power the thermal engine of RC vehicles. It is made from three main elements: nitromethane, methanol, and oil. The nitromethane provides oxygen, the methanol generates combustion, and the oil lubricates the engine and keeps it cool.
Nitromethane is a toxic and flammable substance that requires special precautions when handling it. It is important to wear gloves and eye protection when filling the fuel tank of an RC vehicle with nitro fuel. The fuel should be stored in a sealed, dry environment, away from open flames, to prevent fires and explosions.
The percentage of nitromethane in nitro fuel typically ranges from 10% to 40%, with 20% being a common amount. The higher the percentage of nitromethane, the more power and speed the fuel provides. However, this is at the expense of the engine, which receives less lubrication. For this reason, outside of competition, it is recommended to use fuels with lower percentages of nitromethane, such as 10% or 15%.
The type of oil used in nitro fuel can be castor oil, synthetic oil, or a mixture of both. Castor oil creates a lubricating film when it breaks down at high temperatures, but this can be somewhat messy. Synthetic oil, on the other hand, is less messy but may not provide the same level of lubrication as castor oil. The percentage of oil in nitro fuel typically ranges from 8% to 25%, with 15%-20% being the most common amount. The percentage of oil chosen may depend on the intended use of the RC vehicle. For example, an RC aircraft that runs at wide-open throttle for most of its run may require a higher percentage of oil than an RC car that only runs at full throttle for short spurts.
The length of the fuel line in an RC vehicle can also affect its performance. Some sources recommend keeping the fuel line short, preferably under 6 inches, to prevent leaks and tears. However, others suggest that a longer fuel line can help prevent the engine from stalling when the vehicle is flipped. A longer line can also equalize pressure rhythms from the exhaust, resulting in better acceleration out of corners. Ultimately, there is no one-size-fits-all answer, and the optimal fuel line length may depend on the specific vehicle and its engine configuration.
