The Harley Sportster is a motorcycle manufactured by Harley-Davidson. When it comes to the fuel lines of the Sportster, there is some variation in size depending on the model year and type of fuel injection system. For example, the Doss Gas Tank Fuel Line for Fuel Injection for 2007-2022 XL Sportster models has a diameter of 1/4 inch. However, some owners of the Sportster have mentioned that their fuel lines were either 1/4 or 5/16 of an inch in diameter, with 5/16 being more common in aftermarket fuel lines. It is important to note that modifying fuel lines should be done with caution and in accordance with professional advice.

What You'll Learn
Sportster fuel lines are 1/4 or 5/16
The size of a Sportster's fuel line depends on the make and model of the bike, as well as the size of its jets. The stock size for a Sportster fuel line is 1/4", but some people opt for a larger 5/16" fuel line.
A 1/4" fuel line is sufficient for a 6.40mm total jet. However, if your bike has larger jets, you may need to consider a larger fuel line to accommodate the increased fuel flow. In this case, a 5/16" fuel line may be more appropriate.
You can find both 1/4" and 5/16" fuel lines and filters readily available on the aftermarket. It is important to note that a 5/16" fuel line will clamp down on a 1/4" spigot, so it is possible to use a larger-sized line if needed.
When it comes to Sportster fuel lines, there are a few options to consider. One option is the Doss Gas Tank Fuel Line, which is designed for fuel injection in 2007-2022 XL Sportster models. This fuel line has a 1/4" inch ID and comes in a variety of colours, including black, clear, and grey. Another option is the Motion Pro fuel line, which also has a 1/4" inch ID and is available in packs of 10.

5/16 is common in aftermarket parts
When it comes to Sportster fuel lines, the size can vary depending on the specific model and application. However, it is worth noting that 5/16 inch fuel lines are commonly found in aftermarket parts for Sportster motorcycles. This size is larger than the stock fuel line size of 1/4 inch and is often chosen by riders who have bikes with larger jets, as it allows for increased fuel flow to meet the demands of the larger jets.
Aftermarket parts for Sportster motorcycles often offer a range of customization and performance options, and fuel lines are no exception. While the stock fuel line size of 1/4 inch is sufficient for most applications, there are situations where a larger fuel line is beneficial. Riders with bikes that have larger jets, for example, may opt for a 5/16 inch fuel line to ensure adequate fuel delivery. This is because a larger fuel line can provide increased fuel flow, which is necessary when the jets are drawing more fuel.
It is important to note that while a larger fuel line can accommodate higher fuel demands, it is not always necessary. For most riders with stock or mildly modified bikes, the standard 1/4 inch fuel line will be more than adequate. However, for those with significant engine modifications or performance upgrades, a larger fuel line may be required to keep up with the increased fuel demands.
When it comes to installing a 5/16 inch fuel line on a Sportster, it is generally a straightforward process. As mentioned by a rider, the larger line can fit over a 1/4 inch spigot, ensuring a secure connection without any leaks. This flexibility in sizing allows riders to upgrade their fuel lines without having to worry about compatibility issues. However, it is always recommended to double-check the specific requirements of your motorcycle before making any modifications.
In conclusion, while the standard fuel line size for Sportster motorcycles is 1/4 inch, it is common to find 5/16 inch fuel lines in the aftermarket parts market. This larger size caters to riders with modified bikes that require increased fuel flow to match the demands of larger jets or performance upgrades. Ultimately, the decision to stick with the stock fuel line size or upgrade to a larger size depends on the specific needs and modifications of your Sportster motorcycle.

1/4 is standard for stock parts
The standard size for stock parts of Sportster fuel lines is 1/4". This measurement is specific to the internal diameter of the fuel line, which is the most important factor when considering fuel flow. The external diameter of the fuel line is less critical, and often a range of sizes will fit.
While 1/4" is the standard size, some Sportster owners opt for a larger 5/16" fuel line. This is usually done when there is a requirement for increased fuel flow, such as when using larger jets. However, it is important to note that simply increasing the size of the fuel line may not result in a significant increase in fuel flow. The choke point for fuel is often the float valve in the carb, not the hose itself.
For those looking to replace their fuel lines, it is recommended to take the old line off and match it up at an auto parts store. This ensures that the correct size is purchased, as there are a variety of diameters available. It is also worth noting that the size of the fuel line may not be of utmost importance unless the bike is used for drag racing.
In addition to the internal and external diameters, fuel lines also come in a variety of colours, including black, clear, and grey. These different colours offer the same functionality but allow for customization to match the bike's aesthetic.

Larger fuel lines are needed for larger jets
When it comes to fuel systems, it's important to understand the relationship between fuel line sizes and fuel supply restriction. The size of the fuel line can impact the flow of fuel to the engine, and in some cases, using a fuel line that is too small can lead to issues such as fuel starvation.
In general, it's recommended to use larger fuel lines for larger jets or engines. This is because the fuel flow rate is typically higher for larger jets, and a larger fuel line can accommodate this increased flow more effectively. Additionally, longer fuel lines may require more fittings, valves, and manifolds, which can further restrict the fuel flow, making the use of larger fuel lines even more critical.
For example, consider a vessel owner who experienced fuel starvation issues with their Yanmar 6LYA engine. It was discovered that they had used a 1/2" ID fuel line, which was insufficient for their engine's needs. In this case, a larger fuel line would have been necessary to ensure adequate fuel delivery.
Another factor to consider when determining fuel line size is the type of fuel being used. For example, ethanol requires approximately 30% more fuel than gasoline to generate the same HP, while methanol requires twice the amount. As a result, it is recommended to use fuel lines that are one to two sizes larger than the gasoline requirement when designing a fuel line system for these alternative fuels.

Fuel line size doesn't affect fuel flow
The fuel line size does not affect the fuel flow, as long as the pressure loss is accounted for during the planning stage of the fuel delivery system design.
Every fuel line experiences pressure loss, and this loss depends on two factors: the length of the fuel line and the fuel flow rate. The longer the fuel line, the more friction is incurred, and as the rate is increased, so is the friction. This friction reduces the pressure under which the fluid is delivered.
Fuel lines that feed pressure gauges experience the least amount of loss, as the flow rate through the gauge line is very low. Therefore, the size of the fuel line does not affect the fuel flow in this case, as the pressure loss is minimal.
However, it is important to note that the size of the fuel line can affect the pressure drop, especially in carbureted systems. For example, a comparison between -6AN and -8AN supply fuel lines, both 14' long, showed that the -6AN fuel line had a pressure drop of nearly 4 PSID, while the -8AN fuel line had a drop of almost 1.5 PSID. This difference in pressure drop could potentially affect the performance of the fuel system if the pressure loss is not within the tolerable range.
In summary, while the fuel line size does not directly affect the fuel flow, it can impact the pressure drop, which in turn may influence the performance of the fuel system. Therefore, it is crucial to consider the relationship between fuel line size and fuel pressure when designing a fuel delivery system.
