Fuel line size for older Arctic Cat models
The fuel line size for older Arctic Cat models depends on the specific model and variant in question. For example, the fuel line size for an Arctic Cat 454 is 3/16 inches, although some users have suggested that 1/4 inch fuel lines can also be used.
Arctic Cat has produced a wide range of snowmobiles, all-terrain vehicles (ATVs), and side-by-side utility vehicles (UTVs) since 1960. The company's first snowmobile was produced in 1960, and they began manufacturing ATVs in 1996 and side-by-side UTVs in 2005. Over the years, Arctic Cat has offered various models with different engine sizes and configurations, including:
- Snowmobiles: The ZR series (440, 500, 580, 600, 700, 800, and 900), FireCat (F-Series), and SaberCat.
- ATVs: Alterra 600 TRV, Alterra 600, Alterra 450, Alterra 300, Alterra 90, Wildcat XX, Prowler Pro, and Prowler Pro Crew.
- UTVs: Prowler, Wildcat, and variations of these models under the Textron Off Road brand name.
It is important to note that the fuel line size may vary even within the same model, depending on the specific engine configuration and other factors. Therefore, it is always recommended to consult the official Arctic Cat resources or a qualified mechanic for the most accurate and up-to-date information regarding fuel line sizes for older Arctic Cat models.

Fuel line size for newer Arctic Cat models
The fuel line size for an Arctic Cat depends on the model. For example, the fuel line size for the 1998 zr440 sno pro model is either 3/16", 1/4", or 5/16". The brake line diameter for a car is not 3/16". The factory size for this model is 3/16", and you could also go for 1/4". The Tygon in yellow is the softest, followed by blue polly. There is also a clear Tygon option, but its performance hasn't been tested yet.
For newer models, like the 2014 800 rr, the hoses are made of a newer material and are gray. For lines that are constantly submerged in gas, you need a special type of line. It is recommended to either buy them from the dealer or buy lines made especially for constant immersion in fuel.
It is also important to note that not all clear hoses are rated for fuel. They will be blue or yellow-orange. If you have throttle bodies, you will need a fuel line rated for the pressure. The blue or yellow-orange lines will not be rated for what you need and will swell much faster because they are not reinforced. A fuel line that is swollen is much more prone to bursting.

Fuel line colour and material
Fuel lines are called hoses or pipes and are used to transfer fuel from one point to another or from a storage tank to a vehicle. The fuel line is usually made of reinforced rubber to prevent breaking and kinking. They are also made of plastic materials, and although they are located in the vehicle’s undercarriage, they cannot be damaged due to the engine moving.
In older models, the fuel line hoses were equipped with copper material. Copper hoses are easy to fit and repair, but they are bulky and expensive compared to other materials. Copper should not be used to replace steel pipes as it cannot handle normal vehicle vibrations and reacts chemically with gasoline.
Modern types of vehicles typically employ fuel lines that are made of plastic, usually nylon. Plastic fuel lines do not rust and are lighter than metal tubing, but they melt at low temperatures and cannot be easily repaired.
Metal fuel lines are made from materials such as steel or aluminum, while rubber fuel lines are made from rubber or other elastomeric materials. Braided fuel lines are typically made from a metal or synthetic fiber braid that is wrapped around a rubber or other elastomeric core. PTFE-lined fuel lines have an inner layer of PTFE (polytetrafluoroethylene), a synthetic fluoropolymer, which is coated with a layer of braided stainless steel or other metal.
The colour of the fuel line depends on the manufacturer and the type of vehicle. For example, the fuel lines for an Arctic Cat 454 are available in different colours such as yellow, blue, red, and clear.

Fuel line replacement method
Fuel lines are essential components of a vehicle's fuel system, and their integrity is crucial for safety and performance. The National Highway Traffic Safety Administration has set stringent standards for fuel system integrity, requiring vehicles not to leak more than 1 oz of fuel during impact and not exceeding 5 oz of fuel five minutes after coming to rest.
There are several options for replacing fuel lines in an Arctic Cat 454, each with its advantages and disadvantages:
Option 1: Replace with a Pre-Bent Line
This option involves replacing the entire fuel line with a pre-bent line sourced from aftermarket or new car dealer channels. While this option can be expensive and labour-intensive, it offers a long-lasting repair, returning the vehicle to like-new condition. It also prevents future leaks and is the preferred method to ensure customer satisfaction. However, it is important to note that this option may not be available for all vehicles.
Option 2: Bend Your Own Lines
If you choose this option, you will need to invest in bending and flaring tools, specifically those that can create quick disconnect fittings. Although the initial investment in the tools can be high, it can pay off in the long run by increasing productivity and reducing waiting times for parts. You will also need to carry a basic assortment of fittings to utilise this method effectively.
Option 3: Nylon Tubing
Nylon tubing and specific fittings can be used as a replacement for metal fuel lines. This option offers flexibility, as the nylon tubing can be used for the entire length of the fuel line or just a section. Nylon tubing is a cost-effective and time-efficient solution when pre-bent lines are unavailable. With the correct fittings, factory-style quick-disconnect fittings can be joined with metal lines or used to replace leaking sections. However, it is important to note that corrosion elsewhere in the system may cause future leaks.
Additionally, it is crucial to understand the underlying causes of fuel line failure to prevent recurrence. The primary reason for metal fuel line failure is corrosion, often initiated when abrasive materials remove the paint or coating on the line, typically at mounting brackets or from debris kicked up from tires.

Fuel line size for other vehicles
The fuel line size for an Arctic Cat 454 is either 3/16 or 1/4.
When it comes to other vehicles, the fuel line diameter is a critical aspect of the fuel system. A larger diameter is generally preferable, but selecting the appropriate diameter is essential. If the diameter is too narrow, your horsepower goal may be compromised. Conversely, if the diameter is too large, the lines will take longer to pressurize, potentially leading to engine damage if the pump struggles to maintain pressure.
In-line fuel pump manufacturers often recommend a fuel line diameter that complements their pumps to prevent starving the pump. Additionally, different fuels have distinct requirements. Ethanol, for instance, demands approximately 30% more fuel than gasoline to generate the same horsepower, while methanol requires twice the amount of fuel.
When designing a fuel line system for ethanol or methanol, it is advisable to opt for one or two sizes larger than the gasoline requirement. Return lines, which are the fuel lines after the regulator, can typically be one size smaller than the feed line.
The most common fittings for competition cars and high-performance vehicles are JIC/AN fittings. These fittings are sized based on a combination of thread size and hose size. Common hose sizes include 6mm, 8mm, 10mm, 12mm, 15mm, and 19mm internal diameters. The hose can be secured with hose clips or swaged on and is offered in low-pressure and high-pressure variants.
Standard sizes for fuel systems are typically 1/8", 1/4", 3/8", and occasionally 1/2". These sizes correspond to measurements of around 10mm, 13mm, 17mm, and 21mm, respectively.
