The Mitsubishi Lancer Evolution, or Evo, is a high-performance car that requires a lot of fuel to run smoothly. The size of the fuel line is an important consideration for Evo owners, as the stock fuel lines can corrode over time, leading to lower fuel pressure. The feed hardline is 5/16, while the return hardline is 1/4. Owners have also reported that the car's feed itself is -6an. Some have chosen to replace their fuel lines with stainless steel or Kevlar options.

The stock fuel line size for the Mitsubishi Lancer Evolution is \-6an
The stock fuel line size for the Mitsubishi Lancer Evolution is -6AN. This information can be hard to come by, but some forums provide detailed discussions on the topic. The fuel line size for the Mitsubishi Lancer Evolution is a common query, and it's important to get it right to ensure a smooth-running engine.
The Mitsubishi Lancer Evolution, also known as the EVO, is a high-performance car that requires a lot of fuel to be pushed through the lines. Over time, the stock fuel lines can corrode and the filters can become clogged, leading to lower fuel pressure. This can cause issues with the car's performance, so it's important to replace the fuel lines and filters as part of regular maintenance or when upgrading to a more powerful engine.
Some EVO owners have reported issues with their fuel systems, including leaking and cracking of the fuel lines. This can occur after about five years of use. To address these issues, some EVO owners have opted to install a double pumper system, which includes two fuel pumps that work together to supply fuel to the engine. This system has been shown to increase the car's horsepower and improve performance.
When it comes to the size of the fuel line, it's important to note that the EVO's feed line is -6AN, while the return line is typically 1/4 or 5/16. Some owners have opted to run a custom -6 feed line from the tank, using the factory feed line as the return. This setup can be ideal as it doesn't require additional adapters or lines, and the necessary adapters can be purchased from specialist retailers.

The OEM factory fitting threads into a metric 14mm x 1.5 thread
The fuel line size for an Evo varies depending on the model and the specific fuel line you're referring to. For example, the feed hard line for the Evo 10 is 5/16", while the return hard line is 1/4". The fuel rail inlet and return fittings also differ.
If you are specifically referring to the OEM factory fitting, it threads into a metric 14mm x 1.5 thread. This is different from the AN fittings used in aftermarket parts. The OEM hard steel line also has an internal flare, although the degree of this flare is not known.
To identify the thread size of a metric fitting, you can use a caliper to measure the outer diameter (OD) in millimetres. This will give you the thread size, but not the thread pitch. For example, a caliper reading of 12.03mm indicates a likely 12mm thread, but the pitch could be 1.0 or 1.5, or something else. To determine the pitch, you would need to take additional measurements or use a thread gauge kit.
It's important to note that metric threads can be tapered or parallel. Tapered threads have walls that, if extended lengthwise, would eventually meet, while parallel threads have straight walls. The type of thread affects how the fittings are sealed. For example, a seal is required for parallel fittings in PORT applications. Additionally, metric threads can have different sealing surfaces, such as flared seats or ball/cone seats, which can impact compatibility.

The hard feed line from the tank is a -6an fitting
The hard feed fuel line from the tank in an Evo is a -6AN fitting. This refers to the size and type of fitting required to connect an aftermarket feed line to the stock hard fuel feed line. The car's feed itself is -6AN, and you can purchase adapters for the fuel line.
The -6AN fitting is a common size for fuel lines and is available from several retailers. It is also possible to purchase a complete -6AN fuel line kit, which includes all the necessary fittings and adapters.
It is important to note that OEM Japanese manufacturers do not use the AN system for their fittings. The OEM factory fitting threads into a metric 14mm x 1.5 thread, and the hard steel line has an internal flare. The degree of this internal flare is not known, and it may be necessary to find an aftermarket fitting that mates up with it perfectly.
Some people choose to redo their fuel lines in stainless steel or Kevlar, and it is important to ensure that the correct fittings and adapters are used to avoid any issues. It is recommended to seek advice from experienced individuals or professionals when making any modifications to fuel lines.

The feed hardline is 5/16 and the return hardline is 1/4
The terms "feed hardline" and "return hardline" refer to the fuel lines in a car engine. The feed hardline is the line that carries fuel from the tank to the engine, while the return hardline carries any unused fuel back to the tank. The size of these lines is important to ensure the smooth and efficient flow of fuel.
In the context of fuel lines, the measurements 5/16 and 1/4 refer to the outer diameter (OD) of the hard lines. The feed hardline, with a 5/16 OD, is larger than the return hardline, which has a 1/4 OD. These measurements are essential when selecting the appropriate fittings and adapters for the fuel lines.
For example, some car models, like the Honda Civic, require a 6AN line for the feed and a 4AN line for the return. However, the OEM factory fittings on Japanese cars may have different thread sizes, such as a metric 14mm x 1.5 thread. It is crucial to identify the correct fitting size to avoid leaks and ensure proper fuel delivery.
When upgrading fuel lines, it is recommended to use adapters that convert the factory lines to -AN fittings. These adapters provide a secure connection and help standardize the fuel delivery system. Additionally, using hose clamps can be an effective method for attaching braided lines to hardlines, creating a tight seal and preventing leaks.

The fuel line size for the return line between the fuel rail and the FPR is -8
The fuel line size for the return line between the fuel rail and the FPR is an important consideration when modifying a car's fuel system. In this case, the fuel line size in question is -8, which is larger than the commonly used -6 size.
The decision to use a -8 fuel line for the return line between the fuel rail and the FPR is likely based on the specific requirements of the vehicle and its engine. The fuel line size can impact fuel flow and pressure, and in some cases, a larger line may be necessary to accommodate higher horsepower and fuel consumption.
In the case of the Evo 8/9, for example, some owners have reported using a -6 fuel line for the return line between the fuel rail and the FPR. However, others have suggested that a -6 fuel line may not be sufficient for vehicles with higher horsepower and fuel consumption, and a larger -8 fuel line may be more appropriate.
It is important to note that modifying a car's fuel system, including the fuel line size, can affect performance and safety. It is always recommended to consult with a professional or a mechanic with experience in vehicle modifications to ensure that any changes made are safe and appropriate for the specific vehicle. Additionally, it is crucial to use high-quality components that are compatible with the vehicle's fuel system to prevent leaks and other issues.
