AN (Army-Navy) fuel lines are a standardised type of fitting often used in high-performance applications. They are known for their reliability and come in various sizes. AN fittings are a superior connection to a traditional hose clamp and are often used with braided fuel lines, which are an upgrade on the basic metal or rubber fuel lines. Braided fuel lines are made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core.

Barbed fittings are serrated ends that grip onto the fuel line
Barbed fittings are a simple and effective way to connect fuel lines. The serrated ends of the fitting grip onto the fuel line, creating a secure connection. This type of fitting is often used with rubber or plastic fuel lines, which are flexible and easy to work with. To ensure a tight seal, hose clamps are used to secure the connection.
One advantage of barbed fittings is their affordability. As basic fuel line fittings, they are significantly cheaper than other options such as quick connect fittings or AN fittings. This makes them a cost-effective choice for those on a budget. Additionally, barbed fittings are suitable for low-pressure applications, making them a good choice for certain types of engines and vehicles.
However, it's important to note that barbed fittings may not be suitable for all situations. For high-performance applications or engines with higher horsepower, an upgrade to braided fuel lines and AN fittings may be required. AN (Army-Navy) fittings are a standardized type of fitting known for their reliability and performance. They come in various sizes and can be more expensive, especially for specialized or larger sizes.

Quick connect fittings are designed for convenience and easy installation
Quick connect fittings are often used in conjunction with other types of fuel lines, such as metal, rubber, braided, and PTFE-lined fuel lines. Metal fuel lines are typically made from steel or aluminium, while rubber fuel lines are made from rubber or other elastomeric materials. Braided fuel lines, on the other hand, are made from a metal or synthetic fibre braid that is wrapped around a rubber or other elastomeric core.
Quick connect fittings are also a good option for those who want a reliable connection without the need for specialised tools or expertise. They are designed to be user-friendly and straightforward to install, making them a convenient choice for many applications.
In terms of cost, quick connect fittings are typically more expensive than basic fuel line fittings, but they offer increased convenience and ease of use. They are available in a range of sizes and can be purchased for as little as $5 per fitting, although prices can go up to $20 or more depending on the specific requirements and features.

Push-lock fittings feature a push-to-connect design, making them easy to install
Military or AN-style fuel lines are a standardised type of fitting often used in high-performance applications. They are known for their reliability and come in various sizes. Braided lines are an upgrade as they flex and utilise AN fittings, which are a superior connection to a traditional hose clamp.
Push-lock fittings, also known as push-on or barbed fittings, feature a push-to-connect design, making them easy to install. They are commonly used with push-lock style hoses and are designed for quick and easy connections. The barbed end easily inserts into the hose, and a hose clamp is used to secure the connection. This makes the process quick and user-friendly. Push-lock fittings can be installed without the need for specialised tools, and they can be reused multiple times. The barbed design ensures a tight grip on the hose, preventing it from slipping off under pressure. When properly installed with a hose clamp, push-lock fittings provide a reliable and leak-proof connection. They are commonly used in situations where ease of installation and reusability are important, but the system pressure does not exceed the fitting's rated capacity.

Braided lines are an upgrade as they flex and utilize AN fittings
Braided lines are an upgrade from the standard steel or rubber fuel lines that are found in most cars. Braided lines are made from a metal or synthetic fibre braid that is wrapped around a rubber or elastomeric core. This design allows them to flex, which is an advantage over the standard steel or rubber lines. Braided lines also utilise AN (Army-Navy) fittings, which are a standardised, reliable, and high-performance type of fitting. AN fittings are often used in high-performance applications and come in various sizes. They are more expensive than basic fuel line fittings, starting at around $10 and increasing significantly for specialised or larger sizes.
Braided lines are a popular choice for those running EFI, as an upgrade to the fuel lines is required in this case. They are also a good option for those seeking a flexible fuel line with superior connections when compared to traditional hose clamps. If you are running a basically stock carbureted engine in your car, a basic metal fuel line will likely suffice.
