Fuel Line Fittings FAQs

Find answers to our most common questions below.

Fuel line fittings connect fuel lines to various components in your fuel system, ensuring a secure and leak-proof connection. They come in different styles and materials suited for various fuel system configurations.

Fuel line fittings are typically made from aluminum, stainless steel, or brass. AN fittings are often made from lightweight aluminum for high-performance applications, while stainless steel is used for added durability and corrosion resistance.

AN fittings are high-performance fuel fittings commonly used in motorsport and high-performance applications. AN fitting sizes are measured in 1/16-inch increments, such as -6AN or -8AN, allowing for precise fuel flow in custom fuel systems.

To install fuel line fittings like AN fittings or hose ends, ensure that the fuel hose is cut cleanly and appropriately sized for the fitting. Use the correct tools to tighten the fittings without over-torquing, and always check for leaks after installation.

The appropriate AN fitting size depends on the fuel line diameter and specific flow requirements of your fuel system. For example, a -6AN fitting is typically used for smaller fuel lines, while -8AN or larger may be needed for high-flow applications.

A hose end fitting connects the end of a fuel hose to a fuel component, such as a fuel rail or pump. Hose ends are available in different AN fitting sizes and angles to suit custom fuel line routing and installation.

AN fittings are not directly compatible with standard fuel hose fittings due to different thread sizes and sealing methods. However, adapters are available to connect AN fittings to standard components if needed.

Fuel line fittings are essential for ensuring a secure and leak-free connection in your fuel system. At Quantum Fuel Systems, we offer a wide selection of AN fittings, fuel hose fittings, hose ends, and other fuel fittings to meet your specific needs.
