Why Use an EFI Quick-Disconnect AN Adapter?

Factory EFI systems commonly use quick-disconnect fuel rail connections that are incompatible with aftermarket AN fuel lines. This adapter converts those factory-style connections into a standard 6AN male fitting, allowing easy integration with braided hose and performance fuel system components.

Translation: less fighting with factory clips, more actual progress.

Features

• 6AN male flare fitting
• 3/8-inch EFI female quick-disconnect connection
• Lightweight billet aluminum construction
• Precision CNC-machined design
• Leak-resistant sealing surfaces
• Corrosion-resistant anodized finish
• Compatible with braided AN fuel lines
• Supports high-flow EFI fuel systems
• Suitable for gasoline, E85, ethanol blends, and race fuels

[Size] The thread size of 6an is nine/sixteen-18UNF. The ID of the screw is 3/8 inch.

Common Applications

• EFI fuel rail conversions
• LS swap fuel systems
• Return-style fuel setups
• Turbocharged applications
• Fuel pressure regulator installations
• Custom AN fuel plumbing
• High-horsepower street builds
• Drift and drag racing vehicles
• Modern fuel injection upgrades

[Seal] The 6an flare efi fitting is sealed at 37 degree perspective to steer clear of leakage.

Perfect for Aftermarket Fuel Systems

AN fuel plumbing has become the standard for modern performance builds because it offers improved durability, serviceability, and fuel compatibility compared to factory rubber and plastic fuel line systems. This adapter allows enthusiasts to retain factory fuel rail compatibility while upgrading the rest of the fuel system to support higher flow and increased reliability.

Especially important when your fuel demand now resembles a small commercial airport.

[Parameter] Working pressure: 1500psi; Temperature vary: -forty°F to 250°F.

Simplifies Fuel Line Routing

The compact adapter design allows easy integration into tight engine bays while providing a clean professional appearance. It also simplifies fuel system maintenance by allowing easy AN hose removal and service compared to factory quick-connect systems.

Because removing OEM fuel clips with a screwdriver and blind optimism gets old fast.

[Material] Manufactured from aluminum alloy 6061-T6.
[Application] Widely utilized in engine fuel rail, ls swap, transmission cooler, go back line, fuel sensor, and the like.
