1/2 Male EFI Quick Connect to 8an Male

The 1/2 Male EFI Quick Connect to 8AN Male fuel line adapter is a straight stainless steel fitting engineered for high-performance fuel system transitions. This adapter bridges EFI (Electronic Fuel Injection) quick-disconnect couplings to AN (Army-Navy) male threaded ports, making it essential for custom fuel system builds, motorsport applications, and engine swaps where OEM fuel line routing doesn't align with aftermarket injection systems or fuel delivery components.

Constructed from stainless steel in a natural finish, this fitting resists corrosion from ethanol-blended fuels and moisture exposure—critical where fuel system components operate under pressure or in high-vibration environments. The straight geometry eliminates flow restriction and simplifies installation in tight engine bays. The 1/2-inch EFI male quick-connect interface accepts standard fuel pressure-test gauges and OEM EFI fuel line couplings, while the 8AN male outlet threads directly into 8AN female ports on fuel rails, regulators, filter housings, or custom manifolds. Weighing only 0.12 lbs and measuring 3.9 inches in length, this adapter integrates seamlessly without adding significant bulk.

This adapter suits engine builders, performance shops, and enthusiasts performing EFI conversions on carbureted platforms, upgrading to aftermarket fuel systems, or troubleshooting fuel delivery with diagnostic equipment. It's commonly used in drag racing, off-road racing, and street performance builds where precision fuel system architecture is non-negotiable. The quick-connect end allows rapid coupler engagement and disengagement—valuable during tuning sessions, fuel system bleeding, or component swaps without breaking the full fuel line.
