Adapter EFI 6an Fitting Ford Return Side Black

The Adapter EFI 6AN Fitting Ford Return Side Black by RUSSELL is a precision-engineered fuel line adapter designed specifically for modern Ford EFI (Electronic Fuel Injection) systems that require return-side fuel routing. This straight adapter transitions from a 6 AN male connection to Ford's OEM return-side EFI port, making it suitable for specific fuel system upgrades and conversions.

Constructed from aluminum and finished in black anodize, the Adapter EFI 6AN Fitting provides corrosion resistance and durability in engine bay environments. The black anodized coating protects against oxidation and fuel degradation while maintaining a clean, professional appearance in visible installations. RUSSELL's engineering ensures exact port geometry, which is critical for return-side applications where fuel pressure regulation depends on precise fitment to prevent leakage and backpressure issues.

This adapter is ideal for Ford owners upgrading to aftermarket fuel pumps, fuel rails, or custom fuel cells that utilize standard 6 AN hose fittings on the return line. It is compatible with various Ford EFI systems, but users should verify compatibility with their specific vehicle model to ensure optimal performance.
