90 Degree -6AN Male to 5/16in EFI Line

The 90 Degree -6AN Male to 5/16in EFI Line adapter from Vibrant Performance is purpose-built for fuel injection system modifications where space constraints or routing challenges demand precision fitting. This 90-degree adapter serves as a critical interface between -6AN hose terminations and 5/16-inch EFI hard lines, making it essential for custom fuel system fabrication, carbureted-to-injected conversions, and high-performance engine builds. Whether you're upgrading a classic engine bay or engineering a tight fuel rail configuration, this adapter ensures leak-free, reliable fuel delivery without compromise.

Constructed with OEM-quality materials, the 90-degree male connector integrates -6AN SAE port sizing with 5/16-inch line compatibility, allowing seamless transitions between hose and hard-line sections in modern EFI systems. The angled design minimizes bending stress on fuel lines while reducing turbulence at the connection point—critical for maintaining consistent fuel pressure under load. Vibrant Performance's precision engineering ensures JIC-compliant threading and consistent bore diameter, preventing pressure drops and fuel atomization issues that plague inferior adapters. The compact footprint (3.54 x 0.75 x 6.3 inches) and minimal weight (0.07 lbs) make installation in tight engine compartments practical without sacrificing durability.

This adapter excels in street rod fuel systems, LS engine conversions, turbocharged applications, and any platform requiring custom fuel line routing around headers, intake manifolds, or intake manifold mounted fuel rails. Professional tuners and DIY enthusiasts building carburetor-to-fuel-injection systems benefit from its flexibility, allowing custom plumbing layouts without compromising flow or safety. Installation pairs seamlessly with -6AN hose rated for fuel service and standard 5/16-inch EFI tubing, ensuring compatibility with industry-standard fuel system components. For builders demanding reliability in modified fuel systems, this Vibrant Performance adapter delivers the precision fitting and flow integrity expected in professional engine work.
