-6AN Fast Flow Fitting

The -6AN Fast Flow Fitting is a precision bulkhead connector engineered for high-performance fuel system installations where flow rate and reliability are non-negotiable. Designed by JAZ for builders running aftermarket fuel cells and custom fuel delivery systems, this straight-through fitting eliminates restriction points that plague standard fuel line connections. Whether you're upgrading a naturally aspirated engine's fuel supply or supporting a turbocharged platform demanding consistent pressure, this fitting bridges your hardline to your fuel cell with minimal turbulence and maximum durability.

Construction centers on aluminum body with blue anodized finish, providing corrosion resistance and weight savings critical in competition and custom applications. The 6 AN male-to-male bulkhead configuration allows seamless integration through firewall or tank mounting points without additional adapters, while included PTFE gaskets ensure leak-free sealing under varying fuel pressures and temperature cycles. The fast-flow design prioritizes internal passage geometry to reduce pressure drop—essential when fuel pumps operate at their efficiency threshold and every PSI margin matters for system performance and pump longevity.

This fitting serves custom fuel system builders, vintage car restorers installing modern fuel cell technology, and performance enthusiasts upgrading stock fuel delivery. The straight bulkhead design excels in tight engine bays where 90-degree or swivel fittings cannot fit, making it ideal for mid-mounted fuel cells in custom chassis or forward tanks requiring direct firewall penetration. Installation requires only standard wrench access; torque to manufacturer specifications and pair with appropriate -6AN hose and clamps for a system that flows fuel efficiently from cell to carburetor, EFI fuel rail, or dual-pump configuration.
