#6 to 3/8 NPT Fuel Press Adapter w/ 1/8 NPT Port

The XRP #6 to 3/8 NPT Fuel Press Adapter with 1/8 NPT Port is a precision-engineered fuel system fitting designed for high-performance engine builds and fuel pressure monitoring applications. Manufactured by XRP-Xtreme Racing Products, this adapter converts AN-6 line connections to NPT threaded ports while incorporating a dedicated gauge port for real-time fuel pressure diagnostics. Black anodized aluminum construction provides corrosion resistance and durability across demanding automotive environments.

This fuel press adapter addresses a critical requirement in fuel system architecture: consolidating multiple connection points into a single, compact junction. The 6 AN male inlet accepts standard AN-6 fuel line fittings, while the 3/8 NPT male outlet threads into fuel rails, pressure regulators, or accumulator tanks. The integrated 1/8 NPT gauge port accommodates fuel pressure transducers or analog mechanical gauges without requiring a separate T-fitting. Aluminum construction keeps overall weight minimal—critical in racing and high-output engine applications where unsprung mass directly impacts performance.

Fuel system builders, engine tuners, and motorsports technicians rely on this fitting for EFI fuel rail installations, dual-fuel systems, and pressure-monitored fuel delivery setups. The NPT threading standard ensures broad compatibility with OEM and aftermarket fuel system components. Users working with carbureted-to-EFI conversions, forced-induction fuel systems, or custom engine builds benefit from the adapter's ability to consolidate gauge and delivery lines into a single manifold point, reducing clutter and improving diagnostics accessibility.

XRP-Xtreme Racing Products specializes in AN-fitting adapters and fuel delivery components for racing and street performance applications. This adapter is commonly paired with fuel pressure gauges, electronic fuel injection controllers, and high-flow fuel pump systems where pressure monitoring and multi-point fuel distribution are essential. Compact dimensions allow installation in tight engine bay environments where space is at a premium.
