Fuel Pressure Take-Off Adapter -8an

The Russell Fuel Pressure Take-Off Adapter -8AN is a straight-through gauge fitting designed to split fuel pressure monitoring into an existing fuel system without interrupting main flow. This 8 AN male-to-female adapter incorporates a 1/8-inch NPT port for direct gauge installation, allowing operators and technicians to monitor fuel system pressure in real-time during diagnostics, performance tuning, or high-demand operational scenarios.

Constructed from aluminum and finished in blue and red anodized coating, this take-off adapter is built for durability in fuel environments where corrosion resistance matters. The straight-through design minimizes turbulence and pressure drop across the fitting, critical for accurate gauge readings. The 1/8-inch NPT gauge port accepts standard 0–100 PSI or 0–150 PSI fuel pressure gauges, providing flexible instrumentation options. Part number 670350 meets the dimensional specifications essential for tight engine bay installations and aftermarket fuel system configurations.

This fitting serves users who require immediate fuel pressure visibility—engine builders tuning carburetor or EFI systems, off-road recovery teams running auxiliary fuel systems, marine operators working in salt-air environments, and tactical logistics personnel managing fuel system integrity under field conditions. Weighing just 0.07 lbs, the adapter adds negligible mass while maintaining the structural integrity required for sustained pressure cycling in demanding applications.

Russell has long established itself as a reliable source for fuel system fittings in both civilian performance and professional markets. This take-off adapter represents the precision engineering expected from a brand trusted to handle critical fuel delivery plumbing where accuracy and reliability cannot be compromised.
