Gauge Adapter #8M to #8

The Gauge Adapter #8M to #8 from EARLS is a precision AN fitting engineered to bridge 8 AN female and 8 AN male ports while accommodating a 1/8 inch NPT gauge line connection. This straight adapter serves as an essential component in high-performance fuel, oil, and coolant systems where pressure monitoring is critical. Whether you're building a custom race engine, maintaining a performance transmission cooler, or integrating aftermarket monitoring into an existing circuit, this gauge adapter enables you to tap into your system's pressure data without compromising flow or system integrity.

Constructed from aerospace-grade aluminum and finished in vibrant blue anodize, the Gauge Adapter #8M to #8 resists corrosion and oxidation in demanding underhood environments. The straight port orientation minimizes turbulence and pressure loss while the NPT gauge port threads accommodate standard 1/8 inch instrument fittings found on OEM and aftermarket gauges. The compact 1.55 x 0.95 x 2.85 inch footprint and lightweight 0.06 lb design make it ideal for tight engine bays where space is at a premium, and the blue anodize provides both durability and visual clarity in complex plumbing layouts.

Performance builders, hot rodders, and mechanics who demand reliable pressure diagnostics will appreciate this adapter's seamless integration into 8 AN hose systems. Installation is straightforward—simply position the adapter between your 8 AN male and female lines, thread your gauge sender or transducer into the NPT port, and secure all connections with appropriate AN wrenches. Compatible with any 1/8 NPT instrument fitting, this adapter works equally well with mechanical pressure gauges, electronic pressure transducers, or fuel pressure regulators, making it an indispensable tool for system tuning and real-time monitoring.
