Inline Gauge Adapter #8 x #8 Male Black

The Inline Gauge Adapter #8 x #8 Male Black by FRAGOLA is an essential fitting for any serious performance fuel system or hydraulic line setup. This straight-port gauge adapter connects two 8 AN male ports while providing a dedicated 1/8 in NPT gauge port for real-time system monitoring. Whether you're building a high-flow fuel delivery system, installing a custom coolant loop, or setting up precision pressure monitoring on a forced-induction engine, this adapter bridges the gap between your primary line and diagnostic instrumentation.

Constructed from aluminum and finished in black anodize, the FRAGOLA 495003-BL delivers durability and corrosion resistance in demanding underhood environments. The straight design minimizes turbulence and pressure loss compared to 90-degree configurations, critical when every PSI matters in fuel injection tuning or transmission cooling circuits. The 1/8 in NPT gauge port accepts standard pressure senders and analog gauges, allowing you to dial in fuel pressure, oil pressure, coolant temperature, or transmission fluid pressure with factory-quality fittings. At just 0.07 lbs, the compact footprint (1.55 x 1.25 x 4.15 inches) fits tight engine bays where space is at a premium.

Engine builders, tuners, and weekend warriors rely on this adapter when transitioning from stock fuel rails to custom fuel systems or upgrading cooling infrastructure on turbocharged and supercharged platforms. The dual 8 AN male configuration ensures compatibility with braided hose assemblies and rigid AN-spec plumbing found in quality aftermarket fuel systems and hydraulic brake upgrades. Installation is straightforward—thread the NPT gauge port into your chosen sender or gauge head, then secure the AN fittings to your primary line using standard -8 hose or hard-line tubing. This is production-quality fitment that won't leak or weep under pressure cycling.
