Description
If you’re running forced induction or a high-pressure fuel system, you need a reliable way to monitor real-time pressure without sacrificing flow or introducing weak points in your line. The Earls Gauge Adapter Fitting provides a clean, direct port for your pressure gauge while maintaining full 4 AN flow capacity—no restrictive tees or jury-rigged solutions required. This is precision instrumentation for builders who demand accuracy and durability.
The black anodized aluminum construction resists corrosion and integrates seamlessly into any modern engine bay. Installation is straightforward: bolt the adapter into your 4 AN fuel or boost line, thread your gauge into the 1/8″ NPT port, and you’re reading live pressure with confidence.
