Vertical Pressure Gauges GM Metric

The Vertical Pressure Gauges GM Metric by LONGACRE delivers precision monitoring for engine diagnostics and performance tuning on General Motors platforms. Whether you're diagnosing fuel system anomalies, verifying oil pressure under load, or validating transmission line pressure during custom calibration work, this metric-scaled gauge provides the accurate real-time data serious mechanics and enthusiasts demand. The vertical orientation mounts cleanly into custom gauge clusters or standalone panels, making it ideal for both shop diagnostics and high-performance build integration.

Built to LONGACRE's exacting standards, this gauge features metric calibration optimized for GM fuel injection, hydraulic, and lubrication systems—eliminating conversion errors when working with factory service specifications. The vertical design reduces parallax error during readings and simplifies panel layout in tight engine bays or custom dash fabrications. Robust construction withstands vibration, temperature cycling, and the electrical noise common to high-output engine compartments, ensuring stable needle response and long-term reliability in both street and competition environments.

This gauge fits seamlessly into GM LS swaps, modern LT platforms, and classic Chevy restorations where metric documentation is standard. Mechanics installing custom fuel systems, upgrading to high-flow fuel pumps, or validating turbo boost lines will appreciate the clarity and durability this LONGACRE instrument delivers. Its compact footprint (5.1 × 3.5 inches face) accommodates dashboard vaults, A-pillar mounts, or auxiliary gauge pods without imposing installation constraints. Pair with quality sender units and stainless braided line for maximum accuracy and professional appearance.
