AutoMeter Vac/Boost Gauge 2 5/8″ 30Inhg-30Psi Carbon Fiber

Description

Product Overview

AutoMeter’s Vac/Boost gauge is engineered for precision and durability, delivering reliable vacuum and boost pressure measurements for both marine and automotive environments. The gauge combines a robust mechanical dial with a clear, easy‑to‑read display, allowing technicians and hobbyists alike to monitor engine performance without the need for electronic assistance. Designed around a 2 5/8‑inch inlet, the unit fits seamlessly into standard instrument panels, offering a compact footprint while maintaining full functionality. With a pressure range of 0 to 30 psi, the gauge covers the typical vacuum and boost requirements of outboard motors, inboard diesel engines, and high‑performance gasoline vehicles, making it a versatile tool for a wide range of applications.

The housing is constructed from marine‑grade carbon fiber, a material chosen for its exceptional strength‑to‑weight ratio and resistance to salt‑water corrosion. This lightweight composite not only protects the internal mechanisms from harsh environmental conditions but also reduces overall weight, an important factor for performance‑oriented installations where every gram counts. The carbon‑fiber finish provides a sleek, modern aesthetic that complements both rugged workboats and polished automotive dashboards.

Key specifications include a 2 5/8‑inch (6.35 mm) thread size, a pressure range of 0‑30 psi (0‑2.07 bar), and a mechanical movement calibrated for high accuracy. The dial features a large, backlit pointer and graduated markings that are easy to read even in low‑light conditions. The gauge operates without batteries, relying on a fully mechanical system that eliminates the need for power sources and reduces potential points of failure. Its construction adheres to strict quality standards, and each unit undergoes rigorous testing for accuracy, durability, and leak resistance before leaving the factory.

Packaging includes the gauge itself, mounting hardware, and a concise installation guide. The product is covered by a standard one‑year warranty that protects against manufacturing defects, and AutoMeter provides additional support resources through its website and customer service channels. Whether installed on a recreational boat, a commercial vessel, or a performance car, this gauge offers dependable, real‑time feedback that helps users optimize engine tuning, diagnose issues, and maintain safe operating pressures.

Usage

In marine settings, the AutoMeter Vac/Boost gauge is an essential instrument for monitoring engine vacuum on outboard and inboard propulsion systems. Boaters rely on accurate vacuum readings to assess the health of fuel pumps, detect air leaks, and ensure optimal combustion efficiency. The gauge’s robust carbon‑fiber housing protects it from splashing seawater, UV exposure, and the constant vibration of marine engines, making it suitable for both recreational and commercial vessels. Installation is straightforward: the gauge mounts directly onto the existing vacuum line, providing immediate visual feedback during engine start‑up, cruising, and idle conditions.

Automotive enthusiasts and professional mechanics also benefit from the gauge’s ability to track boost pressure on turbocharged or supercharged engines. By observing real‑time boost levels, users can fine‑tune turbo wastegate settings, verify compressor performance, and prevent over‑boost scenarios that could damage engine components. The gauge’s clear mechanical dial eliminates the need for electronic interfaces, allowing it to be used in environments where electrical interference or limited power availability would be problematic. Its compact size fits easily into the instrument clusters of race cars, street‑legal performance vehicles, and even classic cars that require a period‑correct appearance.
