Overview

The Marshall CW00015 is a compact, liquid-filled pressure gauge designed for accurate monitoring in the 0–15 PSI range. Its stainless steel case and bezel provide excellent corrosion resistance and durability, making it well suited for automotive fuel pressure monitoring, carbureted engine setups, and other low-pressure applications. The liquid fill dampens needle oscillation caused by vibration and pressure pulsation, allowing you to take quick, reliable readings even while equipment is running.

Featuring a clean white dial face with a high-visibility red pointer, the CW00015 is easy to read despite its compact 1.5-inch diameter. The 1/8" NPT center back connection is a widely used standard, simplifying installation in most fuel lines and manifolds. The included Easy-Vent Nipple Plug allows you to purge trapped air from the gauge case, which is essential for maintaining the accuracy and responsiveness of the liquid-filled mechanism over the life of the gauge.

Pros & Cons

👍 Pros

  • Liquid-filled design dampens needle vibration for steady, easy-to-read measurements under pulsating conditions.
  • Stainless steel case and bezel resist corrosion and withstand harsh operating environments.
  • Compact 1.5-inch dial fits in tight spaces without sacrificing readability thanks to the white dial and red pointer.
  • Easy-Vent Nipple Plug allows simple air removal to maintain accurate readings over time.

👎 Cons

  • 0–15 PSI range is limited to low-pressure applications and is not suitable for higher-pressure fuel injection systems.
  • 1.5-inch dial size, while compact, may be harder to read at a distance compared to larger 2- or 2.5-inch gauges.
  • 1/8" NPT back connection may require an adapter for systems using different thread sizes or side-mount configurations.
  • No included mounting bracket or hardware, so you will need to source your own installation fittings.

Frequently Asked Questions

The Marshall CW00015 measures pressure from 0 to 15 PSI, making it suitable for low-pressure fuel systems and similar applications.
The gauge case is filled with liquid (typically glycerin) to dampen needle vibration caused by pulsation or mechanical shock, resulting in steadier, more accurate readings.
The gauge uses a 1/8" NPT center back connection, which is a standard pipe thread fitting widely used in fuel and pressure systems.
The Easy-Vent Nipple Plug allows you to release trapped air from the liquid-filled case, ensuring the gauge provides accurate readings and the needle moves freely.
