Fuel Pressure Gauge 1-1/2" Liquid Filled 0-100 psi Pressure White Face

Engineered for EFI systems, this Aeroflow GEN 2 1-1/2-inch fuel pressure gauge delivers precise readings from 0 to 100 psi, giving you clear visibility under any engine bay conditions. The white dial with a bold black pointer ensures quick, at-a-glance monitoring during tuning and daily driving alike.

Key features designed for performance diagnostics:

• Diameter and range: 1-1/2" gauge with a 0–100 psi scale, ideal for EFI fuel pressure monitoring and quick system checks.
• Reading clarity: white face paired with a high-contrast black pointer for legible readings even on bright days or in dim engine compartments.
• Mounting fit: 1/8" NPT male thread provides reliable compatibility with common EFI fittings and fuel rails.
• Gen 2 evolution: part of the Aeroflow GEN 2 line, featuring redesigned face, updated pointer, and a sleek black outer housing for a modern, professional look.
• Vibration management: available in liquid-filled designs to dampen needle flutter in high-vibration environments (and non-liquid-filled variants exist within the same gauge family).

Why this gauge stands out for EFI applications

EFI systems demand stable, repeatable readings to diagnose fuel delivery issues quickly. The liquid-filled option in this gauge minimizes needle bounce that can occur from engine vibrations, enabling steadier readings when you’re monitoring fuel pressure during cold starts, throttle transitions, or performance tuning. The white dial and distinct pointer help you spot pressure changes at a glance, reducing the time spent glancing at the gauge during peak tuning sessions.

Practical use cases

• EFI-equipped street and race cars where accurate fuel pressure monitoring is critical for tune accuracy and reliability.
• Diagnostics during startup, acceleration, and load changes to verify pump performance and regulator function.
• Custom builds and engine swaps where a compact 1-1/2" gauge fits tight dash or cockpit panels while delivering clear data.

What you can expect in your setup

• Clear, readable fuel pressure data at a glance, helping you confirm proper fuel delivery or quickly detect pressure drops.
• Reliable interfacing with EFI components thanks to a standardized 1/8" NPT male connection.
• Aesthetically coordinated with other Aeroflow GEN 2 gauges, featuring a black housing and updated dial orientation for a cohesive performance cockpit look.
