IAG Fuel Pressure Gauge Black – Universal

IAG Fuel Pressure Gauge — Black — Universal

Monitor Fuel Pressure for Tuning and Diagnostics
The IAG Fuel Pressure Gauge is a black universal fuel pressure gauge designed for use with IAG fuel rail and FPR installations. Monitoring fuel pressure is important for tuning accuracy and diagnosing fuel delivery issues — especially important on high-horsepower builds where lean conditions can cause engine damage. Compatible with IAG’s 90-degree gauge adapter for mounting flexibility.

DETAILS

• Black finish
• Universal fitment — compatible with IAG fuel rail and FPR systems
• Compatible with IAG 90-degree gauge adapter
• Included in IAG PTFE Fuel System Kits
• Can be purchased separately for existing IAG fuel system installations

Why Monitor Fuel Pressure
Fuel pressure is the primary indicator of fuel system health in a high-performance Subaru. Low fuel pressure under boost can cause lean conditions that damage pistons and other engine components. Having a gauge allows the tuner and driver to monitor fuel pressure during tuning sessions and verify the fuel system is performing as intended.

Gauge Adapter Compatibility
This gauge is compatible with IAG’s 90-degree gauge adapter, which allows the gauge to be positioned for easy visibility in the engine bay without requiring a straight-line mounting orientation.

Part of the IAG Fuel System Kit
This gauge is the same unit included in IAG’s complete PTFE Fuel System Kits. If you are building a custom fuel system from individual components and want the correct gauge, this is the part to use.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

The IAG fuel pressure gauge is a small but important tool for any high-performance fuel system build. If you are running a custom fuel system and do not have a pressure gauge, add one. The cost of the gauge is trivial compared to the cost of a lean engine failure.
