AEM Electronics Liquid Filled Fuel Pressure Gauge - Black, Black

The AEM Electronics Liquid Filled Fuel Pressure Gauge allows you to monitor fuel system pressure directly at the source. It connects to any 1/8 NPT port such as on an AEM fuel rail or adjustable pressure regulator and uses silicone fluid damping to deliver steady, accurate readings between 0 100 PSI.Discover the key features of this pressure gauge and how they contribute to accuracy, durability and ease of use in your setup:1/8 NPT Male Thread Fitting: Designed to mount directly into a compatible fuel rail or regulator, this fitting provides a tight and secure seal that allows you to measure pressure exactly where it matters, ensuring precise system tuning and fuel delivery control.0 100 PSI Analogue Readout: The mechanical dial clearly displays fuel pressure within a useful 0 to 100 PSI range, giving you real-time feedback to help diagnose issues or confirm adjustments during setup, maintenance or tuning.Silicone Fluid Filling: The case is filled with silicone oil to dampen needle movement caused by engine vibration, which improves readability and delivers more stable readings for consistent adjustments and better reliability.Stainless Steel Gauge Housing: Built with a corrosion-resistant stainless steel case, this housing protects the internal mechanism from environmental damage, helping extend gauge life and maintain accuracy in exposed engine bays.Black Finish: The external housing is finished in black for a low-reflection, functional appearance that blends easily into your engine bay layout while offering added surface protection.By fitting this gauge directly to a key point in your fuel system, you get immediate insight into system pressure without relying on remote sensors or digital displays. It s a useful addition to your tuning setup, especially when making adjustments to regulators or verifying consistent supply to the injectors. With its robust design and simple installation, this gauge is a smart choice for refining fuel delivery and diagnosing pressure-related issues.Dimensions: 38mm (1.5") diameter
