The AEM 0–100 PSI liquid-filled mechanical pressure gauge is a 1/8" NPT instrument designed to mount directly to an AEM fuel rail or any 1/8" NPT port. It features a center-back 1/8" NPT connection for easy installation, an acrylic lens for clear reading, silicone fill for vibration dampening, and a black stainless steel case to protect the gauge in engine-bay environments.
