AEM 0-100 PSI Liquid Filled Mechanical Pressure Gauge - 1/8 NPT

AEM 0-100 PSI Liquid Filled Pressure Gauge (1/8 NPT) | High-Accuracy Fuel & Oil Gauge

Monitor fuel and fluid pressure accurately with the AEM 0-100 PSI Liquid Filled Mechanical Gauge (1/8" NPT center back connection). Silicone-dampened & durable.

The AEM 0-100 PSI Liquid-Filled Mechanical Pressure Gauge (Part # 30-2135-100) is a high-precision monitoring instrument engineered specifically for performance automotive applications. Featuring a compact 1.5-inch diameter body enclosed in a heavy-duty black stainless steel case, this gauge delivers dependable, real-time pressure readouts under demanding under-hood conditions.

It features a male 1/8" NPT center-back fitting, making it a direct-fit solution for AEM fuel rails, adjustable fuel pressure regulators (AFPR), oil sandwich plates, and aftermarket fuel distribution blocks. Designed with internal silicone filling, the gauge absorbs aggressive engine vibrations and pressure spikes, preventing needle bounce and protecting the internal movement for consistent accuracy and extended lifespan. A crystal-clear acrylic lens ensures crisp readability at a glance.

Best Uses

  1. EFI & Fuel System Tuning: Directly mounting to an AEM fuel rail or external fuel pressure regulator to set, adjust, and monitor static fuel pressure.
  2. Under-Hood Diagnostics: Spot-checking baseline pressure or diagnosing fuel delivery issues, faulty pumps, or clogged filters directly from the engine bay.
  3. Fluid Pressure Monitoring: Threading into 1/8" NPT ports on oil sandwich plates or auxiliary distribution blocks to check engine oil pressure or transmission fluid lines.
  4. Nitrous & Boost/Pneumatic Systems: Checking bottle pressure or regulated auxiliary pressure lines in performance applications operating under 100 PSI.

Features

  1. Silicone Liquid-Filled Damping: Internal liquid filling stabilizes the movement needle against high engine vibrations and pressure surges for smooth, legible readings.
  2. Standard 1/8" NPT Center-Back Fitting: Universally compatible threaded connection installs seamlessly onto fuel rails, regulators, and distribution blocks.
  3. Black Stainless Steel Housing: Rugged, corrosion-resistant 1.5-inch case built to withstand heat and chemical exposure under the hood.
  4. 0 to 100 PSI Measurement Range: High-contrast dial face optimized for modern electronic fuel injection (EFI) pressure demands.
  5. High-Clarity Acrylic Lens: Provides impact resistance and anti-glare protection for quick visual reference.

Benefits

  1. Vibration-Proof Precision: The liquid filling prevents rapid needle chatter caused by engine harmonics, giving you steady, accurate readings.
  2. Plug-and-Play Compatibility: Direct fitment with standard 1/8" NPT ports eliminates the need for complex adapters or extra plumbing.
  3. Compact Under-Hood Fitment: The 1.5" mini footprint allows it to sit cleanly in tight engine bays without interfering with surrounding components.
  4. Enhanced Hardware Longevity: Silicone damping protects internal mechanical gears from shock wear, ensuring long-term reliability.
  5. Instant Visual Troubleshooting: Allows mechanics and tuners to quickly verify fuel or oil pressure without setting up electronic logging gear.
