Radium Engineering Fuel Pressure Gauge w/ 6AN Inline Adapter

Monitor your fuel system with confidence using the Radium Engineering Fuel Pressure Gauge. Designed for all fuelling applications — from street builds to high-power race setups — this gauge delivers accurate, stable readings you can trust under load. The silicone-filled dial eliminates needle vibration, giving you a clear, steady readout even at high RPM. Paired with a 6AN inline adapter for a clean, tool-free installation into any AN-based fuel system.

• Reads 0-100 PSI (0-6.9 BAR) with ±2% accuracy
• Silicone-filled dial prevents needle vibration for stable readings
• Acrylic lens with rugged stainless steel 1-5/8" OD case (1-3/4" OD bezel)
• Nickel-plated male 1/8" NPT fitting
• Black bezel and housing
• Includes 6AN inline adapter for direct integration into AN fuel lines

NOTES:

1. The internal silicone bubble is normal and does not affect gauge performance.
2. Overpressurising can permanently misalign needle calibration — do not exceed rated pressure.
3. PTFE thread sealant paste should always be used on NPT threads.
