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