Earl's Performance AT100199ERL Fuel Pressure Gauge Adapter - 6 AN Male to Female with 1/8 NPT Port

The Earl's Performance AT100199ERL is an inline fuel pressure gauge tee adapter designed to provide a convenient 1/8 inch NPT port for installing fuel or oil pressure gauges in AN fuel line systems. This precision-engineered adapter features -6 AN male threads on one end and -6 AN female threads on the other, allowing inline installation while maintaining continuous fuel flow through the system.

Key Features:

• Constructed from aerospace-grade 6061-T6 aluminum for exceptional strength and durability
• Hard-anodized black finish that penetrates aluminum for superior wear and corrosion resistance
• 1/8 inch NPT female gauge port located in the hex body for direct or remote gauge mounting
• -6 AN male to -6 AN female configuration accommodates popular fuel line sizes
• Straight inline design maintains low-profile installation
• Compatible with both fuel and oil pressure monitoring applications
• Made in USA with precision CNC machining for accurate thread engagement

This adapter allows you to tap into your fuel system without cutting lines or adding bulky tee fittings. The integrated gauge port accepts standard 1/8 inch NPT pressure sensors or mechanical gauge fittings. The Ano-Tuff hard anodizing process provides a durable finish that lasts twice as long as traditional anodizing while giving your engine bay a professional, aggressive appearance. Ideal for EFI conversions, performance builds, and racing applications where accurate fuel pressure monitoring is critical.
