ACUiTY's -8AN to -8 O-Ring Boss (ORB) adapter is made from 7075-T6 aluminum for strength with a gently tapered interior for maximum flow. These were designed for use with ACUiTY's K-Series Fuel Rails, but they are perfect for use in any gas, ethanol, or gas/ethanol mix fuel system where a -8 ORB port must be adapted for a -8AN fuel line (which is a common size used in very high horsepower applications).
