6AN オスフレア to M14x1.5 オスインバーテッドフレア アダプター

Used this to connect my fuel rail to the stock hard line and the thread engagement was perfect, no leaks on the first try. The inverted flare seats nicely without needing excessive torque.

Finally found an adapter that mates my 6AN lines to the M14x1.5 port on the fuel rail without any leaks. The inverted flare seat mates up perfectly and the hex section gives good wrench clearance.

The threads machined perfectly onto my Holley regulator without any binding, and the hex body gave me plenty of grip for a solid torque. This little adapter solved my fuel system puzzle in five minutes flat.
