O-Ring Boss to AN Port Fittings
The AN port is also known as O-ring boss. AN O-ring adapter fittings are just what you need to connect AN fuel lines to AN O-ring ports.These adapter fittings are designed with a full-flow radius transition from the port opening to the AN flare. Each fitting is CNC-machined from billet aluminum and is anodized for durability and corrosion resistance. The O-Ring side of the adapter is what screws into the fuel rail, fuel pressure regulator, fuel filter, fuel pump etc. The AN flare side is what connects to the female hose end.
Note: On the drop down menu when selecting the size you need, the first number is the flared side and the 2nd number is the O-ring boss side (ORB).
Example: AN 8 to AN 8 ORB
