For the racer that may have a large Hilborn fuel pump with a large ORB outlet port that needs to be reduced to a smaller ORB size, this fitting is just the ticket. Racer can reduce a -16 ORB port to a female -12 ORB female port to make a more common fuel shut off fit with no issues.
Fitting is made from steel and cad plated for corrosion protection. Includes O-ring on the -16 port side.
