Oil Pressure Sending Unit Adapter
This is the correct NPT Adapter to mount our Oil Pressure Sending Unit to the Buick 455 Block
Fits Buick Engines with 1/4″ NPT inlet & 1/8″ NPT Sending Units
Note: This fitting is to be used with the current aftermarket Sending Units. If you are fortunate enough to have a Factory Sending Unit that still works you will not need any fittings.
