Remove all of the old liquid gasket from the switch and switch mounting hole.
Apply a very small amount of liquid gasket to the new oil pressure switch threads, then install the oil pressure switch.
NOTE: Using too much liquid gasket may cause liquid gasket to enter the oil passage or the end of the new oil pressure switch.
