Dan,
The unit was supplied by Speed Hut to Factory Five and was included in their complete kit package. It is supposed to be compatible with their gauge. I did install an arm that comes out of the block with a terminal wire at the end of the arm which goes to the red light indicator on the dash for low
oil pressure, and the
Oil Pressure Sending unit is inserted into that arm. It is a back up safety measure. Is there a possibility it is causing the
Oil Pressure Sending unit to go bad ? We thought maybe we were getting air bubbles into the unit ??
