Brad, 

Not sure what you mean, exactly, but the 'sensor' is a bulb filled with ether which pressurizes a bourdon tube in the gauge. You need a good seal around the capillary tube that comes out of the nut/plug that holds it in the head.

List: I just installed a new oil pressure/temp gauge in the healey rebuild. 
Even though I have the backing nut firmly tight the sensor itself is still 
slightly loose, obviously, the best way to tell if it will leak is to fill the 
radiator but I am too much a coward to do it, I need someone to tell me that 
it is perfectly normal for the sensor to be loose or am I missing something??? 
Many thanks.
