Oil Pressure Switch

A new oil pressure switch arrived this morning.   I had already decided to future-proof the system and bought one of these:
 
It's a 3 way system, so you screw it into the engine where the old sensor went and then you can screw in the new sensor and also you can screw in a separate oil pressure sending unit for when I get a standalone Oil Pressure Gauge.  
 
So the picture on the left shows the old sensor simply screwed in.   The picture on the right shows the new unit screwed in and the new sensor screwed in the side hole.
 
 
 To stop oil gushing out I have temporarily screwed the old broken sensor in the top hole until I get the sender.  Interestingly, all the threads are tapered to make a good fit when lightly tightened.  It was designed so you didn't have to use PTFE tape.    But the new unit recommended you still use PTFE tape, so I did.   Result:  Works perfectly, light works as expected and no leak.
