PAS Switch/sensor - how much fluid does it lose?

[barker22]

Hi guys, just a quick one

Got a pas switch/sensor on the way.
How much fluid can i expect to lose when i unscrew it?
Not from a top up point of view, but I want to know if I need a massive container underneath haha

Cheers

A drop, depends how quick you are screwing the new one on.
