I want to install a capillary gauge to my Mini and have this (see attached photo) fitting from mini spares which sits on the heater valve position. I think this is 5/8 UNF so its the same as the engine block original sender's positions.
Anyone know a reliable capillary gauge with 5/8 UNF threads that attached to this fitting?
p.s. The reason I am not installing it in the original block position is because i have A/C and the alternator is very close to the sender unit (which will be too close to the capillary tube and may damage it !)
