The location for the sender or hydraulic feed fitting is the hydraulic distribution manifold.  Same place as the hydraulic pressure switch that controls the hydraulic pump relay.  My manifold is in the right hand main gear well.  I use the MVP-50 display to display hydraulic pressure, so I can't offer a gage type.

Any suggestions on which small hydraulic pressure gauge would be a good choice to display hydraulic pressure, either during preflight (ex, in wheel well) or inside the cockpit (for monitoring)?  Analogue or electric display?  Best location to T the gauge into the system?
Thanks.
