I highly recommend pressure gauges for each circui= t in the panel or otherwise visible during all phases of flight.  It p= rovides all kinds of useful information.  It improves trouble shooting= and safety. 
=0A
For example, referri= ng to the test described below, without gauges one doesn't know why the pum= p did not chirp initially.  -pull the dump valve - try again.  If= the pump chirps, one can assume the system was pressurized and p= ulling the dump valve relieved the pressure.  Resetting the master the= n recharged the down circuit. 
=0A
Sce= nario 2:  If there is no chirp after resetting the dump valve.  H= mmm.  Is the system still pressurized (see Lorn's earlier post)? Is th= e pressure switch stuck?  Did the pump fail?  -bad solenoid = etc etc.
=0A
Having gauges on board also pro= vides useful data about impending failure, slow and developing leaks and an= y number of other ailments that might be cause for preventative maintenance= .

It is one of those mods that is worth it= s weight in gold.

I can support that test from Lorn. = ; At HPAT I learned the same test in the Legacy.  Normally, I hear a s= hort burst from the hydraulic pack when the MASTER is turned on.  If n= ot, perform the test below and it has worked in my aircraft.  That tip= came from the training session in Sebring recently.
