I have seen a few references that suggest metered fuel pressure is
what TCM recommends/assumes.  I may be reading more into this than is
intended.  TCM IO-550 maintenance manual 22-3 in talking about tool
requirement for fuel setup and I think this is in SID97 as well, talk
about 1 calibrated 0-30 psi gauge  for measuring metered fuel pressure
and verification of aircraft fuel flow gauge indications.  In the
flight test section it goes over normal values for fuel flow and
metered fuel pressure for altitude not unmetered.

I am not sure I have ever seen a statement for TCM that metered is the
correct way to monitor fuel pressure, so I should probably retract
that statement.
