John,
I certainly don't disagree that measuring everything that you can, has an
advantage.  Since I change my primary fuel filter each year during the
conditional inspection, and the filter on my secondary pump, every other
year, I haven't had an issue with a plugged filter.  But none the less, I
would like to know what it is.  It's just a matter of priorities at the
moment.

As far as a set of injectors not powered, I would certainly think that would
cause a real performance issue on full power.

Steve & Others,
We all set up our engines in such a way that makes us feel secure, and
no criticism intended, but I wanted to emphasize a couple of points for
other readers....
You mentioned that you don't switch the injectors separately. Switching
off one set of injectors is a standard part of my preflight, and it has
saved me from taking off with one circuit down. Also you said that you
have no fuel pressure gauge on the panel. The fuel pressure reading on
each pump is also part of my pre-flight. During the first few hours this
helped me detect a blocked filter and a bad pump ground, and once helped
me solve rough running in the air.

Extra switches and dials in the cockpit certainly increase pilot
workload, but they sure help with problem diagnosis prior to and during
flight.
