Ray - This was my first posting to the LML and am glad to receive comments.
They help to fix problems or confirm a workable setup.

Randy and Chris - I believe your questions and comments are addressed here
also.

The Aeroquip fittings that support the sending unit and inline filter on the
pressure side of the system are secured to the mounting board which
eliminates any structural load on the hoses.  I am using aircraft quality
hose and the clamps are safety wired.

The fuel pumps are individually controlled and are wired back to the buss.
They don't even share a ground wire :-)  I can operate them one at a time or
simultaneously.  The fuel injection system is multi-port.  The pumps
maintain a continuous flow through the fuel rails and back to the header
tank.  When the engine is not running the system pressure is approximately
40 PSI.  Once the engine is started the pressure in the rails is controlled
by the engine fuel pressure regulator.  The pressure sending unit is located
at the supply (inlet) of the system.  The MAP is picked up by the regulator
located at the end of the system.  I do not have an engine driven fuel pump.

My Andair gascolator is installed at the low point, low pressure, inlet side
of the system.  The inline filter (visible in the pictures I posted) is
probably overkill and any water that may have gotten into the header tank
should be removed by the gascolator before the fuel reaches the pumps then
to this filter.  My intention is to remove this inline filter for cleaning
during scheduled maintenance.  At one time I was planning to install an
additional inline filter between the header tank and the gascolator, but
have opted to not because I would not know if it trapped water (without
removing it) and my expectation is that the gascolator will perform that
function.

Again - thanks for the comments/questions.....
