Greetings.

Well my experiment with the vacum gauge connected before the check valve
was a failure. The gauge readings were not matching the descriptions as
per the manual, nor did they match the readings from a previous post I
read. Tonight I changed the tee connection to the vacum line at the
pressure regulator and voila ! The needle moves nicely with the engine
rpm's and reflect the instruction booklets description of the readings.
Didn't have time to do a test drive tonight, but going to the mainland
tomorrow. Got to get some sleep, have to be up at 4:30 AM to catch the
first sailing. Good night.
