Hey, that helps.  I used that logic to check the wiring.  Result is: back
to the initial theory that I have a wire shorting.
-when I disconnect the HP sender at speed > 2300rpm, I get a BUZZER.
-IE, buzzer is NOT broken.
-IE, my challenges are limited to LP sender, and NOT the actual pressure,
because I never had the buzzer sound when the light was coming on.

Took the tin off the left side of the engine and found the LP switch
insulation is damaged.  Cleaned-off the gunk and taped that up for
troubleshooting.
-marked the tin so that I know where to trim it so I can install a pressure
gauge.

Any recommendations as to the pressure gauge?  I see that VAN CAFE has a
nifty kit:

Anyone have any comments on that?
