Subject:      Checking Pressure Regulator
Content-type: text/plain; charset=us-ascii

Hi List,

Tonight I was checking the pressure regulator in my 87 Syncro, and had a
question regarding the residual pressure.  My pressure checked almost
perfect at idle, and held between 28 and 30 for the ten minutes required
(page 24.55) after shutting off the engine.  As silly as this may sound, I
wasnt sure if I should disconnect  the vaccuum hose while checking the
residual pressure.  Im pretty sure I wasnt supposed to, but Bently showed
the pressure should be between 29 and 36psi, the latter being the value for
when the hose is disconnected.

I disconnected the vaccuum hose anyway and saw no change in pressure.  For
laughs I clamped the return line to the fuel tank and nothing changed.  I
then clamped both hoses leading to the injectors and the pressure jumped up
to about 34/35.  When I disconnected the clamps, the pressure dropped down
to about 20psi.

Im assuming everything checked out ok, but could some reassurance.

Thanks,

Jeff
