Tabe,

Here my story:

This past summer, my van smelled like it was running a little fat.  About
that time I read the words of wisdom regarding fuel pressure regulators from one
of our many resident experts.  He said the fuel pressure should be 29/36 psi
spot on; anything else was unacceptable and demanded that the fuel pressure
regulator be changed.  When I checked the fuel pressure of my van, I found it to
be 32/38 psi.  I changed it out for a used one I had and I found the pressure
to be very nearly the same.

The gauge I used was of industrial quality (USG) but to make sure, I checked
it against a very high quality gauge which had been calibrated at some point
in its existence.  At 20 through 50 psi they were in exact agreement.  Wanting
to obey the Voice of God, I bought a new fuel pressure regulator.  Well,
surprise, surprise.  When I checked the new regulator it showed 32/38 psi.

The specs for the fuel pressure regulator per the Bentley call for
APPROXIMATELY 29/36 psi.  Is it reasonable to say that APPROXIMATELY means +/- 10%?  So,
26-32/32-40 should be APPROXIMATE enough.  I think that if the fuel pressure
regulator is queefed out, most likely it will show a high pressure which does
not change with the application of the vacuum.

So, validate your gauge and save your money.
