Having just put a new fuel pump and filter in my bus, I decided to have my
local mechanic check the fuel pressure for me.  His gauge read 39 psi with
the vacuum line connected and 45 psi with the vacuum line disconnected.  When
I got home and checked my Bentley manual, it said the pressure should be 29
psi and 36 psi respectively.  So, should I spend $50 and get a new pressure
regulator?  What would the extra 10 psi really affect?

Thanks,
