On the first one, you're looking at either a barometer or a pitot (sp?)
to determine either pressure or velocity.
On the second one, that's easy.
Find your sniffer tube, attach hose, and connect to a vaccuum/fuel
pressure guage. Read the pressure. Compare to a known good reference.
Alternatively, if you are working on a car which has no sniffer tube,
pull the oxygen sensor, make a hose fitting which will screw in, attach a
hose and do as above.
Any direct correspondence, please put my name in the subject line so I
don't miss it.
Please send any direct mail to my private address as I don't keep up with
the list very well.
