  The one on the head is low pressure, low rpm.  It's something around 4psi
and is "looked at" below ~2000 rpm.  The one on the filter housing is around
20psi and is read above ~2000rpm.  Thus the use of the W terminal on the
alternator, to indicate rpm.  There are a few different senders between the
gas and diesel engines so be sure to get the correct one.
