I am with Ken on using the 80 PSIG sender. I have an 0 to 80 analog gauge
in my MAC dash. On a cold startup it indicated 65 psig and settles at
about 48 psig at run temp. The stock Oil Pressure Indication in the dash
doesn't know if it is 60 or 80 Psig, as it is a 0 to 90 ohm sender. You
have to interpolate what your gauge means. The 60 psig sender is 0/15/30
at midpoint/45 and 60psig at 100 %. The 80 psig sender is 0/20/40 at
midpoint/60 and then 80 at 100%. I too like to see all my important
gauges, oil and water temp to be pointing at midpoint.
