Looking thru classic parts catalog and I see there are two different oil pressure gage ranges for 1953. One gage has a max of 30 lbs and one has a max of 60 lbs. WHY TWO ?
My 53 1/2 ton original gage has a max of 30 lbs but I am using an under the dash aftermarket gage that shows I run an average of 30 lbs of oil pressure except at idle. So wouldent my original gage be pegged to the 30 side if I wanted to use my original gage ?
Doesent the oil pressure shown on the gages depend on the size of the oil line feeding the gage ?
