Can someone tell me what the p

Can someone tell me what the proper oil pressure should be on 1988 Crusader 454? Motors have about 1100hrs. Using straight 30weight Right now getting:

Port Starboard
700rpm 15-20 lbs 15-20 lbs
3000 rpm 30-40 lbs 40-45 lbs

Is the slight difference in the port something I should look into? or just a sign of age?

The gauges jump around a bit but I think is an electrical issue havent been able to track down.
Going to ry to get a mechanical guage on it. Does the guage just screw in wher ehte sender is? Thanks
