Without knowing how your filter is plumbed into the oil circuit now I cannot offer actual suggestions. Just be careful on removal to not cut off the oil flow to the valve lifter gallery as has been done on some engines when people simply removed the filter and replaced line connections with plugs in the newly opened ports.
Make sure there is a connection between the two ports on the drivers side where the filter would normally tie in. The bottom port where the sender attaches is the pump output and when the filter is removed oil flow must be established into the upper port which feeds the lifter gallery. On engines without filters or those with partial bypass this is done with a curved jumper or pigtail tube connecting the two ports. When some filters are installed the jumper was removed and oil flows thru the filter first before going to the upper port to feed the lifter gallery.
If yours is some version of this configuration the jumper must be replaced when you remove the filter. If the filter is a later bypass version with return oil dropping directly into the crankcase via a port low on the block just above the oil pan then you can just plug the old filter supply port on the tee in the lower hole and put a plug in the crankcase port.
Here is a drawing showing how some filters before 51 were installed. This configuration needs the jumper (4) re-installed if the filter is removed.

will run without a filter for now
