Question on my oil pressure readings-happy father's day

Dude. Fix the dang leak before you make a decision. That might make a big difference. It is in a main pressure port.
It's in the port by the distributor but I tightened it slightly while it was running yeaterday just to see and it stopped, not sure if it needs to be tightened more and it's a stainless steel -4 an line. Saw maybe a 2psi pressure difference but maybe needs to be tightened more. I'll be able to do more work on Wednesday
