Oil Filter Leaking at First Prime of Oil Pump

bit more information. I have to purchase a new oil pressure gauge (current one isn't reading) so i don't have the pressure available. it is the stock style plate (not angled adapter) and i haven't pulled the plate off to confirm gasket yet (was fighting with it late last night and i didn't want to break it). its the same plate that was on prior to rebuild and i had no leaks at that time.
