I made a pressure canister out of an old fire extinguesure about 50 years ago. I welded a metal valve stem into the side & hooked a hose in the outlet. I put oil in the cannister & air pressure in the tire valve. I use the gauge to know how much pressure is in it. I remove the oil pressure sensor from the engine & put the hose in it with pipe fittings. Pull the trigger &when the system is full the gauge will drop slowly.
This also works well to diagnose low oil pressure. Remove the pan & apply pressure & watch for heavy flow.
