Are they a way to test the oil pump if I remove it from the block?

Search back a few years ago, I did a long post on how to make an oil
pump tester out of plastic tubing. The plastic is a tight fit on oil
pump. You remove the drive gear and turn the pump with a 1/2" electric
drill. Run the drill in the same direction as drilling a hole. Put a flexible
plastic hose from the pump output to a 100lb oil gauge and another hose
after the gauge. Put the pick up screen of the pump down in a pan of oil.
Turn the drill on, when oil starts to flow bend the hose after the gauge.
the tighter the bend it the higher the pressure. Let the oil go back into the
pan. You should see over a 100 lbs. The pump may have an internal
pressure by pass valve that is leaking. The gears could also be warn
or the gasket on the plate on the bottom leaking. G.M.
