Never heard that for any type of gear type impeller pump. I can see it being cool for a suction pump or if you only applied a heavy coat of lube but not a complete packing job. I would say especially so if there is less than 5 quarts of oil weight above the pump level. That oil weight creates an essential backpressure to force the assembly lube forward through the ports through the filter and into the galleys to the tappets and valves.

Really a thick assembly lube will create a gel like constriction on a paper/fiber media oil filter element and slow oil flow until it dissipates.
Packing the pump housing really won't do much anything for this type of submersion pump. If you can get it to flow through the pump it will only accumulate in the filter and create a restriction like above. Oil or a moderate coat of lube is best because after all the pump will be completley immersed.
