Oil pump priming. Vaseline needed?

I was watching a youtube video from a guy who seems to know what he is doing. In it he cleans a new oil pump and packs it with vaseline to help the pump create suction and prevent cavitation when first installed. I had never seen this and wondered if this was good, bad, indifferent or even necessary? What do you think about this and his recommendations?

Why youtube ? Do you not have the service manuals/ performance books to build a performance engine.
IMO you are setting yourself for failure with the build if you are relying on YouTube.
Big block Mopar oil pump WILL prime 99.999 % of the time with oil in the filter and 99 % without oil in filter( not recommended)
