Do I NEED to prime it?

Okay let's get this 100% clear that using a priming tool will clearly pump oil through channels. Did the pump loses Prime? Will it take awhile for the pump to even get it sucked up to the tube through the well filter and down through your places? I 100% disagree was spinning the motor without oil have that has been previously pumped through it. Anybody will tell you 99% of engine where is on at startup? What the hell are you thinking...
I'll drive up to my local parts store and take a picture of one and be back here or up there posting it within 10 minutes. On a bet. I actually used it on my buddies 403 Oldsmobile motor in his Trans Am when we broke it in.
