Self priming 2000gph??

Check valve near the tank intake would keep most of the pipe and the pump primed. I'd be more worried about diffusing the intake suction as it appears to be pretty exposed in tank and could do big damage to critters and pump if something gets sucked in. There needs to be some sort of prefilter or the pump needs to be able to handle debris.
Thanks, but I don't actually plan to simply have a 1 inch open ended pipe into the tank.
My issue presently is finding a pump that will work.
Inherent in your choice of pump is the consideration of the type of material it will pump. In your case, you have identified that you have the potential to being trying to pump two different materials (air and/or water), but you have said nothing about whether the pump needs to handle suspended material. Sumps are typically setup such that the pump gets particulate free water, I don't see a pre-filter in your sketch, which means that you need to take this into consideration when choosing your pump.
Perhaps if you give us more information on what you want the intake to look like we could clear this up and give you better counsel.
I was thinking this recently as well, the pump could suck in particulate. Not sure how else one could have an above tank sump though, it's been done though..
You are looking for a self priming pump.

I don't think a centrifugal self priming pump will work in the configuration you want because it will not provide a vacuum. Only a positive displacement self priming pump, like a piston pump, will provide the needed vacuum.
In my opinion... yes you need to drill a bulkhead to gravity feed water to your pump.

...Thanks for the link? but I'm aware a self priming pump is what is needed, which is why I asked, in the title for this thread, about one.. I don't need more info on how they work. Although some others on here don't seem to understand.
but from what I gathered, it's not an easy find, so Ive already drilled.
