Plumbing external pump over sump (versus drilling)

[gig]

so I am looking to get an external pressure pump for my Bullet skimmer (currently using a Mag24 in the sump, but the skimmer is outside the sump).

So I want to plumb this up and over, I'm sure others have done this (I've seen it done at my LFS), but what is the best design so that it's easy to prime the pump, anyone got pics?

Thanks!
