How do you prime the oil pump?

Just throwin this out there. I've actually seen assembly lube keep an oil pump from pumping. It was not on a Gen3 Hemi, but a small block. It was an HV pump, too. I never wouldda guessed that'd happen, but it did. Maybe the Gen3 Hemi pumps are made in such a way that won't happen. It sure did on a small block, though.
