Fuel pump recommendation

I installed the rebuilt original engine in my Z28. Immediately the fuel pump had fuel pouring out of the vent hole. I installed a brand new from Napa and had flooding issues. Installed a fuel pressure gauge and 12.5psi.

I am looking for a replacement now and any recommendations would be appreciated.

Anyone have experience using a Carter M4685

Anyone have a Delco replacement

Anyone have an original 40669 rebuildable core.

Thanks in advance!
