I my thread here, "What I Did on my Lunch Hour", I detailed the conversion of the OEM fuel pump to a "passthrough" so you can use an electric pump (I use Airtex) as the primary and not have to worry about the OEM pump failing and allowing fuel to get into the crankcase. I also install a "kill switch" to shut off the flow of fuel if it becomes necessary. I'm not a fan of combining the OEM with an electric pump as a primer. If you want to maintain the "stock" appearance under the hood, and eliminate any possibility of the OEM pump failing, this is the best way to do it, in my opinion. I have converted the OEM fuel pumps on all my Flatheads (6 & 12 volt).
