I just put in a new oil pump and was wondering if there is a way to prime it? Not looking like it, but is there a way to get some oil inside it while it is installed?
priming an oil pump?

Not really. I seem to recall when I installed my new engine I pulled the rocker arm cover off and filled the engine by pouring oil over the rockers and letting it flow down to the pan.
You can fill it full of assembly lube. Dumping oil over the rocker rails is also a good idea.

I installed it already without thinking. I know better but had football on the brain...
I'm not sure it will prime without some oil in it. I was thinking if I took off the balancer is there a way to get some oil inside the pump or should I just bite the bullet and remove the pump? In the old days we used Vaseline, but assembly lube is best.
You could try removing the pressure regulator, the hex plug to the left of the balancer. Pull the spring and plunger out, dribble some oil in there.

I just pulled the threaded plug that holds down the pressure relief spring out of the old pump and this looks like the way to go. The spring isn't so stiff that it becomes possible to cross thread the plug trying to re-install it. I should be able to remove it and get a small funnel into the opening which looks like any oil I pour in will coat the gears enough to create some initial suction.
Still can't believe I put that new pump in dry!

I actually played around with a spare pump for a few minutes this after noon. Yup the hex plug is easy to remove, pull out the spring, then you need a magnet to get the plunger out. Otherwise you're wasting your time.
When I started my engine up after sitting all winter, I first pulled all the plugs out, and squirted a teaspoon or so of fogging oil into each cylinder. Then I ran the starter and watched the mechanical oil pressure gauge, when it got up to about 50 psi, I put the plugs back in and fired it right up.
