After getting 300 running again after sitting several months, oil pump does not seem to be pumping. How can I reprime it?
Thanks. I'll give it a shotRemove distributor
Remove oil pump drive shaft
5/16” hex rod in drill put it down the hole until it goes into the gear.
Turn on drill counterclockwise
if it’s making pressure it will slow down the drill some, depending on the drill.

A defective oil pressure sending will also give the appearance of no oil pressure.
Sometimes $.02 is all a man needs! Thanks. Any idea helps.If you don't want to pull the distributor and middle shaft to get to the hex into the oil pump, since the pump is external, you can unbolt it and fill it with petroleum jelly to help it pull prime.
Make sure there is as much oil in the filter as possible to make the delay shortest possible before it gets oil pressure.
To get the motor turning as fast as possible, pull out the spark plugs.

Another $.02...
The starting circuit is not designed for steady turning of an engine. It’s designed for bursts of high draw until the engine turns itself. By using the starter to try and prime it you risk electrical issues including burning out the starter or cables. Depending on the camshaft and length of time without oil you also may risk wiping out a lobe. Disregard if it’s a stock or high mileage deal.
There’s a reason for priming shafts.
