You would be about the 50 millionth hot rodder who re-used their old oil pump.
In all my experience, nobody has ever told me that they fragged an oil pump.

Find a container. Put a 4 liters of used oil in it. Sit the pump down in the container and have a buddy hold it in place so that the pickup screen in just slightly off the bottom of the container so that the pump does not suck itself down to the bottom of the container and shut off the intake of oil. (tilt the pickup cone so that it is not parallel with the bottom of the container). Find an old intermediate drive shaft that connects between the pump and the distributor and cut off the distributor connector, so that you have a driveshaft you can connect an electric drill motor to. Chuck the shortened drive shaft into your drill motor and fit the shaft down over the slotted drive of the pump. With the drill motor running clockwise as you are looking down on the pump, fire up the drill motor and pump the oil out of the container (you did remember to allow a place for the oil to go didn't you?) A 1/4 inch or 3/8 inch drill motor, at top speed, should empty the container in about 10 seconds. A 1/2 inch drill motor runs slower, but should empty the container in less than 15 seconds. If the pump won't do that, purchase a new pump.

I think the problem is that shipping costs to the OP's location will be much greater than the cost of the pump.

'49 Ford Coupe Even if you buy a new one, do the same thing. Take it apart and check everything.

chasracer For the few dollars a replacement costs, it's not worth damaging the other money (parts) that you have already put into the rebuild. I would let the rebuild sit until I saved the coin needed for the new pump rather than re-use a questionable pump.

'49 Ford Coupe Take it apart, look at the gears very closely, check the clearance of the gears to the cover plate, put a straight edge across the body and it should be about 5 thousandths..watch this video (he doesn't check clearance)
