The oil leak I have is coming out of the 2 small holes on the bottom of the fuel pump.

Your fuel pump needs rebuilding, that's all. There is an oil seal inside of it that surrounds the diaphragm operating rod, it has probably gotten hard and cracked or turned gummy and disintegrated. DO NOT try to just seal up the holes that the oil is leaking from, it won't work!

I have a 1947 Crosley Pickup that was my grandfathers that I am trying to get running for my grandmother's 85th birthday. However, I have some trouble with the fuel pump, I have installed a rebuild kit, but it still does not pump any gas. Would anyone have any ideas as to what I should do next?
Have you checked the fuel line? If it is the original blow it out. Also has your tank been cleaned? An original fuel tank that has not been boiled out can give you a lot of problems. I have rebuilt a couple of pumps, sometimes I have had to hook up the fuel line coming from the tank and work the pump by hand to get it to deliver fuel, before bolting it to the block.
May want to try a temporary tank , quart oil bottle rubber line , determine if it is the pump or the source. The pump can be operated by hand off the engine to determine if operational. I have had a problem with the pump priming on the engine but once the pump was hand operated and got gas to it, it worked fine.
Both of these suggestions are good. While checking your existing fuel lines, from the tank to the pump. Make very certain that there are no loose fittings or pin holes. On the inlet side of the pump, they will let the pump draw air rather than fuel and the pump won't prime. It may not show up as a fuel leak (if you ever do get it to prime and pump) as the air will just let the fuel drain back into the tank.
I have a 1950 Crosley CD that will not pump gas up to the carb. The rubber in the pump looks good and with it off you can make it pump, all the lines are cleaned out car will run with a gas bottle on top of carb.
You must have an air leak in the fuel system, possible fuel tank pickup is bad.
If you can make it run with the pump off the car but still connected to the lines, the fuel pick up is still a possibility. Fill your tank to the top to eliminate that. Then as Chuck has suggested check your lines as you could be drawing air. The pump moves faster on the car than by hand. You move that fuel pump arm farther by hand than it moves in the car. It is possible the pump arm has gotten bent or worn or the cam has worn in that area. I would put another pump on and try that first. A new pump can compensate for a lot of problems.
I repaired quite a few tanks where the pickup tube in the tank had a pinhole near where it is sweated into the fitting.
I'm solving my fuel pump problem by running an electric fuel pump. From what I've read and understand the Crosley engine fuel pump system is a 2 PSI out pressure and the 6 volt electric pump I bought is 8 PSI output pressure. So I bought a regulator to reduce the pressure at the carburetor to 2 PSI. It seems this should work. What do you all think? Now the next question. What controls the flow and pressure of an electric fuel pump. Does it run continuously but stop flowing when the 8 PSI is reached or does it cycle, start and stop? and if it starts and stops what causes it to do this? Another thing, I'm going to install a small surge tank made of 3/4" pipe between the pump and regulator to help eliminate pressure spikes from the pump. Does this make sense?
A regulator set at 2 pounds should work fine. The surge tank is not needed and maybe not desirable. Even though nothing is required to even out the pulses, in your case the regulator will do this. When the electric fuel pump reaches its "cutoff" pressure (in your case the regulator will cut it off" it will keep on running but just ceases pumping more fuel until the demand reduces the head pressure.
