New fuel pump, no fuel pumping!

I just installed a new fuel pump on my 1962 Ford Falcon, and for some reason its not pulling fuel. Do you have to prime these fuel pumps? Does it just takes some time for it to draw fuel to the carb?
 
No need to prime it but you do need to make sure that there are no pinholes or leaks in the line to the tank where it could draw air, my car had sat for 10 yrs when I bought it and the rubber line between the steel line and the sending unit was rotted and drawing air. When was the car last run? You could have a plugged screen on the sending unit in the tank or a plugged filter between the pump and carb. And yes it does take a few minutes of cranking for the pump to pick up the fuel under the best of conditions. Good luck!
 
The same thing happened to me on the fairlane and it ended up being the screen on the pick up in the tank was corroded from sitting.
 
There is no tank in the car at the moment. I am awaiting my new fuel tank, and sending unit. At the moment there is a 1 gallon gas jug sitting on the floor with a fuel line going into it. I have all new rubber lines, and a new fuel filter. The fuel filter is the universal transparent Fram bought at all part stores. The metal fuel line is original though. The car has been sitting for at least 5 years. I'm not sure about the condition of the carburetor, but I figured I would at least see the clear fuel filter fill up with gasoline.

If you are expecting the clear filter to "fill up" you may be disappointed. I don't understand why but the clear filters often appear to have just a little in bottom but work fine...

I recommend the clear filters before and after the fuel pump, especially with unknown tanks.

be sure you have the right pump for your six, there are two different models, one short arm and one long arm.
 
Pump is installed right way up, correctly, and the two bolts are torqued to factory manual spec. My car came with a vacuum wiper setup, and there is only one kind of fuel pump for that. So I know that I have the right one. Maybe I just need to crank the engine some more?
 
Did you put a little fuel into he carb? I have always found I had to do this since the lines are all empty of fuel with the engine running you will get a lot more action at the pump.
 
You can put your finger over the hole and see if you get any pressure. Wouldn't be the first brand new pump that was defective. This was my first I6 fuel pump and was guilty of putting in on upside down, caught my mistake before cranking engine though. Everyone I ever put on had the outlets at the bottom instead of the top.
 
Put rubber intake line into your gas can totally immersed
Put rubber output line into a jar
If no gas is being pumped out, then:

1) bad fuel pump
2) lines are reversed(common mistake)
3) cam is not operating pump

I am hoping it is not the last one as that may indicate arm was not properly installed and is now broken off.
