No Fuel??

[Born Lucky]

O.K. I just finished installing my engine. I installed new cam, new lifters. new
valve o-rings. I also cleaned all the carbon and installed all new gaskets.
I when to start the engine and found no fuel coming to the carb. I can tell because I also installed a glass fuel filter before the carb.
I used starting fluid and all I got was a loud pop(with some flames coming from the exhaust manifold)) but no fuel and no start.
The engine cranks nice and wants to start.
In the reassembly I thought I installed the fuel pump correctly. This is my first major engine job, so I could have installed it wrong.
Question 1 Can someone give me instructions as to install the fuel pump. I am going to pull it and I may purchase a new one since the old one appears to be original.
Question2 What is causing the loud pop?
