no fuel?

Not enough info... Did it run before and suddenly fail ?
Replaced everything else ?
It aint easy to bolt a pump on with the push rod out of place. It can be done but it will bend the pump arm or break an ear off the pump as the bolts draw it up tight.
The problem is either the pump itself, before the pump, or after the pump.
I'd start by attaching a rubber hose to the in side of the pump and dropped into a gas can. leave the out side of the pump disconnected and turn the engine over. If the pump works it will pull fuel from the can . Re attach the out side of the pump and the should run. If it dont run off the gas can the needle/seat in the carb bowl is stuck closed.
