Fuel pump issues

1965 300.
So...the car would not start, no fuel to the carb, figured either pump or filter. Bought new pump and a new see through fuel filter. Removed the pump and the pump pushrod, measured 81.8mm or 3.22in or 3 2/9.

I have no idea on how long the pushrod needs to be or should be??

So put it back with the new pump and filter, no go, the pump does pump but wont fill the filter just a tad in the bottom. Just to try I disconnected the fuel line from the tank to the pump and attached a fuel...
