65 dart 273, No fuel from pump to carb!

If no fuel going to carb, its most likely Fuel pump.

Any fuel at out port of fuel filter?

If yes?

Try putting a little gas directly into carb? Make sure the throttle blades are open when you do this.

This effectively bypasses the carb as you are putting gas directly into intake manifold.

If the car tries to start or starts briefly and shuts off problem is Carb related as long as there is fuel in the fuel line going into the carb.
With the gas can method, still not getting fuel to any of the lines or filter so I think it’s just a bad “new” fuel pump. When I tested the pump itself, I did feel blowing on the outlet and sucking on the inlet so I’m not sure if it’s just not doing it well enough. Like Prof. Fate said, I put fuel into the bowl vents so it should have fuel in their regardless but still not firing up so I may have to pull it off and do what you mentions. I’m not too familiar with carbs so I will have to watch some videos or wait for reply’s
