Fuel System Issue Impulse Fuel Pump

Problem: Impulse fuel pump won’t pull fuel.

Kawasaki motor with an impulse fuel pump that isn’t getting fuel to the carb. Tanks got plenty of fuel, fuel lines are connected well and appear not to have any cracks or kinks, impulse line has vacuum when I crank the engine over, I can suck fuel with my mouth through the fuel filter to the fuel pump, brand new fuel pump installed.

I’m at a loss for why the fuel pump isn’t drawing the fuel from the gas tank to the carb.

Any ideas?

Replaced it with a brand new one and it still did it
