Fuel pump issue

[The Worminator]

I got my engine all back together and now I have a fuel supply problem. Even with a new fuel pump, I have to constantly squeeze the ball to maintain fuel supply. Is this a carb issue? I replaced the exhaust skirt gasket and It runs beautifully otherwise. Those obviously shrink when they dry out with age.

Check the hose for leaks.----Check pick up tube INSIDE the fuel tank for leaks.-----Fuel pump is drive by crankcase pressure pulses.----Check for issues there.-----Picked up 5 of these 9.5 HP motors in the last 2 weeks for parts / repair.----Great , light weight motors.

I’m at a loss. When I started today, the primer ball would get rock solid, and it would run for about 3 minutes and then air would start appearing between the fuel pump and carb and it dies. Then the ball wouldn’t get hard anymore, so I got a new one, and it still would not get hard priming. I also thread taped the connector at the fuel tank. Now it won’t even push fuel to the carb, and there is no fuel leaking anywhere. If I were to place the supply line directly in a fuel container, should it run??? I’m just trying to rule out a bad tank. I had no issue with the tank before. I also am wondering about the pulses that run the fuel pump.
