1986 Yamaha 90 hp feul problems

I have a 90 hp motor. I installed a new fuel pump, fuel line, tank, water separator/fuel filter, engine fuel filter. The problem I have is the motor starts fine. It starts to run out of fuel after a few minutes of running. I have to pump up the bulb to keep it running. It seems to be a carb problem or the fuel pump is not pumping, any ideas?

You may still have problem with fuel hose or fuel pump. Possible a loose fuel on fuel fitting, make sure all hose connections are tight or a bad fuel fitting like the quick disconnect on motor. Check fuel filter housing for cracks and make oring in fuel filter is good.
