Answer
I think the pump is sucking air. Did you fill the tank, or just put a little in it?
I assume the pump is in the tank. If not, I would sure check the connections on the tank side of the pump for leaks.
If the pump is in the tank, I think I might pull it back out, and see if the pump sits in a container inside the tank that keeps fuel from freely getting to it. If so, there is a return line, and it needs to return the fuel INTO that container.
But for some reason, the pump is starving for gas.
Good luck,
Van
