Some fuel systems have a filter before and after the pump. Some with one filter usually have the filter after the pump. I would verify that the pump is installed right, then I would take the outlet hose off of the pump and put a short hose on it, stick the hose in a jug or something to catch the fuel and run the pump. Here is a link to a typical fuel system if it works.
