Thanks for asking your question. I will try and help you out.
Many times to prime the system, it best to disconnect the fuel line that runs from the back of the head and goes to the filter housing. Then operate the hand primer. It should be easy to clear the air out. The fuel pressure regulator is in the filter housing. By disconnecting the line at the housing. It makes it easier to operate the hand primer and get the air out.
