I would put a spare piece of fuel line on the pump output and test to see if you are getting good fuel volume out of the pump, if not, pull the pump and see what is going on.

If you have good volume from the pump, then move toward the filter and try there.

30 second volume is just over 1 qt.

It is possible you got a faulty pump, but I do not think I have ever heard of anyone getting a failure out of the box.
