Was this a new, used, or rebuilt pump? If it wasn’t new, than there is a gasket failed internally or components are misconfigured. There shouldn’t be fuel coming out of those holes. they need to be facing DOWN too.
Of course, I suppose a gasket could have failed on a new pump too. It’s just fiber material and the plastic diaphragm inside. Plus a couple of small springs with plastic cups to protect the gaskets/diaphragm. Don’t be afraid to pull it apart and rebuild it, just use the rebuild instructions.
