Maranzano had nothing to do with Fanucci: the latter was a freelance collector. It's revealed pretty clearly by the novel.
Also, running to Abandando's home would be the worst young Vito could choose, as they'd be immediately suspected. He had to hide somewhere else; otherwise there'd be no Godfather, believe me.
Best regards.
