Jimmy825 Posted July 24, 2022 Share Posted July 24, 2022 (edited) Purchased a new pump and the old one has a breather in the hub. The new one does not even have a threaded hole for the breather. Is the breather needed and should I just return to Mack and see if it is the correct pump to use without the breather Edited July 25, 2022 by Jimmy825 Misspelled word Quote Link to comment https://www.bigmacktrucks.com/topic/70170-water-pump-replacement/ Share on other sites More sharing options...
