When I plumbed my aux water tank to a 4.5 gpm 65 psi marine pump, I originally used a 1/2" right angle hose bib. It didn't supply enough water to the pump and there was considerable cavitation on the impeller. I upgraded to a straight 3/4" boiler drain valve and that solved the issue and improved the discharge.
A budget hose Bibb might have had an orafice of 1/4”. A full bore ball valve would have been a better choice.
