The Moroso 20-tooth vacuum pump pulley is a purpose-built pump pulley specified by tooth count for vacuum pump drive applications. It helps maintain the intended pump speed and vacuum source operation when replacing a worn or damaged pulley. Fit it during pump maintenance or replacement to keep vacuum-assisted systems functioning predictably and to preserve accessory drive alignment on engines using dedicated vacuum pumps.
