Please note - the regulator has been completely upgraded on the 252 pump and you may receive it when you buy this combo. The new regulator is the GR20 and comes standard with a pressure gauge, two discharge ball valves with ½" hose barbs and a ¾" bypass.  The old KIT1990 regulator has no gauge, a 5/8" bypass and one pressure line with no valve to control it. This is an upgrade we have asked the manufacturer to complete for decades and we hope you are as happy as we are!
