Regardless of what fittings the pump and box utilize, Borgeson has a method for connecting the two (at least non-weirdo applications) via brass ferrules that convert O-ring style ports to metric or standard flare, depending on the application. Part number 925103 would have worked perfectly for us, but both lines were a little bit short and the pressure line fitting didn’t clear the grille. In a time crunch, we ended up ordering a stock replacement pressure line (Parts Master PN 91453), which was less than $25 at our local parts store. We did use the Borgeson return line with a short extension, since it is low pressure. Borgeson can work with custom applications; we just ran out of time.
