Ian, yours looks like mine . It has a three out let 1'' BSP fitting on top of the pump . I fitted a I'' nut and three quarter tail and hose to suit. For nozzles I just turned up a couple of plain brass ones ,with a not adjustable 1/2 bore .'' You could use a couple of those 1/2 '' adjustable brass ones [ Bunnings], that way you can shut it off at the nozzle.................suction is 1'' ,with a foot valve . Even though there is a rubber flap valve in the pump body I found the additional foot valve worked much better [easier priming].
