it's from a GS450h. I made up a crude adapter plate from a piece of 1/2" aluminium and tapped three 1/4" bsp holes over the ports. This will allow me to use an external pump and run some more experiments.Best guess is left is the pressure port , right is return and bottom is a dipstick port. More to follow ...
