Mercedes G wagon power steering query

[chosenview]

Can someone who has done this please confirm that the hose from the PS pump feeds into the larger of the 2 ports on the MB steering box and the smaller of the 2 ports feeds back to the resevoir?

Here's some pics from a stock Gwagen that might be a great help!

Umm. That shows a low pressure pipe Into the bigger port and high pressure into the smaller one. So looks like I had it back to front. Thanks

As a secondary question

I'm useing a 300tdi engine to drive the pump. In the landrover discovery 1 there was no cooling for the power steering but when I look at the discovery 2 there is. Anyone with any views on the need to cool the fluid on the TGB?
