No offence taken, the lines were simply swapped from the original to the new in the same orientation. I am back on site so when I get home in a fortnight I will have another look. For example the low pressure lines are fitted at both ends with cable clamps and the high pressure lines had screwed fittings from memory. The new pump has a barbed fitting and a female screwed port - should be straight forward. I had run the car perhaps a klm without detrimental effect prior to this major failure, around local streets with lots of turns, would have thought it would have shown up is incorrect? Anyway, I will look at this when I get home. I just tried to find a power steering schatic for the TD42 power steering circuit - could not find one.
