Skip,sorry so slow with a reply.By sight and not really knowing the correct terminology:-
The stock power steer pump has a "normal" High pressure hydrulic line [swaged?] going from the p.steer pump and a spring clamp line[low pressure]on the return to the pump.
The fan pump has spring clamp fittings both from the pump and on the return line although the outgoing line looks set up to take more pressure it is not a swaged fitting.
The info seems a little cloudy which is why I asked for more info but alas it has not been forthcoming.Will try a PM to Norbie.
Cheers.Pete.
