Any know the internal diameter for power steering hoses on the 535i?

I have a powersteering cooler that I will install on the car, removing the stock one. I need to add one as the front mount intercooler I have will interfere with it.

The cooler is 37x19x2 (cms) and uses a 11/32" hose. I picked it up from ebay, $35.

here is a picture >>

I need to connect this to the stock powersteering lines. I'll probably remove my fog lights and try and stick it on the front bumper down the bottom somewhere there.

Kris, 12x18mm are the hoses which go to the cooling coil

cooling of hydro steering, standard is the pipe/coil no. 1
