I don't have huge metric wrenches here@ home, and my shop is locked up for the weekend. the fitting on the oil cooler itself is a hair bigger than 13/16 and the size of the line is a bit over 1" anyone know offhand? or care to go outside and look? by the way this is for the oil cooler that sits under the radiaror..

Thanks

For the stock SE lines it's a 22mm for the front and a 23mm for the rear.
