O-Ring Size

Hi all - new to the board. This is a great refernece site for Mark VII's!

A few co-workers and I recently bought an '86 Mark VII to run in the 24 Hours of Lemons and ChumpCar series races. Sa far we have run one race and are getting ready to run it again in about 3 weeks. The car had a major power steering leak so I just replaced the rack. Of course the rack came with the teflon seals for the lines but it did not come with replacement o-rings for the type-1 and type-2 fittings on either end of the high pressure line. I'm still getting a leak on the high pressure line at the pump. My question is - does anyone know what size o-ring is needed for this fitting. I know it is either a 5/16" or 3/8" ID but I'm not sure about the width.
