Want to run a new hose and didn't drive the car today so I can't see what size is on it . Have them capped right now and one is starting to leak so going to route a hose now . Thanks guys

 

3/8", 10mm or 06an hose is the correct size for both

 

Thanks man I did end up find a prefect hose for the job . At least to run it under a t2 intake any . The part number for the hose is gates 18321. It has all the right 90's to clear everything and a long stretch to run under the upper intake by the rails . Cut of the last bit that was a 45 degree . So to do a coolant bypass use this hose . Hope that helps some one else . And DO not cap the ports they will pop and crack .
