I.D. of turbo discharge hose 93' 6.5L

[84 C2B2]

Hi,

I'm going to clean up my father-in-law's oily turbo discharge hose on his 93' 6.5L TD. I want to either add constant torque clamps or T-Bolt clamps.

I need to know the I.D. of that hose since I'm 250 miles away and it's a birthday present for him. Any help would be great!

That hose requires sealant to prevent that problem. The GM stuff is nearly imposible to remove, but blue silicone has worked well for me.
