    It looks like a 3/8″ hose and mine has reusable ends. I’ll be using Eaton/Weatherhead H06906 and I’m in the process of replacing several of mine. Most bigger hoses are 2.5″, 2.75″, and the ones on the transmission cooler is 3.12″. These hoses seem to be in short supply as I’ve had problems finding them in Houston for my business. I’ll give you a call.
