Yes, looks OEM alright. EB seemed to have been phased out after 1969/70, I haven't seen any sources for it to date. I'm working on getting it and others properly reproduced but it's a challenge for sure and will be a while.

There are a lot of reproduction rubber hoses and lines out now (for most applications) that compared originals, aren't even close! It's an area of O.E. restoration detail that needs A LOT of improvement
