Hi All,
Yes, the “S” shaped hose is unique to the Jetfire and the “J” hose is common to all 215’s. The 2 & 4 bbl cars “S” hose looks similar but has one leg long enough to reach all the way to the water pump, all as one piece.
All the Jetfire coolant transfer tubes that I have seen/used are straight with “bumps” on both ends to help seal the hose on the pipe. Pic’s attached. Coolant transfer pipe along side of valve cover.
