Street 289: aluminum tube from expansion tank to water pump

[fintubi]

Hi, folks -

Heater-equipped 289 cars used a welded aluminum Y pipe to connect the McCord expansion tank and the heater return to the water pump. A reproduction of this is available.

Here's my question: what did *non-heater-equipped* street 289s use?

- the same Y pipe with the heater return capped?
- a pipe without the Y, just a simple ~90-degree sweep bend?
- all hose from the expansion tank to the water pump inlet?
- something else?

I'm currently using the third option - a hose all the way from the tank to the water pump - on my ERA slabside. It works fine, but if adding a pipe is correct, I'd like to do so.
