Coolant overflow tank question
 

I'm looking to replace my coolant overflow tank with an aftermarket one such as this: http://www.summitracing.com/parts/ZOP-6181/?rtype=10
So my question is, the OEM one on my 99 civic only has one hose, I'm assuming this hose brings in the coolant and pulls it out back to the radiator? Whereas the one shown has two nipples for coolant to go in and to go out.
Is there something im missing here? are the overflow tanks on the civics one sided?

It could be just a dump tube if the overflow tank is full from what I can see

from what i've read, the shorter line connects to the radiator and the longer line is for ventilation.

i recently picked up the Mr. Gasket 9133, but have yet to install it.

(will post an update once i do)
