Overflow Question

I have one of these. The question is, how would I plumb it ? I have one hose/tube coming from under the radiator cap to my current overflow bottle. This one has a second tube outlet/inlet. There is an internal tube running from the bottom to the top from one of the inlets.

I just installed one of a similar design. I plumbed the radiator to the port without the internal tube. The second port is for relief if the level gets to high in the reservoir. I will know how well it works next week.

 

i assume it mounts with the fittings down?
Then the hose from the rad cap goes to the one without the tube.

 

Correct, the fittings down. So, what are you doing for the second outlet ?

 

NICE! way better looking than the cheapy kragen junk in mine....
