Let me preface this by saying I’m relatively new to learning the ins and outs of an additional overflow tank, but I remember discussing this with Shane and Crash. It may have been on my thread or another one, I’d have to look back. They shared that the additional overflow tank should be clear and somewhere visible so you can actually see if it need draining. I think Crash even is using just a generic Dorman clear overflow tank. I also vaguely remember the conversation about it being higher so it can actually drain back. I could be wrong on this one, maybe they will chime in and refresh my memory.

I originally thought about a Motion Raceworks Black billet can as it would match my transaxle breather, but decided to hold off.
