I ordered one and emailed them on February 19th. I'll let you know when I get mine.

this was the email I recieved back asking if they still made them.

"Yes we do still make these on a regular basis and I see your order. It’s currently in process"

Aluminum overflow tank
 

Yes,I’d be interested in one of those too,just waiting to get my syncrosaver sent first before an overflow tank.

Thank you, Hopefully you get it quick.

I have had this complete closed system kit from Pettit Racing since 2017 and love it, but it seems they are sold out of them.

​​​​​​​It's a great high quality unit, but the lack of internal baffles (like the stock unit has) means that you'll get a low coolant warning as the sensor coolant-starves under high G or elevation changes, since the coolant just sloshes around from one side to another.

how about now i still need to pick one up.. The fourm changed hands so i no longer get any emails when you reply.. TY

Found it as Spec B now.. Not sure what is missing from your Spec a setup..
But they seem to have it in stock.
