Did what I needed

March 21, 2016
Tank was great and matched what was advertised. The bottom fitting was only hand tight and sealed with pipe dope. I changed that before installing but I think it would have leaked. Would buy again.
Yes, I recommend this product.

Is there a way to get this with -12 AN fittings or barbs? I would like a tank like this with larger fittings.

Sorry I do not have the correct fitting to adapt this to AN12. The tank is threaded M24 x 1.50. You would need a fitting with that thread on one side and AN12 on the other side to get the bottom to AN12. The AN6 bung on the side of the tank is welded on. If you want that to be AN12 you would have to weld on a different bung.

Routing of the 3 fittings on this tank??? This tank has 3 fittings on it. The one on top that probably routs to the radiator's overflow outlet by the radiator cap. Where does the AN fittings that are located on the top and middle route to? Also what benifits are there for the middle and lower fittings? I'm using this on a build that has a LS1 motor. I was just going to use te upper fitting but might use all 3 if it is needed.

This is a true expansion tank, not an overflow tank like I believe you are after. This tank is used when you do not have a radiator cap on the radiator because it is mounted lower than the engine. You will route a hose from the bottom of this tank to the suction side of the water pump, then a hose from the -6 fitting on the side of this tank to the low pressure side of the radiator (where a radiator cap is typically located). The top fitting is simply an overflow hose connection that can be routed to the ground or a separate catch can or overflow tank. If you are after an overflow tank we offer those such as 91102213. That tank will simply have a hose connected from the overflow outlet at your radiator cap to the short tube on the bottom of the tank. You can connect a hose to the long tube on the tank and run it toward the ground in case this tank gets filled up by the radiator venting fluid it will then be pushed out of that longer tube. The terminology of expansion tank, overflow tank, and recovery tank is sometimes used too liberally. They can be separated into two categories - one that has a radiator cap on the tank, and the other that does not have a radiator cap on the tank. If the tank has a radiator cap it must have hoses routed as I described to the water pump and radiator. If it does not have a radiator cap then it is intended to be a simple "overflow tank" or "catch can" which simply catches the overflow of coolant that the radiator cap allows to vent out.

This tank can be mount to any tube in car and should be mounted even or above radiator. You can plumb into fittings in manifold or install part #91717627 into return radiator hose. If using with radiator that has cap plug off overflow tube on radiator
