I make one inch pipe to AN adaptors to convert the thermostat  and water pump.  The thermostat adaptor comes in two versions, one if you are using a thermostat and one if you are not.  You can view them on my web site www.j-winddesigns.com  The thermostat adaptor also lowers the outlet a couple of precious inches.   You will also need same fittings on the swirl  pot.    Jerry
