I ordered an adapter from http://www.rrproducts.com/default.aspx? for my jebao DC pump, but it has been more than a week and I have not heard anything other than an automated order acknowledgement...
I will be keeping an eye on this thread, as I created an adapter from a NPT fitting I had on hand and the union fitting included with the pump, by cutting and grinding down the NPT fitting. I did not take pictures, sorry.
