Thanks for the explanation....I like your McGyver-ing to get it to work....still wondering though if the threads are the same on the Tsunami inlet as on a typical Rule inlet.
Here is a picture of what I mean. Are the threads circled in red on the two different pumps the same??
I'm not actually going to be using a Tsunami pump; rather a fitting that I know fits a Tsunami but I need to find out if a Rule fits the same.
