In order to connect 3 inch engine pump and water absorbing hose, we purchased one-touch coupling. At first I connected Kakuichi GM 2 using the metal fittings of the home center, but the air leak did not stop and the water absorption failed. So I bought a product of Toyocs. There is also a drop price of plastic, but it was correct answer by choosing aluminum. I wrapped the seal tape and tightened it to the pump, and it was safe to tighten with a pipe wrench.
