Yes H2, the Honda does require the adapter. Because it is flat metal to flat metal, there has to be a washer of some sort between the valve and adapter. I thought the blue washer they supplied would be okay for that application but I did not think it would be suitable for the adapter to pan connection. I may just use a metal one between adapter and valve too.
And thanks for the tip on keeping the valve open for a while at first - it is pretty hard to open now even when I am holding it in both hands. I can imagine the problem if it gets positioned in a bad location and I can only get a finger in there.
