I have the same for Yamaha, didn't pay nearly as much.
The caps have been rolling around in a tool box for years now as I found them very difficult to use.
Mainly the height of the external tank is the issue. Too low and it won't siphon enough fuel. Too high and the siphon will push fuel past the gasket in the cap and cause a leak.
I also found the gasket material to be inferior, apparently not chemical resistant as gasoline caused one to partily melt and glue the cap on to my generator.
If I were inspired, I'd add an impulse pump like the Honda uses. No more need for a siphon, or use for the on board fuel tank.
If I had the need (I don't) that is what I'd do. You can get an impulse (crankcase differential) pump for about 20 bucks and any 4 stroke with a crankcase breather to air cleaner hose is a good candidate. That way, the height of the external tank don't really matter and the system is entirely closed and you can use the stock cap without modification Couple nylon Tee's, some fuel line and vacuum hose and you are golden.
