Happily,
Yep. The Yellow bits and associated tubing permanently replace the original battery caps. There's a one-way valve on the end of the fill hose that plugs into the pump when you need to add water. The tubing is flexible enough that freezing isn't an issue.
I'll have to remove the forward coach battery to add water or install the Pro-Fill. Once installed I can slide the battery back in and will be able to easily top it up.
