I have a similar set up on my fiver . I have no gravity fill inlet.
However I have a setting in my convenience center that will allow the on board pump to suck water via a container or bucket . IOt is a simple matter of attaching a hose and putting the fill switches in the correct position. No big deal.
If you look closely those 3 flip switches at the bottom control the fill. At the bottom left os a port to attach a clear 1/2" hose that will suck water from a bucket via the onboard pump.
The set up is quite ingenious and beats hoisting 5 gallon jugs to fill from gravity fill inlet.

I am a gadget guy and I have to say that's an impressive "Mission Control" panel! :)
