City water

I see i quoted wingnut60 in error and was addressing JonnyB question.
No GearHeadOSU I do not ha e any idea what Jonny B has and looking at photos of 1998 Aljos did no show enough to ID what they did in 98. He is asking if anyone knows where a valve to toggle from tank to plumbing is so I am only ASSUMING the is not any seperate tank fill port.
If a fresh water tank is filled from SAME hose connection as the ciry water hookup there is a valve to direct water into tank. Or there has to be a seperate fill for tank. This port could be another hose connection fitting or often was a larger port with a cap that you simply poured water into with a hose or jug.
I hope he has found it or he must be pumping from his tank.
