City water hookup

I bought a new camper in 1977 that had a "bicycle" pump inside. If you filled the tank with a connection to city water the tank was automatically pressurized and only a little pumping was needed when the tank got low.

The OP lists a 1985 Coleman Sun Valley in his profile. Maybe that's it?
It looks like it's something from the 1950's.

You had a compressor? We had a bicycle pump

I had a camper once that used air pressure to move the water. You filled the tank with water and a onboard compressor put air pressure in the tank to move the water around, when pressure got low, the compressor came on and pressurized the tank.

Before water pumps you put your water in and then pressurized to force water to flow.

Interesting.

Looks like a combo city water inlet and air connection with built in pressure gauge
