I had a 1006 years ago that had a city connection and a water pump built into the handle. If that is the same as yours than you might be able to add a 12 volt pump in the line that would work.
You will need a pump, backflow valve, possible a strainer/filter, switch, wire and fuse holder and fuse. Maybe a $100?
Mine had a very small tank, maybe less than 10 gallons. With that you could go though it is a heartbeat. Especially if have kids. Handy for washing off babies though.
