just bought '76 toyota chinook. great condition. need to know how to prime water reservior to use kitchen sink. don't have manual. doesn't seem to be any clogs or such. there is only a back and forth lever, no motorized parts.
Hi Carrie and welcome to the RVUSA Forum. That back and forth lever is the water pump and after 35 years, it's probably shot. Camping World has one in their catalogue for $30.00 that might replace what you have - either that or get a small 12 volt pump and standard faucet to replace your old one.
