The washer I remember was commercial parts with a vinyl bag. The pump was a squirt plunger pump on the dash. It was/is brittle white plastic that was rather unreliable at the best of times. There were rubber hose(s?) from a clear bag hanging on two hook up front against an inside fender wall. Combining weak washer force, pathetic flow, and vacuum wipers is a very bad combination for a safe (and defensible) driving experience.

My suggestion is a small in-line 24v pump with a discrete dash panel flip switch.
