Electrical: Avanti electric washer system

[jerry1]

I am working on the windshield washer system I noticed I have a electric switch under the dash. There is a wire going to a bracket. I know I need a washer bag but what type of electric pump do I need. Thank for help..

What year Avanti? Originally there was a foot operated pump located above the dimmer switch. There was no electric pump involved. There was also a switch mounted on the foot pump that activated the wipers (hands free)! Some later Studes have the same setup.
The foot pump is a rubber bellows that expells washer fluid when stepped on, and draws it in when "relaxed". The washer bag has a one way check valve built into the cap.
The larger hose goes to the foot pump, and the smaller hose goes to the nozzle in the cowl.

I have a 1963 Avanti. There is a push button under the dash with wires going to the wiper bracket.

You can rig up a non-stock pump motor quite easily. Power from the push button to the motor(be sure and ground the motor). The larger nipple on the bag to the pump, and the smaller hoe nipple is now capped off, and the hose from the squirter now goes to the pump.
Most parts stores will stock a generic pump
