More Washer Pump Questions

[Stormhawk]

Gents,
I need to find a cost effective fix for my washer pump.
Truck is an '83 K20 with the multi speed wiper switch on the dash.
The wipers work great, but my washer fluid pump doesn't pump.
I've seen replacement units that replace both the wiper motor and washer pump, but I need to fix this on the cheap.
I'm not concerned about originality, just functionality. Can I wire in a new pump between the fluid reservoir and the sprayers using the existing switch?
I've seen simple pumps like the one in the link below that look like they'd work?
Any ideas?

using the existing switch

You should be able to- WHT 93 wire will brings 12 volts from the fuse box. PNK 94 goes back to the switch where it is grounded. Same wire setup on 85 & newer except the wires just goes to a separate pump (like the one in your link).

You can buy the newer reservoir and pump, ideally with check valve too, and install it where it goes on the newer trucks im pretty sure you also bump capacity a small bit.
