I (believe) I need to replace the rear washer pump. It doesn't make an audible sound when activated and of course it doesn't squirt any washer fluid. However I cannot find:

1) a diagram that matches the tank and pump configuration for what I see on my car—what I can see is a single pump on the bottom of the washer reservoir. What I've read indicates there are at least two pumps—one for the windshield and headlights, and a second for the rear window.

2) The correct pump part number. The replacement pump I have doesn't match what I've seen on the diagrams. Mine has two small hose nipples (see attached image of pump) while what I've found online shows a pump with a small hose nipple and a large tank nipple.

Am I missing something?

Documentation online is scarce. Any help/instructions are much appreciated.

Thanks!
