Hi.
Am after a 12V windshield washer pump that is self-priming; so if the reservoir is in a low place, will still suck and squirt. Any brand / model I should look at the wreck yard ?

 

You won't find a "Self-Priming" Pump on any Car or Truck.
That's why they are always installed at the bottom of the Fluid-Reservoir.

If you'll describe your project in some reasonable detail,
there are plenty of other options to choose from,
but most of them are not particularly cheap because of the required rubber-seals, diaphragms, etc.,
all of which wear-out over time.

Thanks.

I have 2 Cadillacs with no pump at the reservoir.

Yes, there is other choices am considering, but I have a wreck yard 2 blocks away. Every time I expose details of a project, get a dozen derailing proposals to do it different, none the way i want it, so now I expose the minimal pertinent information possible, be that right or wrong.

Everything wears out.

 

I consider a ~30+year life span to completely acceptable,
but something's going to deteriorate sooner or later.

Your Caddies must have been made before the ~'80's,
back when they used a Mechanical-Piston-Pump that was built into the WW-Motor,
I rebuilt a ton of them back in the day.
I guarantee the Pump is not mounted higher than the reservoir,
no matter where it might be located.
The newer-style independent Pumps are definitely not Self-Priming.

A "Self-Priming-Pump" is simply too expensive,
and too trouble-prone, for a WW-Pump application.

All Pumps perform better pushing rather than pulling.

Most of the guys here have multiple-decades of experience with what works,
and what will just be a problematic waste of Time and Money.
They also know a lot of tricks You may never have thought of.
Everybody has their own areas of expertise.
I'm very good at a lot of things, but I hang-out here just to see what more I can learn.

What are You trying to accomplish ?

How about a peristaltic pump such as this one.
As you do not give any flow rate or preassure information this is just a wild guess.

I'll second what LowQCab says... almost all pumps are built into the reservoir. I don't know of any remote ones other than the Caddie pump mentioned above.
