We used to use these as Intercooler Pumps for our s/c fords (aka coolest trucks ever).
Anyhow, I used to buy these in lots and this particular one snuck in, it's a 12-volt, High-Pressure 50% duty cycle pump.
You could mount this to your truck for transporting NSW, or use a 12v battery at home for pumping large volumes of NSW, RODI, etc. etc. etc...
Here's the owner's manual
This pump is brand new, never used, retails for $300-600.
I'm asking $200
