I want to set up a small pump to run a little oil where the blade is cutting to help keep the blade cool on our harbor freight metal band saw (which is awesome). Any ideas? Doesn't have to be very high volume, or much pressure, and I'm using used motor oil, so it might be a bit dirty... Maybe a windshield washer pump? But I would like 110v, so I can plug it in.

I don't have any idea of a pump, but growing up working in an aluminum fab shop we used a dishwasher detergent solution and compressed air kinda like a paint sprayer.
It will go everywhere and detergent is already halfway there to being cleaned up. Can you imagine oil all over everything? YIKES!
Why a pump. Use gravity.

Yes gravity! Hang a largish bottle of fluid over the blade and allow just enough drip to cool the blade.. I did it with my cheap band saw and the blades really last..
Just buy a bottle of RapidTap and put a few drops of it on the cut line. Done.
It's all we use at work, no mess, no splatter and no funky-smelling vat of soluble oil after a few months.
We only go through a pint of the stuff every year or so and we have a lathe, mill, drill press, bandsaw and mechanics who need to use taps a lot.
It doesn't cool BUT it makes the blade work so nice that you don't really need coolant.
