I think I would rather cut my losses and look for something better, like a proper used EV vacuum pump.

EDIT: I went to the hardware store today and picked up a 12V air compressor on sale. I got home and took it apart. Aaaaaaannnnddd....it won't work. The pump does not have a an intake port - the crankcase is open and the inlet valve is built into the piston. I was able to reverse the position of the inlet valve, but not the outlet valve. I reassembled it and made sure it still works and I will return it one of these days.

Scratch that idea. I am now searching eBay for real vacuum pumps.$$$

This is what I would use if I needed a pump.

Amazon.com: Dorman 904-214 Mechanical Vacuum Pump for Ford Truck: Automotive

Its a replacement for the diesel ford trucks.

My Corvette has manual brakes already, so I didn't have to worry about vacuum issues.
