don't trust a DC motor. it might spin with no load, but it will fail to work as soon as you present it with any kind of load. Maybe the brushes wore out from running continuously due to vacuum leak. That GM HD truck pump seems like the best option unless you can get the orig LT5 unit from somebody else more quickly (and cheaper).
