If DD shops are using a drill connected to the generator line, why couldn't a small pump be connected in that line to do the same. A normally open solenoid could be in parallel to allow oil to always flow straight through except when the pump is engaged. This would only require a pump, switch, solenoid and connectors for a manual system. I don't see why a simple pump such as this one wouldn't work. http://cgi.ebay.com/ebaymotors/Biodi...ssoriesQ5fGear
