ABSTRACT:
An auxiliary electrical oil pumping and draining system for internal-combustion engines operating in series with a mechanical oil pump. The system includes an adapter which is fitted in place of the standard oil filter, a first conduit which conducts oil from the adapter to an electrical oil pump, a second conduit which conducts oil from the electrical oil pump to a remote fitting for a standard oil filter, a third conduit which conducts oil from the remote fitting back to the adapter, and an electrical control for operating the pump, which control ensures that specified oil pressure is maintained in the system when the ignition key is turned on, and for a short period of time when the ignition key is turned off.
