ABSTRACT:
Adapter for connecting a by-pass oil filter to an internal combustion engine equipped with a full-flow, throw-away, replaceable oil filter. Adapter would form an adjustable clamp band around the annular surface of the full-flow filter and would embody an appropriate penetrating device consisting of a sharpened hollow needle or penetrating pin which would automatically penetrate the annular surface of the full-flow filter when the adapter band is securely tightened, opening up access to a small supply of engine oil to be transferred to the by-pass filter via appropriate connections.
