To tell the truth all i know is it is a recommended add on but not totally sure how it works, i'll try to describe what mine looks like.
bracket to secure to car
two pipes on top, obviously for in and out
to outlets on the side which join each other with transparent tube??
screw on the top??
and screw on the bottom, to drain excess oil?it seems to be magnetized
plus an added threaded pipe connector that the thread only fits the top screw
also added pic
