***LIMITED RETURN POLICY*** Used with the Mityvac fluid evacuator on motors with a threaded garden hose style dipstick tube. Not all Yamaha motors have a threaded dipstick tube and will need a different non-threaded adapter. The threaded fitting on the end of the adapter threads onto the MOTOR. The tube that comes with the Mity Vac is then inserted into this adapter hose. This creates the vacuum necessary for extracting the oil from your motor.
