The Toledo design relies on compressed air to make fluid extraction easy and super quick. With a 1.6 litre per minute extraction rate and an opaque 1 litre fluid reservoir, the job will be done before you know it. In the kit is a flexible but firm suction hose, a rubber hose adaptor, bleed nipple adaptor and two hanging hooks. Connection to an air compressor is achieved by means of a 1/4" thread in the bottom of the gun. Just install your choice of air fitting, set the compressor anywhere between 90 and 170PSI and youre ready to go.
