The Lincoln 20-gal Used Fluid Evacuator, No. 3650, utilizes a compressed air-operated Venturi vacuum to extract engine oil or transmission fluid directly through an automobile’s specific dipstick tube, as well as from tanks and reservoirs. The heavy duty Model 3650 features a low-profile, welded-steel tank with two durable, 4” swivel casters and two 6”, fixed-axle wheels with tough rubber treads. Its 3/4”, cam-lock connector extends from the top of the tank for convenient diaphragm pump extraction. One of five wands and three adapters can be connected to the unit’s 10’, wire-reinforced evacuation hose.
