A pair of custom stainless-steel tanks houses the hydraulic oil. Each tank is designed to trap oil in the suction area and keep air bubbles at the top of the tank. The shape of each tank and the pickup position keep the air pocket away from the suction port when sloshing around. Further, the tank shape makes the oil take the longest route possible back to the suction port so the oil has a chance to dwell and let the bubbles work their way out before being sent back to the pump.
