Holley's patent-pending HydraMat solves the fuel starvation problems associated with traditional pick-ups in stock fuel tanks and racing fuel cells. Surface tension and fluid wicking let it draw fuel from nearly any area of the mat that stays in contact with fuel, storing it in an internal reservoir so the engine keeps getting fuel during hard cornering, acceleration, stopping, inclines, and low fuel conditions.
