Holley HydraMat Fuel Pickups
The amazing HydraMat fuel pickups feature Holley's patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks, as well as racing fuel cells. During hard cornering, acceleration, stopping, inclines, and low fuel conditions fuel runs away from the fuel pick up which introduces air into the system resulting in poor engine performance and even stalling. The Holley HydraMat fuel pickups are the solution! Surface tension and fluid wicking are the secrets of the HydraMat, giving it the amazing ability to draw from nearly any area that has contact with fuel and then store it in its internal reservoir. As an area of the HydraMat is uncovered, the tiny pores of the media seal off through surface tension, forcing fuel to be contained in the reservoir and drawn from other areas of the mat where fuel continues to be available. The sheer size and coverage area of the HydraMat allows it to pull fuel from virtually any area in the tank or cell eliminating the need for specialty reservoirs and pick up pumps saving cost and greatly reducing complexity. Holley HydraMats are available in various sizes and shapes to fit a wide variety of stock fuel tanks and/or race fuel cells. Features and benefits: * Patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks as well as racing fuel cells * Greatly reduces the potential for air to enter into the fuel system which can result in poor engine performance and/or engine stalling * Perfect for vehicles experiencing fuel starvation during hard cornering, acceleration, stopping, inclines, and low fuel conditions * Surface tension and fluid wicking allow the HydraMat to continue to draw fuel from the tank or cell even when part of the mat uncovered * As an area of the HydraMat is uncovered, tiny pores in the media seal off through surface tension, forcing fuel to be drawn from other areas of the mat where fuel continues to be available * Unique internal reservoir assists in keeping fuel available at the pickup even under extreme fuel slosh conditions * Eliminates the need for specialty reservoirs, sumps and pick up pumps saving cost and greatly reducing complexity * Also acts as a 15 micron pre-filter eliminating the need for a separate filter before the fuel pump * Can be folded and compressed for easy installation through a variety of fuel cell openings * HydraMats are also available in other sizes and shapes to fit a variety of stock fuel tanks and/or race fuel cells * Not for use with diesel fuels
