Holley introduces its line of amazing patent pending HydraMat fuel pickups that solve 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. HydraMat is the perfect solution to this problem!

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.

  • 3/8" NPSF fitting size
  • 8 inch length
  • 8 Inch width
  • Center outlet
  • Cross shape


For best performance, the return fuel should be discharged near the pick-up of the HydraMat at a minimum distance of 1 inch above the mat.

HydraMats with a female NPT thread do not require the use of a sealing paste or tape. Use of a sealing paste or tape could result in fuel pump failure.
