Holley EFI fuel pulse dampers act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. They act to smooth out the pressure pulsations caused by the injectors opening and closing as well as the fuel pump operating. These pulsations happen so quickly that in many cases they can't be identified with an analog gauge but can cause issues with fuel delivery to the engine. Options include: * Direct-mount or inline mount * Multiple inlet/outlet dimensions * Standard or extended fuel pressure range * Male or female threads Features: * Engineered to stabilize pressure pulsations caused by the injectors opening; ideal for applications with large fuel injectors and high-volume fuel pumps * Compatible with any fuel; full anodized billet aluminum construction with stainless steel springs and fluorosilicone diaphragm * Fittings included for damper/regulators and direct-mount dampers * 1/8 in. NPT port on body of damper/regulators and inline dampers for easy installation of mechanical pressure gauge or pressure transducer * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing

Holley fuel pressure regulators with a pulse damper offer several benefits for performance and reliability. Fuel pulse dampers are designed to act in tandem with the fuel pressure regulator to further control the fuel pressure in an EFI system. These devices help stabilize fuel pressure by absorbing the pressure fluctuations (pulsations) caused by injectors opening and closing, and by the fuel pump. This leads to smoother fuel delivery, improved engine performance, and can help prevent lean spots that can cause stumbling or hesitation, especially during acceleration. Features: * Engineered to stabilize pressure pulsations caused by the injectors opening, ideal for applications with large fuel injectors and high-volume fuel pumps * Compatible with any fuel—full anodized billet aluminum construction with stainless steel springs and Fluorosilicone diaphragm * Fittings included for damper/regulator's and direct mount dampers * 1/8 in. NPT port on body for easy installation of mechanical pressure gauge or pressure transducer/ * Vacuum fitting and one foot of hose included with all dampers for vacuum referencing

Holley boost control solenoids are designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. They're driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised NOT to use the PWM+ outputs on a Holley HP ECU, but rather use the PWM- outputs. If you have a Holley Dominator ECU, use either the PWM- outputs or a PWM+ output on the J2B connector.

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
