Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

Reference Information

Fuel System Dampers, Billet Aluminum, Black Anodized, 40-70 psi, -8 AN Male Threads Inlet/Outlet, Standard Range, Each

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
