RADIUM Engineering 20-0776 FPD-R Fuel Pulse Damper 8AN ORB Swivel

The RADIUM Engineering 20-0776 FPD-R fuel pulse damper (also called a fuel pressure damper or pulsation dampener) is made for EFI fuel systems. It screws into a female 8AN ORB port, such as one on a fuel rail. Once installed, the damper body swivels. It is compatible with all fuels.

Key Features:

• FPD-R standard operating range, intended for base fuel pressure between 40 and 70 psi
• 8AN ORB connection
• Swivel design, so the damper body can still turn after it is tightened
• Compatible with all fuels

A fuel pulse damper helps keep rail pressure steady in an EFI system. Radium recommends the FPD-R for vehicles with a base fuel pressure of 40-70 psi. Its FPD-XR version is for higher base pressures.
