Nuke Fuel Pulse Damper 3/8 NPT (OEM style)

Beskrivning

Nuke Performance Fuel Pulse Damper, 3/8 NPT (OEM Style), engineered for stable fuel pressure in conventional EFI fuel systems.

The Nuke Performance OEM Style Fuel Pulse Damper is a compact and reliable solution for EFI fuel systems operating around a conventional base fuel pressure of approximately 3 BAR (43.5 PSI).
• OEM-style fuel pulse damper design
• Fixed operating range around 3 BAR (43.5 PSI)
• Standard 3/8 NPT connection thread
• Reduces fuel pressure pulsations
Fuel pressure pulsations are created every time the fuel injectors open and close. The internal diaphragm absorbs these pressure fluctuations, helping maintain more stable fuel pressure and smoother fuel delivery. This damper is intended for conventional EFI fuel systems operating close to 3 BAR base fuel pressure.
What is a Fuel Pulse Damper and how does it work?
A Fuel Pulse Damper is designed to absorb the high-frequency pressure fluctuations created every time the fuel injectors open and close. Using an internal diaphragm, it helps stabilize fuel pressure, contributing to smoother fuel delivery and improved fuel system consistency.
The OEM Style Fuel Pulse Damper is based on the classic fixed-range damper design commonly used in production EFI fuel systems. Designed for applications operating around 3 BAR (43.5 PSI) base fuel pressure, it provides a compact and straightforward pulse damping solution without the need for vacuum/boost reference or additional adjustment.
Where should a Fuel Pulse Damper be installed, and when should I choose the OEM Style version?
For best performance, install the Fuel Pulse Damper as close to the fuel injectors as possible, typically on or near the fuel rail using the 3/8″ NPT connection.
The OEM Style Fuel Pulse Damper is ideal for EFI fuel systems operating around 3 BAR (43.5 PSI) base fuel pressure, where a compact, fixed-range damper is preferred. For higher base fuel pressures or applications requiring vacuum/boost reference capability, choose the Nuke Performance FPD70 or FPD110 series instead (available here).
