Description
The opening and closing of fuel injectors creates pressure pulses in the fuel rail;this can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.

Fuel pulse dampers can be mounted at any angle, including upside down. There are many variables that dictate if a fuel system requires fuel pulse dampers. For instance, there are cases where multiple dampers are necessary. There are also other times when the fuel system benefits with a fuel pulse damper on the return line.

Not to be used on the low pressure side of mechanical fuel pumps (including direct injection engines).

What makes Radium FPDs unique?

Along with having the flexibilty of using common fittings, Radium Engineering FPD's use a vacuum/boost reference port which allows for proper fuel pulse damper performance even at elevated fuel pressures. This becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator.

What is the difference between FPD-R and FPD-XR?

The FPD-R (green top) is slightly shorter than the FPD-XR (black top) allowing it to be used in space-contrained applications.

FPD-R base pressure requirement = 40 - 70psi (static)

Features

  • Male fitting seals using a FKM O-ring.
  • Even after tightened the newest 8AN ORB dampers (20-0776 and 20-0777), will swivel permiting the vacuum port to be clocked 360 degrees.
  • This product is safe for use with all fuel types including alcohol blends such as E85.

Included

  • Anodized and laser engraved aluminum top, R=range
  • Anodized aluminum body with male threads, 8AN ORB
  • Stainless steel hardware
  • Rubber vacuum hose, 4mm ID
  • Vacuum hose Y-fitting
