Radium Engineering In-Line Fuel Pulse Damper Kit - Universal

Radium Engineering In-Line Fuel Pulse Dampers allows for proper fuel pulse damper performance even at elevated fuel pressures, and are very easy to install.

The kit features an anodized aluminium housing with a large 0.69" center bore that uses two in-line inlet/outlet ports that are machined with 3/4"-16 UNF threads for 8AN ORB fittings. Depending on the size of the fuel feed hose used, there are 3 kits to choose from which include different male adapter fittings (-6AN, -8AN, -10AN). These fittings seal to the billet housing using Viton O-rings.

The difference between FPD-R and FPD-XR, is that the FPD-R is slightly shorter than the FPD-XR allowing it to be used in space-contained applications (see images).

The FPDs can be mounted at any possible angle including upside down. For best results, the damper should be mounted directly onto the fuel rail(s).

This product is safe for use with all fuel types including alcohol blends such as E85.

Product Description

Radium Engineering In-Line Fuel Pulse Dampers allows for proper fuel pulse damper performance even at elevated fuel pressures, and are very easy to install.

The opening and closing of fuel injectors creates pressure pulses in the fuel rail which 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.

Along with having the flexibility 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.

The kit features an anodized aluminium housing with a large 0.69" center bore that uses two in-line inlet/outlet ports that are machined with 3/4"-16 UNF threads for 8AN ORB fittings. Depending on the size of the fuel feed hose used, there are 3 kits to choose from which include different male adapter fittings (-6AN, -8AN, -10AN). These fittings seal to the billet housing using Viton O-rings.

The difference between FPD-R and FPD-XR, is that the FPD-R is slightly shorter than the FPD-XR allowing it to be used in space-contained applications (see images).

The FPD-R (Fuel Pulse Damper-Range) and FPD-XR (Fuel Pulse Damper-Extra Range) both have unique base "static" fuel pressure requirements:

  • FPD-R base pressure requirement = 40 to 70PSI (static)
  • FPD-XR base pressure requirement = 40 to 120PSI (static)
  • Base pressure is the fuel pressure measured when the fuel pump is running WITHOUT a vacuum line connected to the regulator

Using the supplied M6 bolts/nuts, the FPD In-line kit can be mounted at any possible angle including upside down. For best results, the damper should be plumbed as close to the fuel rail(s) as possible. Like any fuel system part, the FPD kit should be kept away from areas with excessive heat.

This product is safe for use with all fuel types including alcohol blends such as E85.
