Radium Engineering Direct-Mount Fuel Pulse Damper

The Radium Engineering Direct-Mount Fuel Pulse Damper is engineered as a purpose-built solution for enthusiasts who want the surrounding system to be easier to package, service and trust under hard use.

Why This Upgrade Matters

Injector and pump events can create pressure oscillations that are visible in the rail and can complicate tuning. A fuel pulse damper uses an internal diaphragm to absorb those oscillations and help stabilize fuel pressure in compatible electronic-fuel-injection systems.

Product-Specific Details

Radium Engineering direct-mount fuel pulse dampers absorb injector-induced pressure oscillations to help stabilize fuel pressure in compatible port-injected fuel systems.

Choose Your Configuration

• Connection: 8AN ORB / Pressure Range: 40–70 PSI — RAD20-0776: Match the connection style and pressure range to the actual rail/plumbing configuration.
• Connection: 8AN ORB / Pressure Range: 40–105 PSI — RAD20-0777: Match the connection style and pressure range to the actual rail/plumbing configuration.
• Connection: 3/8 NPT / Pressure Range: 40–70 PSI — RAD20-0178: Match the connection style and pressure range to the actual rail/plumbing configuration.
• Connection: 3/8 NPT / Pressure Range: 40–105 PSI — RAD20-0179: Match the connection style and pressure range to the actual rail/plumbing configuration.

Technical Notes

Radium' current electronic-fuel-injection dampers are intended to control pressure oscillation in compatible low-pressure EFI circuits. Radium specifically warns against using its dampers with mechanical fuel pumps or direct-injection high-pressure pump circuits.

Enthusiast Notes

If a high-flow injector setup shows pressure ripple, unstable idle or repeatable lean spikes that calibration alone cannot resolve, pressure damping is a hardware variable worth evaluating.

Before Ordering

Confirm port/thread style, base-pressure range and available clearance. Do not use Radium EFI dampers on mechanical-pump or direct-injection high-pressure circuits.
