RADIUM Engineering 20-0178 FPD-R Fuel Pulse Damper Direct Mount 3/8 NPT

The RADIUM Engineering FPD-R (Fuel Pulse Damper-Range) is designed to solve fuel pressure instability caused by the opening and closing of fuel injectors. The FPD's internal diaphragm absorbs oscillating pulses and stabilizes fuel pressure throughout the RPM range, helping reduce idle surge especially with high-flow injectors.

Key Features:

• Internal diaphragm absorbs oscillating pulses and stabilizes fuel pressure, measurable throughout the RPM range
• Helps solve erratic lean air/fuel ratio spikes and stumbling that are difficult to tune out
• Vacuum/boost reference port allows proper performance even at elevated fuel pressures, essential for boosted systems with 1:1 rising rate fuel pressure regulators
• Compact design with green anodized top, slightly shorter than FPD-XR for space-constrained applications
• Base pressure requirement: 40-70 psi static
• Compact 1.64 inch height

Construction:

• Anodized and laser engraved aluminum top with green finish
• Anodized aluminum body with male 3/8 inch NPT threads
• Stainless steel hardware included
• NPT tapered threads allow vacuum port to be clocked to desired location during tightening

Installation & Compatibility:

• Can be mounted at any angle including upside down; best results when mounted directly onto fuel rail
• Safe for use with all fuel types including alcohol blends such as E85
• Includes rubber vacuum hose (4mm ID) and vacuum hose Y-fitting
• Not recommended for low-pressure side of mechanical fuel pumps

This direct mount fuel pulse damper kit provides professional-grade fuel pressure stabilization for performance and racing applications, helping eliminate fuel delivery issues that can compromise engine performance and tuning.
