Inline fuel pulse damper kits to stabilize fuel pressure fluctuations caused by injector opening and closing cycles. The internal diaphragm absorbs oscillating pulses, improving idle surge and erratic lean air/fuel ratio spikes.
Available in two pressure ranges: FPD-R (Standard Range, 40–70 psi base pressure) and FPD-XR (Extended Range, 40–105 psi base pressure). Connection options: Barb, 6AN, or 8AN. Includes vacuum/boost reference port, anodized aluminum components, stainless steel hardware, and rubber vacuum hose. E85 compatible. Can be mounted at any angle.
Note: Cannot be used with mechanical fuel pumps or direct injection systems.
