Individually, these pulsations are negligible, but together they create high-frequency pressure fluctuations that propagate through the fuel rail and lines.

To achieve safe and consistent rail pressure, a Fuel Pulse Damper (FPD) is often necessary. The FPD's internal diaphragm absorbs the oscillating pulses and stabilizes fuel pressure. This correction can be measured across the entire RPM range and commonly helps with idle fluctuations, especially with high-flow injectors. Furthermore, a Fuel Pulse Damper can help fix erratic lean air\/fuel mixture spikes, commonly perceived as \"misfires,\" that are difficult to tune out.\u003cbr\u003e\nMany high-performance OEM engines use an in-line fuel pulse damper from the factory, including the Toyota 2JZ-GTE, Nissan VQ35DE, and Subaru EJ20\/EJ25.
