Direct-mount fuel pulse dampers that thread directly into the fuel rail to absorb injector pressure pulses and stabilize fuel pressure throughout the RPM range. Helps with idle surge, erratic lean air/fuel ratio spikes, and stumbling issues.
Available in two pressure ranges: FPD-R (Standard Range, 40–70 psi) and FPD-XR (Extended Range, 40–105 psi). Connection options: 3/8" NPT or 8AN ORB Swivel. Features a vacuum/boost reference port and can be mounted at any angle. Safe with all fuel types including E85.
Note: Cannot be used with mechanical fuel pumps or direct injection systems.
