Do I need a fuel damper in my fuel system?

This is a question that we often hear from our customers.  The easiest way to find out is to monitor your vehicle’s fuel pressure at peak power, wide open throttle.  A session on the chassis dyno is recommended for this test. Do NOT use a liquid-filled or dampened fuel pressure gauge for this test!    At peak power, the fuel pressure gauge should not flutter more than 4-5 PSI.  Also, a damper is recommended if one of more of the following conditions exist:

• Batch-fire injection is used
• Engine RPM will exceed 8000 RPM
• 5 or more injectors are used per fuel rail
• To replace a factory-installed fuel damper

For high-power applications, it is recommended that a damper be installed on EACH fuel rail for maximum effectiveness.
