pressure microdampers. The microdampers suppress
fuel pressure pulses that occur when each fuel injector is
activated.
The microdampers are considered “life of engine”

microdamper is removed, apply a light film of two-stroke
engine oil to the o-ring during installation.
Torque clamp fasteners to specification.
NOTE: A threaded plug is located on the MAG end of
ra
il. Do not remove plug.
