A vibration isolation assembly is provided for use with a backfill tamper. In use, the vibration isolation assembly can be disposed between a handle and a percussion mechanism of the tamper and absorbs kickback forces from the percussion mechanism during backfill tamper operation. In one embodiment, the assembly includes an elongated conduit member that defines a passageway that allows compressed air to pass through the member to the percussion mechanism and a vibration dampening piston arrangement for absorbing feedback forces from the percussion mechanism during backfill tamper operation. The assembly may further include a spring arrangement for dampening vibration emanating from the piston.
