Abstract
An apparatus which reduces engine noise caused by vibration of the fuel rail in a direct injection internal combustion engine. The apparatus includes a holder which supports a fuel inlet end of the fuel injector in the fuel cup on the fuel rail so that the fuel injector is in alignment with the direct injection fuel port in the engine head. A vibration isolator is sandwiched in between the holder and either the engine head or the fuel cup to reduce the transmission of vibration from the fuel rail to the engine head.
