2PCS Fuel Rail Air/Regulator Diaphragm 8M6002988 For Mercury Optimax 3.0LEngines

Mercury Part #: 8M6002988 

   This diaphragm fits both the air and fuel regulator on all of the Optimax 3.0L Model Engines (200 - 300 HP). Additionally, it is the same diaphragm used for the fuel diaphragm on the Optimax 2.5L Model Engines (135 - 175 HP).  This is the latest version from Mercury. This diaphragm is used in either regulator (fuel or air) on the port side fuel rail for the 3.0L engines, and for the fuel regulator in the port side rail for the 2.5L engines.   Most dealers tell customers they are not available separately and the entire fuel rail needs to be replaced.   That is no longer true, and they can be purchased individually without buying the entire fuel rail kit.
  The Air/Fuel diaphragm for sale is not the tracker diaphragm that is installed in the starboard fuel rail on either the 2.5L or 3.0L Optimax Engine. This diaphragm is the flat top.
