OEM Evinrude E-TEC fuel injector kit. Includes 2 fuel rail orings, crush ring, lower and upper oring and the large outer fuel filter. This kit needs to be installed anytime a fuel injector is removed as the crush ring must be replaced. Fits all Gen1 and Gen2 injectors. Please note the fuel rail orings do not work with 15, 25 or 30hp Gen1 or on Gen2 injectors. Everything else does.
