Pressure Relief Valve Question

[det398]

I have a 1989 mercury V135, OC219126 is the serial number if that will help anyone. I am looking for a pressure relief valve kit as I suspect that is the problem from some of the other postings I have read. Does anyone know where I can find that on a drawing and a part number for it? Thanks for any help in advance.<br />Any additional advice in the installation of it would be equally appreciated. Thanks

Not really,<br /><br />The carrier and grommet are not going to come out with the poppet. The carrier is fixed to the hole in the block and the grommet fits into the carrier. So if you replace those you will have to use some needle nose pliers or some small fingers to get them out. <br /><br />When you put everything back together just make sure that the diaphram fits in place within the groves on both the inner and outer cover plates to get a good seal.
