I've got a 91 evinrude E150EXEIS that needs the rebuild kit for the vapor pump assy. I ordered the recommended VRO rebuild kits from my local dealership, but none included the vapor pump rebuild kit i need. I ordered the following kits. Housing (174127), kit assy (436095) and kit assy (435921). The vapor pump assy i have is (433352). My parts catalog lists only one of two diaphrams i need (331307). Does anyone have the part # for the "other" gasket? Thanks for your help.
