    2015 300Xs Fuel Pump Diagphram

    I had it replaced like 2 months ago after it blew out, and this past weekend it blew out again. Is there a better/stronger one available from Mercury or aftermarket ? Motor only has like 90hrs on it.

    Jimmy- if you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!

    Fuel pump diaphragm is only available in a KIT, Part# 857005A1. Haven't seen too many problems with the Pulse Fuel Pump Kits in the past- any chance you have a picture of the "blew out" diaphragm?
