    951 carb question on ?missing? parts (diaphragm question)

    Thanks to kawa-doo for a bunch of PM help on this LRV rebuild so far!

    I opened the carbs for cleaning today and feel that there might be a missing diaphragm inside one of them if anyone can confirm or deny?

    The carb with the pulse line has both the rubber and clear plastic diaphragms where they should be but the carb with a fuel nipple on the side only has an o-ring and then the smooth lid to make a seal. Is that right or am I missing a diaphragm there?Click image for larger version.

ID:	311429The carb in question does not have the half inch aluminum fuel pump block in it. It literally only have the goofy shaped oring at the base along with the little strainer filter and then a cover with 4 bolts to secure it down that are way too short to even consider the possibility that the block is missing.

    Here are some more pictures showing this carburetor configuration. One of the carbs has the half inch aluminum block in between the base and the cover that you guys are referring to. That one has all of the appropriate gaskets and diaphragms. This other one in question has some other contraption attached to it at the end that I believe works as the fuel pump. If it makes any difference at all this is off of a 2001 seadoo LRVAttachment 311413

    Just decided to block of all of the outgoing ports and to put air into the fuel inlet and it held 20 psi with no air leaks using Windex to spray it down to find bubbles so this must be the correct configuration.

    Aaah, okay...so the part in the pic where I say "I think this is the fuel pump" is the accelerator pump eh?
