Carb leak on 05 15hp 4 stroke

Help guys!
Have a leak on 05 15hp 4 stroke carb accelerator pump. talked to local dealer and a direct call to mercury support. In the Mercury manual they show the o-rings that go under the plate covering the accell pump diaphram. the o-rings are badly eaten from the ethanol fuel I run. Nobody can find these o-rings in their parts breakout. The diaphram and other rubber parts are not supplied in the carb kit for $79 that just isn't right.

IS THE PROPER PART NUMBER. I post this be cause I think that there are many carbs leaking out there. When you do this you should also replace the diaphram and plunger piece.
