    Accelerator Pump Leaking



    1991 Merc 115
    pulling my uncles motor out of the graveyard, hasn’t run in years. Got her fired up this aft, but the accelerator pump is leaking like a water fountain out of this vent hole. Exactly like this guys in the YouTube video.
    Problem is, I can’t find a gasket kit for it. Only the whole pump for like $200!!!!
    square fuel pump kits are easy enough to find.... but I’m blanking here.

    Can anyone else source this?

    This is my first stop when trying to find part numbers. You will need the serial number off the motor for Mercury though.

    Love that site. I also use CrowleyMarine.com

    But on marineengine.com, I went to:http://www.marineengine.com/parts/me...e-reference-16

    Part # 38 on that diagram is what's leaking. They don't break it down like they do the fuel pump.
    Called my local Silver Spring marine in southern RI, they found the kit in their computer for $34. Wonder why I can't find it online.
