I just installed a new diaphragm and gasket on my 1986 Force 85 hp. When I pumped the fuel ball fuel squirted out of the fuel pump from all around. I tighten the screws but that did not help at all. I am wandering if I installed the diaphragm in wrong or was it defective. I got the kit from E-bay when I got the carburetor kit which was trash. None of the parts fit or matched. I may have the same problem with the diaphragm too. I feel the gasket was too thin. So I ended up with going to the local boat dealer getting the correct carburetor kit which fit perfectly. I am trying to get the boat ready for spring. I have read many forums that state no gasket sealant should be used in the carburetor but nothing on the fuel pump gaskets. Any help would be appreciated. I do have a service manual for my motor which does not indicate the position of the diaphragm.
