2003 mercury 115 fuel pump question

[finish line 88]

The rebuild kit has 4 small disc. 2 are white plastic and 2 are black rubber. These are held in place with a small stake pin. When I disassembled my fuel pump it only had the white plastic disc. Should I be using the plastic and rubber disc or just the plastic ? I am rebuilding the fuel pump due to having some raw fuel dripping from the mid section exhaust.

As I recall the plastic is a backing plate for the rubber seal to limit it's movement. You should have instructions with your kit. I know they modified them somewhere around that model year. I no longer have my manual or I could give you a better answer.

Thanks for the reply, There was no instructions in the kit but I think it is a upgrade in the parts,
