I bought a fuel pump kit for my '89 mariner 75 oil injected. The new diaphram ( Sierra 18-7818-1 ) had 2 holes that the old one did not have, I thought it was maybe an improved design, but when I put it on it flooded the no 3 cylinder. My serial no is OB345429. The part they sent is what the book calls for. Anybody have any idea what kit I need.

Thanx
