Same experience here. My fuel pump diaphragm split one day . Sent a picture to Franz at Franz Marine and his reply was - been using Ethanol in that motor, right ? That's how I found out about the issue. The old rubber does not react well to the stuff, hardenes and splits, plus it causes water/moisture issues, and the motor just doesn't well as well..
Good post on that issue !
