The <strong>diaphragm<\/strong> is the flexible <strong>membrane<\/strong> that flexes back and forth inside the pump body, drawn by the <strong>lift arm<\/strong> riding on an engine <strong>cam lobe<\/strong>, drawing fuel in on one stroke and pushing it out toward the <strong>carburettor<\/strong> on the next. As rubber like this ages, the <strong>diaphragm<\/strong> can <strong>perish<\/strong>, <strong>crack<\/strong>, or <strong>lose its flexibility<\/strong>, letting fuel leak internally or reducing the pump's ability to draw fuel through, which shows up as <strong>weak fuel delivery<\/strong>, <strong>hard starting<\/strong>, or <strong>fuel leaking<\/strong> from the pump body.
