I remember a post from last year that I cannot find. It was regarding a part in the fuel system that is extremely vulnerable to failure due to hitting the rev limiter. I believe it was some type of rubber bladder that would blow out causing a lean condition and eventually engine failure. I did hit the rev limiter more than I wished to last year and just to be safe, I wanted to replace this part when I pull her out in the spring. Does anyone know what it was and/or how much it costs ?
