Yesterday I was out fishing stopped at a spot engine running perfect. Idled about a 1/4 mile fished 1/2 hour. Took off engine running perfect got to the next spot. Shut down engine running really bad idle up and down missing. Hum seems like I have been here before. Put it on the trailer got home found fuel in the air side of the fuel rail. Yep tracker valve. Removed it found it torn right near the center metal part just like the last one. I had a spare because of all the talk of multiple failures. Installed it. Runs nice again.
185 hours on engine. Seems unusual to me. So what else should I be checking. Air pressure? Fuel pressure? Don’t use ethanol fuel. Do use premium fuel as that’s what my engine requires. Anything in the operation of the engine that can cause repeat failures?
