I have an 05 Bandit 254 with a Cat/Perkins 1104C motor As of recently when the chipper is shut down, especially at the end of the day, it will not start back up after it sits. It has got progressively worse. It started after sitting for a period of time (over night) not its everytime its shut down for even the shortest period of time. We have to prime whole system then it will fire up. Once it's running, it runs fine. Injection pump was just done, Hood safety switch was just replaced, new filters. Also, the return line to the tank seems like its spitting fuel back into the tank much weaker, I am thinking pump that the filter screws into? Any thoughts would be appreciated. Thank you!
