Has anyone had any issues with the o’ring on the pto stack pipe blowing / failing.. we installed a new pump as the old one was down on performance and the oring on the stack pipe to the pto valve has blown twice.. we have used the original oem part and the pressure is within spec.. can’t see any obvious signs of damage to the pipe flange or where it sits in the valve housing.. any thoughts... it’s an SLE model
