    i have a Pete 348 with the 8.3 Cummins isc. I am getting open code for line heater circuit number 4. I can find 1-3 line heaters on the lines coming from the pump. I am having trouble locating number 4. Any help would be appreciated

    #4 line heater is the internal pump heater. Pull off the 12 pin connector to the def pump, I imagine it is full of def as the pump cracked internally.
