PROBLEM
The existing Electric Lift Pump (ELP or Fuel Transfer Pump) can fail due to either over voltage spikes or from compromised fuel supply on certain C4.4, C6.6, and C7.1 Industrial Engines.
If the existing Electric Lift Pump (ELP or Fuel Transfer Pump) fails it may result in the engine not stalling due to using fuel from the fuel return line into the secondary filter. The failure of the ELP may also result in blown fuses / tripped circuit breakers and high fuel temperatures. Some C7.1 Litre engines may see a failure to regenerate the DPF.
In some instances the engine may stall or derate.
The replacement ELP will prevent the damage caused by over voltage spikes. The replacement of the air vent connector will prevent fuel from being pulled along the fuel return line into the secondary filter.
