PROBLEM

Show/hide table

The HEUI pump needs to be replaced on certain C9 Marine Genset Engines. The existing HEUI pump can generate a high pressure oil leak between the fuel transfer pump housing and main pump housing. Due to the nature of this failure in this application, a fire could be generated and may result in personal injury or death. The new pump will also incorporate improved components internally, which should increase the durability of the pump.
