Engine Fuel System

Important DO NOT reuse high pressure fuel pipes that have been removed from the engine for service procedures. If a high pressure fuel pipe was removed for an engine service procedures, replace it with a new pipe to prevent fuel leaks due to sealing surface working face deformation.

The TK488CR/CR1 engines use a common rail fuel system.

The components of the fuel system are:

  • Fuel tank

  • Electric fuel pump (with pre-filter, 40 micron)

  • Primary Fuel filter/water separator (5 micron)

  • Secondary fuel filter (3 micron)

  • High pressure fuel pump

  • Common (high pressure fuel) rail

  • Electronic injection nozzles
