Fuel Filter - Renault 2000 Megane Technical Note

The fuel filter is located in the engine compartment. It is contained in an unremovable cartridge. This cartridge
contains a regulating valve which limits the flow of diesel circulating to the engine.
To replace the filter it is therefore necessary to replace the whole unit.

REFITTING
It is vital that you respect the position of the
connections to the filter.
Be careful not to squeeze or damage the pipes.

It should be in open position for normal operation.
To reprime the circuit after an intervention, a filter
change or a fuel fault you should:
– close the fuel cock (R),
– start the low pressure pump by switching on the
ignition several times,
– start the engine,
– OPEN THE FUEL COCK (the valve is open when the
