Fuel system — general information On Megane III and Fluens vehicles, a fuel supply system is installed without a fuel return line to the tank. The fuel supply pressure is independent of the engine load. The system consists of the following components:...
Removal and installation of the fuel rail and nozzles The injectors are attached to the fuel rail with holders. Fuel constantly circulates around the circumference of the injector body, which avoids the formation of gasoline vapor bubbles and facilitates starting a hot...
Checking the electric fuel pump (all engines) Disconnect the fuel feed line from the fuel rail. Connect the piping with the pressure gauge from the test kit (Mot. 1311-01) to the tee of the device (Mot. 1311-08) and the fuel supply line - to the tee of the rail...
Fuel pressure check (all engines) Note. Fuel pressure gauges and adapters are used to measure fuel pressure (Mot. 1311-01) and tee-adapter (Mot. 1311-08). Remove the engine top cover. Disconnect the fuel supply pipe fitting from the fuel rail....
Knot «fuel pump — fuel gauge — fuel filter» (all engines) Place the car on a lift. Disconnect the battery. Drain the fuel from the fuel tank. Remove: upholstery of the luggage compartment; baggage hold device. Remove: subframe mounting bolts (1); subframe trim (2); plastic...
Fuel tank (all engines) Overpressure-vacuum safety valve In case of shutdown of the gasoline vapor recirculation circuit, this valve avoids the creation of excess pressure in the tank (tank swelling) or rarefaction (due to fuel consumption,...
