Fuel System - Mazda 626 MX-6 Workshop Manual

FUEL SYSTEM

This system supplies the fuel necessary for combustion at a constant pressure to the injectors. Fuel
is metered and injected into the intake manifold according to the injection control signals from the en­
gine control unit. It consists of the fuel pump, fuel filters, delivery pipe, pulsation damper, pressure
regulator, injectors, fuel pump switch (incorporated in the air flow meter), and the circuit opening relay.
The fuel pump is mounted in the fuel tank to minimize the operating noise of the fuel pump. The injec­
tors are directly supplied with battery voltage through the main relay. The connector of the injectors
is black to distinguish the injectors for the turbocharged engine from those of the non-turbocharged
engine.
