Description of the fuel injection-ignition system
Fuel circuit
A pump located on a flange at the bottom of fuel tank pumps fuel into delivery tube (OUT) and toward
injectors. The flange also fits the pressure regulator controlling fuel feed and keeping it constant at a
value higher than engine-generated vacuum. Fuel which is not injected into intake manifolds goes back
to the flange and then to the tank by means of a return tube (IN).
