Fuel supply circuit

FUEL SUPPLY CIRCUIT

Operationally-speaking, the fuel supply circuit is divided into a low pressure circuit and a high pressure circuit.

The low pressure circuit consists of a tank, multifunction valve, auxiliary fuel pump submerged in the tank and a return manifold.

The high pressure circuit consists of a radialjet pressure pump, delivery manifold and injectors.
