STRUCTURE AND OPERATION

FUEL TRANSPORTATION IN FUEL TANK

FUEL TRANSPORTATION IN FUEL TANK : System Description

INFOID:0000000010838271

The electric fuel pump and the transfer jet pump are integrated with the main fuel level sensor unit, fuel filter
and fuel pump assembly. This is installed to the fuel tank. 
The transfer jet pumps draw up fuel using a flow of return fuel. The transfer jet pump (sub side) transfers fuel
from the sub side to inside of the fuel pump assembly. The transfer jet pump (main side) transfers fuel from the
main side to inside of the fuel pump assembly. The fuel sent to fuel pump assembly is supplied to the engine
by an electric fuel pump.
NOTE:
Fuel on the sub side is consumed first.
