Fuel Injection (Fuel System)
2. JET PUMP
! The jet pump utilizes the velocity of fuel returning from the engine to produce negative pressure
in it.
! Using the pumping effect produced by the negative pressure, the jet pump transfers fuel from
the sub-compartment to the main compartment of the fuel tank.
! When the return line nozzle is clogged, the fuel sent back through the return line flows back into
the fuel tank via the relief valve.
