Fuel Boost Pump / Fuel Transfer Pump: Description and Operation
PURPOSE
JET PUMP (AWD Model Only)
-
The jet pump utilizes the velocity of fuel returning from the engine to produce negative pressure inside the jet pump, this negative pressure allows
fuel to be sucked up.
-
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.
