Fuel Supply Line: Description and Operation
PURPOSE/OPERATION
The Fuel Line system utilizes two sets of fuel lines located underneath the vehicle on the right side.
Fuel Feed (Supply) Line
The Fuel Feed (Supply) Line delivers fuel pressurized by the in-tank electric Fuel Pump from the Fuel Tank. The fuel is fed into the Fuel Filter,
from there to the Fuel Rail.
Fuel Return Hose
This line is connected between the Fuel Pressure Regulator and the Fuel Tank. When the Fuel Rail Pressure exceeds the specified amount, the Fuel
Pressure Regulator opens and bleeds the excess fuel through this line and back into the Fuel Tank.
