WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Fuel tank is equipped with a primary and a secondary fuel pump. Pumps are mounted on top of each side of fuel tank. The secondary fuel pump transfers fuel from one side to the other side of the fuel tank where the primary pump is located. Primary pump supplies fuel to the fuel injectors.
