POWER SYSTEM OPERATION (Contd)
b.
Fuel System (Dual Tank) Operation.
(1)
The fuel system stores, cleans, and supplies fuel to the fuel injectors where it is mixed with air to initiate
engine combustion.
(2)
The fuel system is not identical for all models. Vehicles covered in this manual have either one or two
tanks. These tanks can also differ in capacity. See table 1-6, Capacities for Normal Operating
Conditions, for these differences.
(3)
A typical two-tank fuel system is described below. A single tank is described later in paragraph 1-18c.
Both systems include fuel supply, return, and vent lines to provide fuel flow and release the fumes
throughout the system. Major components of fuel system (dual tank) are:
A
RIGHT TANK (FRONT) VENT LINE - Vents vapors from fuel tank to vent hole in air intake stack.
B
RIGHT TANK FILLER CAP - Covers fuel filler opening on right fuel tank.
