7.8 FUEL SYSTEM
The fuel system includes a fuel tank (Fig. 7-17, 1), fuel
level sender with gasket (2), instrument cluster gauge
(not shown), fuel strainer (3), fuel lift pump (4), fuel filter
(5), fuel supply hose (6) and fuel return line (7).
The threaded fuel filler (Fig. 7-17, 8) has a keyed fuel cap
(9) and permits entry of diesel fuel into the tank.
The fuel level sender (Fig. 7-17, 2) and instrument
cluster gauge are described in Section 9.15.14, “Fuel
Level Indicator and Fuel Level Sender.”
A fuel supply hose (Fig. 7-17, 6) carries fuel from the tank
(1) to the fuel lift pump (4) and then under pressure to the
fuel filter (5). Filtered fuel is directed to the fuel injection
pump and to the individual fuel injectors. Surplus fuel at
the fuel injector pump is returned to the tank via the fuel
return line (7).
