TM 1940-20/2
a.
Fuel Tank - is located on the centerline of the boat between the battery compartments and slightly forward of
the engines. The tank is provided with a vent that vents fumes to the atmosphere and a filler cap for filling the
tank. The filler cap has a dipstick for determining the exact amount of fuel in the tank. The tank is designed to
prevent an explosion if the tank is penetrated by a bullet.
b.
Isolating Valve - is located at the bottom of the tank and is used to isolate the fuel tank from both engines.
c.
Shutoff Valve - is located near the top of the fuel tank and is used to isolate the engine from the fuel tank.
d.
Fuel Water Separator - is located near the top of the fuel tank and is used to remove water and coarse particles
from the fuel.
e.
Fuel Tank Vent - is located next to the filler cap on the tank and extends over to the port side of the boat.
f.
Feed and Return Lines - are the nylon tubing that connect the engines to the fuel tank. The feed line supplies
fuel to the engine. The return lines return excess fuel back to the tank.
Fuel Lift Pump - is located on the right side of the engine near the rear mounting brackets. The fuel lift pump
g.
supplies fuel to the injection pump during start-up and operation.
h.
Fuel Filters - are the double bowl arrangement above the fuel lift pump. These filters remove particles from the
fuel that could clog the injection pump or the injectors.
i.
Injectors - inject fuel into the engine cylinders.
Filter/Reservoir - is located on the left side of the engine near the intercooler and has a small screened knob
j.
on top.
k.
Thermostarter - is located on the left side near the bottom of the air intake manifold. The thermostarter is used
to heat the incoming air when the engine is started at temperatures below 50F (10C). The thermostarter
operates by electrically igniting a small amount of fuel in the air intake manifold.
l.
Collector - is located near the fuel lift pump and is a collecting point for excess fuel from the filter/reservoir and
leak-off from the injectors.
m.
Injector Pump - is located on the right side of the engine. It delivers an accurately measured quantity of diesel
oil, under pressure, to the injector through which the fuel is injected into the engine cylinder.
