ENGINE FUEL SYSTEM
The fuel system used on the Thermo King TK 3.74 diesel is
a high pressure system used in conjunction with a precham-
ber.
The components of the fuel system are:
1.
Fuel tank (may be the truck fuel tank).
2.
Electric Fuel pump.
3.
Fuel filter.
4.
Injection pump.
5.
Injection nozzles.
A 10 psig (69 kPa) electric fuel pump pulls fuel from the
fuel tank through a prefilter, then pushes it to the fuel filter,
and to the injection pump. The prefilter is designed for
diesel fuel and is the only type that should be used.
