After following each step in the order
listed and
finding
the problem,
let’s say,
"The

How do you fix the problem?
Turn to paragraph 3-33.
This is the maintenance procedure for the fuel solenoid valve.

are always made aware of the warnings
and cautions you need to know for personnel and equipment safety.
The M915A1 Truck Tractor and equipment are non-metric and do not require any metric
tools.
Therefore,
metric
units are
not supplied
in
this
manual.
Furthermore, for the sake of clarity, tactical instructions will also remain non-
metric.
