t’ll be real hard to start your vehicle
this winter if the fuel lines are plugged
with ice. But ice is what you’ll have if
you fail to keep water drained from
the fuel filtering system.
Here’s how to keep the fuel flowing
and your vehicle going:
Fill fuel tanks to within 2 inches of
the bottom of the filler neck (or to the
mark painted or stenciled on the tank).
When you fuel your vehicle, keep ice
and snow away from the tank opening.
Ground Vehicles . . .
Jet A-1 fuel does not contain an in-
hibitor, so treat it like diesel fuel.
If you’re still using old-style diesel
fuel or gasoline, consider adding icing
inhibitor to the fuel. But first, make
sure it hasn’t already been added (JP-8
comes with an inhibitor already in it).
If you can use the inhibitor, use no
more than 1 pint per 40 gallons. Too
much inhibitor will cut performance
and damage engines.
Add the inhibitor to the tank first, so
it can mix properly. How much inhibi-
tor you add depends on the amount of
fuel you mix it with.
Drain fuel filters
every
day you op-
erate. If you get more water than usual,
report it.
Here are the proper ratios:
D
rivers, moisture builds up in your
truck’s air brake system even in the
best of weather. Left alone, it corrodes
air lines, relief valves, check valves,
even the air tanks themselves.
During winter, that water turns to
ice and the problem gets even worse!
Ice plugs up the air system. If air
can’t get through, the brakes won’t
work. Water also has a nasty habit of
expanding as it freezes. It can burst
lines and fittings and ruin your brakes
completely.
Stop that problem in its tracks by
draining the air tanks after each
day’s run. And don’t forget to close
the air valves after draining. Otherwise
the valves may freeze in the open
position.
