If you store quantities of fuel, good maintenance of
the stored fuel is also essential. Fuel contaminated
with water will promote the growth of “microbes.”
These microbes form “slime” that will clog the fuel
filtration system and lines. Drain condensation
from the supply tank and change the line filter on
a regular basis.
NOTE:
When a diesel engine is allowed to run out of fuel,
air is pulled into the fuel system.
If the vehicle will not start

WARNING!

Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.

Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the “Malfunc -
tion Indicator Light” to turn on.

A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
Do not open the high pressure fuel system with
the engine running. Engine operation causes
high fuel pressure. High pressure fuel spray can
cause serious injury or death.
