GENERAL
FUEL SYSTEM
DIESEL FUEL SPECIFICATIONS
If a large stationary fuel storage tank is used, use a pump to
remove fuel rather than a faucet. Provide a space of at least
three inches between the bottom of the pump suction pipe
and the bottom of the storage tank for settling of sediment
and water.
Locate a drain at the opposite end of the tank. Drain off the
sediment and water regularly.
Do not use the last three inches of fuel in the supply tank;
collect it in a container and allow it to settle. In this manner,
the sediment and foreign material can be separated from the
fuel and disposed of with little or no loss of fuel.

NOTE: Diesel fuel storage tanks and supply lines must
neverbegalvanized,despite the fact that the zinc coating
will reduce rust formation. Diesel fuel oil reacts chemi-
cally with zinc to form powdery flakes. Theseflakes can
chip off, causing damage to the fuel injection pump.
Refer to your Cummins Engine Operator's Manual for the
type of fuel specified.

DRAINING THE FUEL TANK

"SCHEDULED MAINTENANCE GUIDE" in Section 7 as
follows:
1. Remove a drain plug from one of the front corners of the
fuel tank.
2. When clean fuel starts running from the drain, install the
plug back in place.
