Dodge 2006 Ram Pickup 3500 - Manual (Page 315)

Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and follow
the cold weather advice above, fuel conditioners should
not be required in your vehicle. If available in your area,
a high cetane “premium” diesel fuel may offer improved
cold-starting and warm-up performance.
ADDING FUEL
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
• Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is properly
tightened.
• Make sure that the gas cap is tightened each time the
vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a container
that is inside of a vehicle or in the bed or on the
opened tailgate. Always place fuel containers on the
ground while filling.
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door. If the gas cap is
lost or damaged, be sure the replacement cap is for use
with this vehicle.
