Dodge 2007 Ram Chassis Cab - Manual (Page 336)

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
WARNING!
• Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
(See Section 7 for Maintenance Procedures).
NOTE: Climatized Ultra Low Sulfur diesel fuel is a
blend of Number 2 Ultra Low Sulfur and Number 1 Ultra
Low Sulfur Diesel fuel which reduces the temperature at
which wax crystals form in the fuel.
Bulk Fuel Storage
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 fuel filters 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.
