NOTE
For Export
vehicles, the fuel gauges
will not state: ULTRA LOW SULFUR

ent draw tube locations. Because of
this and the amount of road crown,
it is recommended that you do not
operate your vehicle with less than
one-quarter of your truck’s fuel capac

one-quarter of capacity could result
in the lack of fuel to keep the engine
running. In addition, you will want to
keep the fuel tanks at least half-full to
reduce condensation of moisture in
the tanks. This moisture can damage
the engine.
