FUELING
Do not fill the tank from both necks at once or
have both fill caps open; the tank will over-fill
and overflow.
Two diesel ( ULSD ) fuel fillers are installed on
the coach. One is located behind a filler door in the
fuel tank compartment door on the curbside and the
second location is on the roadside behind a filler door
in the A/C condenser door ( Figures 95 and 96 ).

DO NOT put anything but DEF in the DEF tank

One diesel exhaust fuel (DEF) filler door is next to
the curbside diesel (ULSD) filler door ( Figure 97 ).
