Figure 50.
FUELING
Two (2) 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 (Figure 51.).
The second location is on the roadside behind a filler
door in the A/C condenser door.
Figure 51. Diesel (ULSD) Fuel Door
The fuel tank is equipped with a whistle that stops
when the tank is full. Close filler and latch it securely
after filling.
Do not fill the tank from both necks at once or
have both fill caps open; the tank will over-fill
and overflow.

One (1) diesel exhaust fuel (DEF) filler door is

(Figure 52.).

Diesel Fuel Specification
Engines must comply with EPA mandated low
emission guidelines by using ULSD (ultra low
sulfur diesel) fuel.
Failure to use ULSD fuel in 2015 EPA engines
will result in component damage.
Diesel Exhaust Fuel (DEF) Specification
DEF must meet ISO standard 22241-1.
Diesel Fuel System Maintenance
The fuel filter(s) require(s) periodic maintenance,
and fuel lines and connections must be inspected
regularly for evidence of leaks. When filling the
tank, take care to prevent the entry of dirt and
water. See the MCI Maintenance Manual and the
