5.4 POLYETHYLENE FUEL TANK REPAIR

NOTE
Fuel level must be lower than perforation to
carry out this procedure.
WARNING
Park vehicle safely, apply parking brake, stop
engine and set battery master switches to the
OFF position before working on the vehicle.
1. Locate perforation on fuel tank.
2. If necessary, remove fuel tank as per
instructions in this section.
3. Drill perforation with a 23/64" bit. Make sure
drill hole is perfectly round.
4. Insert a screw (Prevost #500196) and a
washer (Prevost #5001244) into anchor nut
(Prevost #500331).
5. Place assembly in drilled hole. Tighten screw
by 10 complete turns. Refer to Figure 14.
6. Apply sealant on

6. FUEL SPECIFICATIONS

The quality of fuel used for high-speed diesel
engine operation is a very important factor in
obtaining satisfactory engine performance, long
engine life and acceptable exhaust emission
levels.
The U.S. Environmental Protection Agency
(EPA) has issued new standards to improve air
quality by significantly reducing emissions
through a combination of cleaner-burning diesel
engines and vehicles.
To meet EPA standards, the petroleum industry
produces Ultra Low Sulfur Diesel (ULSD) fuel,
head plug (Prevost

SECTION 03 : FUEL SYSTEM
also referred to as S15, containing a maximum
of 15ppm (parts-per-million) sulfur.
On-highway diesel engines
emission regulations are designed to operate
ONLY with ULSD fuel. ULSD fuel will enable the
use of cleaner technology diesel engines and
vehicles with advanced
devices, resulting in significantly improved air
quality.

6.1 FUEL TYPE

EPA-10 and later engines like the Volvo D13 are
designed to run on Ultra Low Sulfur Diesel
(ULSD) fuel, which can contain no more than 15
ppm sulfur.
Fuel used must meet engine manufacturer's
specification. Refer
specifications.
CAUTION
ULSD fuel is necessary to avoid fouling the
engine's Exhaust Aftertreatment
Improper fuel use will reduce the efficiency of
the engine's Aftertreatment System and may
permanently damage the system.
CAUTION
Owners of 2010 and later model year on-
highway diesel engine must refuel only with
ULSD fuel.
NOTE
Burning Low Sulfur Diesel fuel (instead of
ULSD fuel) in 2010 and later model year
diesel engines is illegal and punishable with
civil penalties.
