FUEL TANK
DESCRIPTION
The fuel tank is constructed of a plastic material.
Its main functions are for fuel storage and for place-
ment of the fuel pump module. The tank is made
from High density Polyethylene (HDPE) material.If
equipped with ORVR (Onboard Refueling Vapor
Recovery) it has been added to the fuel tank to con-
trol refueling vapor emissions.
OPERATION
All models pass a full 360 degree rollover test
without fuel leakage. To accomplish this, fuel and
vapor flow controls are required for all fuel tank con-
nections.
All models are equipped with either one or two
check valves mounted into the top of the fuel tank (or
pump module).
An evaporation control system is connected to the
check valve(s)/control valve(Refer to 25 - EMIS-
SIONS CONTROL/EVAPORATIVE EMISSIONS/
ORVR - OPERATION) to reduce emissions of fuel
vapors into the atmosphere, when the tank is vented
due to vapor expansion in the tank. When fuel evap-
orates from the fuel tank, vapors pass through vent
hoses or tubes to a charcoal canister where they are
temporarily held. When the engine is running, the
vapors are drawn into the intake manifold. In addi-
tion, fuel vapors produced during vehicle refueling
are allowed to pass through the vent hoses/tubes to
the charcoal canister(s) for temporary storage (priorto being drawn into the intake manifold). All models
are equipped with a self-diagnosing system using a
Leak Detection Pump (LDP) or Natural Vacuum
Leak Detection (NVLD). Refer to the Emission Con-
trol System for additional information.
INLET CHECK VALVE
All vehicles have an inlet check valve on the inside
of the fuel tank at the filler inlet
The valve prevents fuel from splashing back on
customer during vehicle refueling. The valve is a
non-serviceable item.

FUEL DOSING PUMP
DESCRIPTION
The dosing pump is a combined delivery, dosing
and shut-off system for the fuel supply to the supple-
mental cabin heater from the vehicle fuel tank.
OPERATION
The dosing pump is an electrically operated pump
that receives its operation instructions from the sup-
plemental cabin heater control module. The pump
supplies diesel fuel from the vehicle fuel tank to the
cabin heater.
REMOVAL
NOTE: The dosing pump is serviceable without
removing the supplemental cabin heater from the
vehicle.
(1) Disconnect and isolate the negative battery
cable.
CAUTION: Make sure that the hoist is properly posi-
tioned under the vehicle to prevent damage to the
flexible section of the cabin heater exhaust tube.
(2) Raise and support the vehicle.
(3) Disconnect the wiring harness connector to the
dosing pump by depressing the integral spring and
pulling the connector away from the pump.
NOTE: Utilize an approved fuel storage container to
catch any residual fuel that may drain from the
heater fuel hose or the dosing pump.
(4) Remove the clamp that secures the heater fuel
hose to the dosing pump (Fig. 4).
(5) Disconnect the heater fuel hose from the dosing
pump.
NOTE: Position and retain the heater fuel line to
prevent fuel leakage from the cabin heater unit
while servicing the dosing pump.
(6) Disconnect the fuel line between the dosing
pump and the cabin heater unit.
NOTE: Have an approved fuel storage container
ready to catch any residual fuel that may drain from
the fuel line or the cabin heater unit.(7) Remove the dosing pump from the rubber iso-
lator and the vehicle.
INSTALLATION
(1) Position the dosing pump to the vehicle and
onto the rubber isolator.
(2) Connect the fuel line between the dosing pump
and the cabin heater unit.
NOTE: The connectors should point towards the
cabin heater fuel line.
(3) Connect the heater fuel hose to the dosing
pump.
(4) Install the clamp that secures the heater fuel
hose to the dosing pump. Tighten the clamp securely.
(5) Connect the wire harness connector to the dos-
ing pump by depressing the integral spring and
pushing the connector toward the pump. Verify con-
nector installation.
(6) Lower the vehicle
(7) Reconnect the negative battery cable.
(8) Verify function of the supplemental cabin
heater.

STANDARD PROCEDURE
CLEANING
(1) Remove the cabin heater fuel line (Refer to 24 -
HEATING & AIR CONDITIONING/CABIN HEAT-
ER/FUEL LINE - REMOVAL).
(2) With the cabin heater fuel line removed from
the vehicle, place a shop cloth on the fuel tank end of
the fuel line to catch any residue, then apply a small
amount of air pressure to the other end of the fuel
line.
(3) Check to see if air pressure is coming from the
tank end of the line. If pressure is flowing unre-
stricted the line is clean.
(4) If the fuel line shows any signs of being
restricted after air pressure is applied, the fuel line
should be replaced.
(5) Install the cabin heater fuel line (Refer to 24 -
HEATING & AIR CONDITIONING/CABIN HEAT-
ER/FUEL LINE - INSTALLATION).
(6) Verify function of the cabin heater.
REMOVAL
CAUTION: Make sure that the hoist is properly posi-
tioned under the vehicle to prevent damage to the
flexible section of the cabin heater exhaust tube.
(1) Raise and support the vehicle.
NOTE: Utilize an approved fuel storage container to
catch any residual fuel that may drain from the
heater fuel hose or the dosing pump.
(2) Remove the two clamps that secure the heater
fuel hose to the dosing pump and the heater fuel line
(Fig. 5).
(3) Disconnect the heater fuel hose from the dosing
pump and the heater fuel line.
(4) Remove the clamp that secures the heater fuel
line to the fuel tank.
(5) Disconnect the heater fuel line from the fuel
tank.
(6) Disconnect the fuel line from the body retain-
ing clips and remove the fuel line from vehicle.
INSTALLATION
WARNING: DO NOT OPERATE THE DIESEL SUP-
PLEMENTAL CABIN HEATER IN AN ENCLOSED
AREA SUCH AS A GARAGE THAT DOES NOT HAVE
EXHAUST VENTILATION FACILITIES. ALWAYS VENT
THE CABIN HEATER EXHAUST WHEN OPERATING
THE CABIN HEATER. ALLOW THE DIESEL SUPPLE-
MENTAL CABIN HEATER TO COOL BEFORE PER-
FORMING ANY SERVICE PROCEDURES TO THE
CABIN HEATER. VERIFY THAT ALL DIESEL SUP-
PLEMENTAL CABIN HEATER FUEL LINES ARE
SECURELY FASTENED TO THEIR RESPECTIVE
COMPONENTS BEFORE PERFORMING ANY SER-
VICE PROCEDURES TO THE CABIN HEATER. FAIL-
URE TO FOLLOW THESE INSTRUCTIONS MAY
RESULT IN PERSONAL INJURY OR DEATH.
(1) Position the cabin heater fuel line to the vehi-
cle and connect the body retaining clips.
(2) Connect the heater fuel line to the fuel tank.
(3) Install the clamp that secure the heater fuel
line to the fuel tank. Tighten the clamp securely.
(4) Connect the heater fuel hose to the dosing
pump and the heater fuel line.
(5) Install the clamps that secure the heater fuel
hose to the dosing pump and the heater fuel line.
Tighten the clamps securely.
(6) Lower the vehicle.
