Fuel Tank - Dodge Dakota Sport 2001 Service Manual

14 - 18 FUEL DELIVERY
FUEL RAIL (Continued)
CAUTION: The left and right fuel rails are replaced
as an assembly. Do not attempt to separate rail
halves at connecting hose (Fig. 21). Due to the
design of this connecting hose, it does not use any
clamps. Never attempt to install a clamping device
of any kind to hose. When removing fuel rail
assembly for any reason, be careful not to bend or
kink connecting hose.
(1) Apply a small amount of clean engine oil to
each fuel injector o-ring. This will help in fuel rail
installation.
(2) Install injector(s) and injector clip(s) to fuel rail.
(3) Position fuel rail/fuel injector assembly to injec-
tor openings on intake manifold.
(4) Guide each injector into intake manifold. Be
careful not to tear injector o-ring.
(5) Push right fuel rail down until fuel injectors
have bottomed on injector shoulder. Push left fuel
rail down until fuel injectors have bottomed on injec-
tor shoulder.
(6) Install fuel rail mounting bolts.
(7) Connect electrical connector to intake manifold
air temperature sensor.
(8) Connect electrical connectors at all fuel injec-
tors. To install connector, refer to (Fig. 23). Push con-
nector onto injector (1) and then push and lock red
colored slider (2). Verify connector is locked to injec-
tor by lightly tugging on connector.
(9) Install A/C support bracket (if equipped).
(10) Install throttle body to intake manifold. Refer
to Throttle Body installation in this group.
(11) Install fuel tube (line) at side of fuel rail.
Refer to Quick-Connect Fittings for procedures.
(12) Install air cleaner.
(13) Connect battery cable to battery.
(14) Start engine and check for leaks.
INSTALLATION - 4.7L
(1) If fuel injectors are to be installed, refer to Fuel
Injector Removal/Installation.
(2) Apply a small amount of engine oil to each fuel
injector o-ring. This will help in fuel rail installation.
(3) Position fuel rail/fuel injector assembly to
machined injector openings in cylinder head.
(4) Guide each injector into cylinder head. Be care-
ful not to tear injector o-rings.
(5) Push right side of fuel rail down until fuel
injectors have bottomed on cylinder head shoulder.
Push left fuel rail down until injectors have bot-
tomed on cylinder head shoulder.
(6) Install 4 fuel rail mounting bolts and tighten to
27 N·m (20 ft. lbs.).
(7) Install ignition coils. Refer to Ignition Coil
Removal/Installation.
(8) Connect electrical connectors to throttle body.
(9) Connect electrical connectors to MAP and IAT
sensors.
(10) Connect electrical connectors at all fuel injec-
tors. To install connector, refer to (Fig. 27). Push con-
nector onto injector (1) and then push and lock red
colored slider (2). Verify connector is locked to injec-
tor by lightly tugging on connector.
(11) Connect vacuum lines to throttle body.
(12) Connect fuel line latch clip and fuel line to
fuel rail. Refer to Quick-Connect Fittings.
(13) Connect wiring to rear of generator.
(14) Install air box to throttle body.
(15) Install air duct to air box.
(16) Connect battery cable to battery.
(17) Start engine and check for leaks.

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.
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 connections.
A rollover valve(s) is mounted into the top of the
fuel tank (or pump module). Refer to Rollover Valve
information.
An evaporation control system is connected to the
rollover valve(s) to reduce emissions of fuel vapors
into the atmosphere. When fuel evaporates 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. Certain models are also
equipped with a self-diagnosing system using a Leak
Detection Pump (LDP). Refer to Emission Control
System for additional information.
REMOVAL
WARNING: THE FUEL SYSTEM IS UNDER A CON-
STANT PRESSURE (EVEN WITH ENGINE OFF).
BEFORE DRAINING FUEL TANK, FUEL SYSTEM
PRESSURE MUST BE RELEASED.
The fuel tank cannot be drained through the fill
or vent fittings at the top of the fuel tank. Two dif-
ferent procedures may be used to drain fuel tank
(using an approved gasoline draining station, or
using the DRB scan tool along with an approved gas-
oline draining station). Draining is done from the dis-
connected fuel line, at the fuel rail, with either
procedure.
