1999 DODGE RAM fuel pump

regulator on fuel pump module using proper procedure for fuel line
disconnect fitting. See FUEL LINE DISCONNECT FITTINGS. Fuel pump
module is located on top of fuel tank. See Fig. 27. Disconnect
electrical connector at fuel pump module. Disconnect vapor line from
rollover valve on top of fuel tank.
8) Lower fuel tank from vehicle. If necessary to drain fuel
tank or to remove fuel tank filler tube assembly from fuel tank, go to
next step.
9) Ensure area around disconnect fitting at fuel tank for

fitting is fully pressed onto fuel tank fitting before attempting to
push release sleeve into disconnect fitting.
11) Push release sleeve upward into disconnect fitting as far
as possible to release the retaining tabs in disconnect fitting. See
Fig. 37 . Ensure release sleeve is pushed evenly into disconnect
fitting. Pull small vent tube with disconnect fitting from fuel tank.
Drain remaining fuel from fuel tank into an approved gasoline
container if necessary.
12) If necessary to remove large fill tube from fuel tank,
push disconnect fitting on end of large fill tube toward fitting fuel
tank as far as possible. See Fig. 37. Ensure disconnect fitting is
fully pressed onto fuel tank fitting before attempting to push release
sleeve into disconnect fitting.
13) Push release sleeve upward into disconnect fitting as far
as possible to release the retaining tabs in disconnect fitting. See
Fig. 37 . Ensure release sleeve is pushed evenly into disconnect
fitting. Pull large fill tube with disconnect fitting from fuel tank.

Installation

1) To install, reverse removal procedure. If installing small
vent tube and large fill tube on fuel tank, ensure fuel tank fittings
are clean.
2) Install disconnect fitting on fuel tank fitting until
disconnect fitting snaps onto fuel tank fitting. Pull on small vent
tube or and large fill tube to ensure disconnect fitting is locked on
fuel tank fitting. To verify proper installation of disconnect
fitting, ensure the distance between release sleeve and top of fuel
tank fitting is .50" (12.7 mm) on small vent tube or .25" (6.4 mm) o\
n
large fill tube. See Fig. 37.
3) Install fuel lines on fuel filter/fuel pressure regulator
on fuel pump module using proper procedure. See FUEL LINE DISCONNECT
FITTINGS under FUEL SYSTEM.
CAUTION: DO NOT overtighten fuel tank strap retaining nuts during
installation.
4) Tighten fuel tank strap retaining nuts to specification.
See TORQUE SPECIFICATIONS. To install remaining components, reverse
removal procedure. Start engine and check for fuel leaks.
Removal (Durango)
1) Fuel tank may be drained by removing vent hose from rear
of fuel tank, or by pumping fuel from fuel tank using the fuel pump if
fuel pump is operating. If removing vent hose from fuel tank to drain
the fuel, go to step 4). If using fuel pump to drain the fuel tank, go
to next step.
2) Disconnect fuel line from fuel rail. See FUEL LINE AT FUEL
RAIL under FUEL SYSTEM. Connect Fuel Hose (6541, 6539, 6631 or 6923)
for proper engine application at fuel line fitting on fuel rail. Place
remaining end of fuel hose in an approved gasoline container.
3) Connect scan tool to Data Link Connector (DLC). DLC is a
16-pin connector attached to bottom of driver's side of the instrument
panel, just to the right of the brake pedal. Using scan tool
manufacturer's instructions, activate the fuel pump and pump fuel from
fuel tank. Once fuel tank is empty, remove scan tool. Reinstall fuel
line on fuel rail using proper procedure. Go to step 5).
4) Release fuel pressure from fuel system. See FUEL SYSTEM
PRESSURE RELEASE. Ensure negative battery cable is disconnected.
Remove fuel tank cap to release any residual fuel tank pressure.
5) Raise and support vehicle. Remove necessary skid plates
for access to fuel tank. Disconnect vent and filler hose from rear of
fuel tank. If fuel tank was not previously drained, place drain hose
in vent hose fitting at rear of fuel tank. Drain fuel from fuel tank
into an approved gasoline container.
6) Support fuel tank with transmission jack. Remove fuel tank
strap retaining nuts. Position fuel tank straps toward outside of
vehicle. Slightly lower fuel tank. Ensure rear of fuel tank is higher
than front of fuel tank to prevent any spilling any remaining fuel in
fuel tank.
7) Disconnect fuel line from fuel filter/fuel pressure
regulator on fuel pump module using proper procedure for fuel line
disconnect fitting. See FUEL LINE DISCONNECT FITTINGS. Fuel pump
module is located on top of fuel tank. See Fig. 28. Disconnect
electrical connector at fuel pump module. Disconnect vapor line from
rollover valves on top of fuel tank and EVAP line from fuel pump
module. Lower fuel tank from vehicle.
CAUTION: DO NOT overtighten fuel tank strap retaining nuts during
installation.
Installation
1) To install, reverse removal procedure. Install fuel lines

on fuel filter/fuel pressure regulator on fuel pump module using
proper procedure. See FUEL LINE DISCONNECT FITTINGS.
