on fuel filter/fuel pressure regulator on fuel pump module using
proper procedure. See FUEL LINE DISCONNECT FITTINGS.
2) Tighten fuel tank strap retaining nuts to specification.
See TORQUE SPECIFICATIONS. Start engine and check for fuel leaks.
Removal (Ram Pickup)
1) Fuel tank may be drained by lowering fuel tank, or by
pumping fuel from fuel tank using the fuel pump if fuel pump is
operating. If lowering 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. 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 straight above the accelerator 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. Open fuel tank filler door.
Remove fuel tank filler tube assembly-to-body screws. Support fuel
tank with transmission jack. Remove fuel tank strap retaining nuts.
6) Slightly lower fuel tank. If fuel tank was not previously
drained, slightly rotate fuel tank so vent hose and filler hose on
fuel tank are above the fuel level in the fuel tank to prevent fuel
leakage when hoses are disconnected. Vent hose and filler hose attach
to fitting on the fuel tank. See Fig. 29.
7) Disconnect vent hose from vent hose fitting on fuel tank.
If fuel tank was previously drained, go to next step. If fuel tank was
not previously drained, place drain hose in vent hose fitting on fuel
tank. Drain fuel from fuel tank into an approved gasoline container.
Go to next step.
8) Disconnect filler hose from filler hose fitting on fuel
tank. Disconnect electrical connector at fuel pump module. Fuel pump
module is located on top of fuel tank. See Fig. 29.
9) 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 under FUEL
SYSTEM.
10) Disconnect necessary vapor hoses from rollover valves on
top of fuel tank or fuel pump module. See Fig. 29. 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.
2) Tighten fuel tank strap retaining nuts to specification.
See TORQUE SPECIFICATIONS. Start engine and check for fuel leaks.
Removal (Ram Van & Ram Wagon)
1) Fuel tank may be drained by siphoning fuel out through
small vent hose on fuel and vent hose fitting assembly on fuel tank,
or by pumping fuel from fuel tank using the fuel pump if fuel pump is
operating. If siphoning fuel out through small vent hose on fuel and
vent hose fitting assembly on fuel tank, go to step 4). If using fuel
