RAIL - FUEL
DESCRIPTION
The fuel injector rail is used to mount the fuel injectors to the engine.
OPERATION
High pressure from the fuel pump is routed to the fuel rail. The fuel rail then supplies the necessary fuel to each
individual fuel injector.
A quick-connect fitting with a safety latch clip is used to attach the fuel linetothefuelrail.
The fuel rail is not repairable.
CAUTION: The left and right sections of the fuel rail are connected with either a flexible connecting hose, or
joints. Do not attempt to separate the rail halves at these connecting hoseor joints. Due to the design of
the connecting hose or joint, it does not use any clamps. Never attempt to install a clamping device of any
kind to the hose or joint. When removing the fuel rail assembly for any reason, be careful not to bend or
kink the connecting hose or joint.
REMOVAL
3.7L V-6
WARNING: The fuel system is under constant pressure even with engine off. Before servicing fuel rail, fuel
system pressure must be released.
CAUTION: The left and right fuel rails are replaced as an assembly. Do not attempt to separate rail halves
at connector tubes. Due to design of tubes, it does not use any clamps. Neverattempt to install a clamping
device of any kind to tubes. When removing fuel rail assembly for any reason, be careful not to bend or
kink tubes.
1. Remove fuel tank filler tube cap.
2. Perform Fuel System Pressure Release Procedure.
(Refer to 14 - FUEL SYSTEM/FUEL DELIVERY -
STANDARD PROCEDURE)
3. Remove negative battery cable at battery.
4. Remove air duct at throttle body air box.
5. Remove air box at throttle body.
6. Remove air resonator mounting bracket at front of
throttle body (2 bolts).
7. Disconnect fuel line latch clip and fuel line at fuel
rail. A special tool will be necessary for fuel line
disconnection. (Refer to 14 - FUEL SYSTEM/FUEL
DELIVERY/QUICK CONNECT FITTING - STAN-
DARD PROCEDURE)
8. Remove necessary vacuumlines at throttle body.
9. Disconnect electrical connectors at all 6 fuel injec-
tors. To remove connector refer to. Push red col-
ored slider away from injector (1). While pushing
slider, depress tab (2) and remove connector (3)
from injector. The factory fuel injection wiring har-
ness is numerically tagged (INJ 1, INJ 2, etc.) for
injector position identification. If harness is not
tagged, note wiring location before removal.
10. Disconnect electrical connectors at all throttle body sensors.
