Condition
Some customers may comment on an inaccurate fuel level gauge reading. In a small number of cases, the vehicle ran out of fuel when the gauge still
indicated 1/8 tank.
Cause
The cause of this condition may be insufficient fuel transfer from the left fuel reservoir to the right fuel reservoir. The poor fuel transfer may be the result
of one or a combination of both of the following:
^
The sender fuel feed (transfer) pipe has two anti-siphon holes in the middle of the pipe which are too large.
^
A clogged/restricted transfer (jet) pump - part of the RH primary fuel tank module.
Diagnosis
Important:
DO NOT replace the instrument panel cluster (IPC) or the engine control module (ECM) unless diagnosis has determined them to be at fault.
Follow published diagnostics for any stored diagnostic trouble codes (DTC) or use the diagnosis information for fuel gauge inaccuracy (SI Document). If
the diagnosis leads you inside the fuel tank, determine if the vehicle came in an as-failed condition; pay particular attention to the quantity of fuel in the
left and right reservoirs as the tank is lowered from the vehicle. Fuel remaining in the left reservoir and no fuel in the right reservoir is a good indication
of poor fuel transfer. If the vehicle is not in a failed condition, it may be necessary to run the vehicle out of fuel to duplicate the concern.
Correction
Replace the sender fuel feed (transfer) pipe with P/N 10388380. This new pipe has one anti-siphon hole. Also, inspect the RH primary fuel tank module
for a clogged/restricted transfer (jet) pump. Use the procedure listed below:
1.
Remove the RH primary fuel tank module from the fuel tank. Refer to the Primary Fuel Tank Module Replacement procedure in the Engine
Controls sub-section of the Service Manual.
2.
Disconnect the electrical connector from the LH secondary fuel tank module.
