SUBJECT:
FUEL SENDER WHISTLING NOISE


MODELS AFFECTED:
1988 REGALS
1989 REGALS PRODUCED PRIOR TO VIN K1405635


Some 1988-89 Regals assembled prior to the VIN breakpoint, indicated above, may exhibit a whistling noise coming from the rear of the vehicle when the tank pressure control valve is venting to the carbon canister.

This noise condition is most apparent from outside the vehicle with the engine shut off after operation at higher ambient temperatures.

In diagnosing this condition, if the noise is eliminated by removal of the fuel tank filler cap, the vehicle may be repaired by installation of fuel tank sender, Part Number 25026737, and vapor carbon canister, Part Number 17089089, following applicable shop manual procedures.

Parts are currently available from GMSPO.
