Bulletin No.: PIP5122F Published date: 03/2/2018 Preliminary Information PIP5122F Pop Noise From Fuel Tank After a Cold Start or EVAP Purge Event Models Brand: Model: VIN: Model Years: from Engine: to Transmissions: Chevrolet Equinox 2010 - 2017 All All All All GMC Terrain 2010 - 2017 All All All All Supersession Statement This PI was superseded to update Parts Information. Please discard PIP5122E. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition / Concern Intermittently customers may comment about a pop or multiple popping noise from the rear of the vehicle shortly after a cold start or EVAP purge event. Recommendations / Instructions The technician should be able to duplicate the concern by commanding a purge and seal on the EVAP system using GDS2. As the vacuum reaches 3 to 5 inches, the pop/popping noise should be duplicated. The cause for this concern is the auxiliary fuel pump in the left side of the fuel tank changing height (spring loaded leg). Important: The condition described in this PI applies only to the auxiliary fuel pump module assembly. The Parts Catalog calls this auxiliary pump component (1) the "Fuel Pump Auxiliary" which is the correct part for this repair. Replacing the primary fuel pump module (2) assembly would NOT correct this noise condition. The parts catalog calls this primary pump component the "Fuel Pump" which is the incorrect part for this repair.
