Owners of 2010-2014 Chevy Camaros may comment about a popping noise (intermittent or multiple) from the rear of the vehicle after a cold start (this may also occur during an EVAP purge event).

The cause is the auxiliary fuel module in the left side of the fuel tank changing height (spring loaded leg) as the fuel tank slightly collapses.

Replace the auxiliary fuel module/sender with a newly designed part, P/N 13592089.
