PRODUCT EMISSION RECALL
SUBJECT:

Fuel Fill Pipe Anti-siphon Grid Out of Position

MODELS:

2014 Chevrolet Corvette

CONDITION
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2014
model year Chevrolet Corvette model vehicles. These vehicles may have been built with an outof-position “anti-siphon” grid within the fuel fill pipe. As a result, the grid may move over time and
become located from slightly deeper in the fuel fill pipe to totally dislodged from the pipe and
move to the bottom of the fuel tank.
CORRECTION
Dealers are to replace the fuel tank fill pipe, and if necessary, inspect the fuel tank for the
dislodged anti-siphon grid. This service will be performed for you at no charge.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel
should always check this site to confirm vehicle involvement prior to beginning any required
inspections and/or repairs. It is important to routinely use this tool to verify eligibility because
not all similar vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete
vehicle identification number, customer name, and address information has been prepared and
will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or
sent directly to export dealers. Dealers will not have a report available if they have no involved
vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle
Registration Records. The use of such motor vehicle registration data for any purpose other
than follow-up necessary to complete this recall is a violation of law in several
states/provinces/countries. Accordingly, you are urged to limit the use of this report to the followup necessary to complete this recall.

SERVICE PROCEDURE
This procedure covers replacement of the fuel filler pipe and inspection for the presence and
location of the fuel filler pipe vapor grid. It may be necessary to retrieve the grid if it has
become dislodged from the fill pipe. The service fuel tank filler pipe comes as an assembly. It
will be necessary to remove the rubber hose from the service part. This will allow the original
hose to remain in the vehicle avoiding the need to remove the fuel tank.

CUSTOMER NOTIFICATION
General Motors will notify customers of this recall on their vehicle (see copy of customer letter
included with this bulletin).
In order to ensure full protection under the emission warranty, and the right to participate in future
recalls, the customer notification letter recommends that customers have their vehicles serviced
as soon as possible. It also advises that failure to do so could legally be determined to be lack
of proper maintenance. The vehicle may fail a state or local emission inspection test if the recall
work is not completed.
DEALER RECALL RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this recall must be held and
inspected/repaired per the service procedure of this recall bulletin before customers take
possession of these vehicles.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of
mileage, age of vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which
there is no customer information indicated on the dealer listing, are to be contacted by the dealer.
Arrangements are to be made to make the required correction according to the instructions
contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in
contacting customers. Recall follow-up cards should not be used for this purpose, since the
customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your
dealership for service in the future, you must take the steps necessary to be sure the recall
correction has been made before selling or releasing the vehicle.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA ***
When a California emissions recall is completed by a GM dealer, the dealer must provide the
vehicle owner a “Proof of Correction Certificate” which the owner may need to present to the
California Department Of Motor Vehicles (DMV) when renewing their vehicle registration.
Without this correction certificate, the owner may be unable to renew their vehicle registration.
Additional Certificates can be obtained, at no charge, from Dealer Support Materials by ordering
on the web from the DWD Store, www.gmdealerworld.com, and then click on the DWD Store
link; request GM Item Number 1825 when ordering.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.

This notice applies to your vehicle, VIN: ___________________________________________
Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a voluntary emission recall
that includes your vehicle.
Reason For This Recall: Your Chevrolet Corvette may have been built with an out-of-position
“anti-siphon” grid within the fuel fill pipe. As a result, the grid may move over time and become
located from slightly deeper in the fuel fill pipe to totally dislodged from the pipe and move to
the bottom of the fuel tank.
What Will Be Done: Your GM dealer will replace the fuel tank fill pipe, and if necessary,
inspect the fuel tank for the dislodged anti-siphon grid. This service will be performed for you at
no charge.
How Long Will The Repair Take? Because of service scheduling requirements, it is likely
that your dealer will need your vehicle longer than the actual service correction time of
approximately 45 minutes.
What You Should Do: Please contact your GM dealer as soon as possible to arrange a
service date and to assure parts availability. Instructions for making this correction have been
sent to your dealer. Please ask your dealer if you wish to know how much time will be needed
to schedule, process, and repair your vehicle.
If you have any questions or need any assistance, just contact your dealer or the appropriate
Customer Assistance Center at the number listed below.

Emission Law Information: In order to ensure your full protection under the emission
warranty made applicable to your vehicle by state and federal law, and your right to participate

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed
prior to California registration renewal. Uncorrected emission recalls will result in the inability
to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of
Correction Certificate". Keep this certificate and, if required, present it to the Department of
Motor Vehicles when renewing your California registration as proof of recall completion.
We are sorry to cause you this inconvenience; however, we have taken this action in the
interest of your continued satisfaction with our products.
