The customer is solely responsible for determining correct fitment based on the vehicle’s VIN (Vehicle Identification Number).
GM truck and SUV platforms often utilize up to five or more different fuel module configurations for the same model year. Searching by vehicle type and trim level is insufficient; the VIN is the ultimate "Go / No-Go" check for fitment.
How to Verify Fitment:
- Find your 17-digit VIN (found on your dashboard or door jamb).
- Visit GM Parts Giant or GM Parts Direct and enter your **VIN** to find your exact **OEM Part Number**.
- Cross-reference that OEM number on the Delphi Parts Catalog to find the Delphi **Interchange Number**.
- Verify that the Delphi number or the GM OEM number matches our **Interchange List** above.
If you are unsure of the results, please reach out to Racetronix support with your VIN before placing your order.
