The typical price range for a 2008 Cadillac CTS fuel pump module is about $120 to $420 for the part, with installed costs commonly ranging from $400 to $900 depending on whether you choose aftermarket or OEM parts and the labor rate in your area.
In this article, we break down the factors that affect price, compare aftermarket versus OEM options, and outline what you can expect to pay for labor and installation, plus tips for getting the best value and ensuring compatibility with your CTS's engine configuration.
Part price ranges
Prices vary by source, but the following ranges reflect typical listings from major auto parts retailers and GM-equivalent suppliers for the 2008 CTS in-tank fuel pump module.
- Aftermarket fuel pump module: typically $120–$220.
- OEM/GM-branded fuel pump module: typically $240–$420.
Conclusion: The biggest variable is the choice between aftermarket and OEM; both can fit the CTS when matched to the correct engine and tank configuration, but OEM parts tend to come with stronger warranty support.
Labor and total installed cost
Because the fuel pump is inside the fuel tank, replacement is a labor-intensive job that usually requires tank access. Labor rates and time vary by region and shop.
- Labor time and cost: typically 2–4 hours at $80–$150 per hour, roughly $160–$600 in labor charges.
- Installed total: commonly about $400–$900 in many U.S. markets, with higher costs in metropolitan areas or if additional work is needed (e.g., tank strap replacement, corrosion issues, or fuel line work).
Conclusion: Expect a substantial portion of the price to be labor; always get written estimates from several shops and ask whether diagnostic charges are included or waived with the pump replacement.
Shopping and warranty considerations
OEM vs aftermarket nuances
OEM pumps are designed to GM specifications and often carry a longer warranty, but price more; aftermarket options are typically cheaper and widely available but check warranty terms and compatibility notes with your CTS variant.
What to verify before purchase
Verify the part number correctly matches your CTS' engine and fuel tank configuration, confirm that the kit includes the pump, sending unit, seal, and any required gaskets, and check whether the vendor offers a warranty or return policy.
Summary: For a 2008 Cadillac CTS, plan on roughly $120–$420 for the fuel pump module itself and about $160–$600 for labor, yielding a typical installed range of $400–$900. Always compare several shops and parts sources, confirm compatibility with your car’s configuration, and consider OEM versus aftermarket options to balance cost and warranty.
