How much does it cost to replace a fuel pump on a Lexus is350?
For a Lexus IS350, replacing the fuel pump typically costs between roughly $600 and $1,700, depending on the year, labor rates, and whether you choose an OEM or aftermarket pump. This range includes parts, labor, and common ancillary charges.
In this article, we break down the typical price range, explain the main factors that influence price, and offer guidance on how to compare quotes from repair shops across model years of the IS350.
Cost overview
What you pay breaks down into parts, labor, and possible extras. The IS350's fuel pump is in-tank and replacement often involves removing the fuel tank, which drives up both time and cost.
- Parts: OEM fuel pump module typically in the range of $350–$650; aftermarket pumps commonly $150–$350.
- Labor: 2–5 hours of work is typical, with independent shops charging roughly $90–$150 per hour and dealers often $150–$200 per hour. Total labor could be about $180–$600 at an independent shop or $300–$1,000 at a dealership.
- Additional costs: diagnostic fees if needed, sending unit or fuel filter replacements, gaskets/o-rings, tax, and disposal fees.
Total price can vary widely by shop and year; commonly, expect roughly $600–$1,700 at independent shops and $1,000–$2,000+ at a dealership, depending on parts choice and local rates.
What affects the price
Several factors influence the final bill for a fuel pump replacement on an IS350. Understanding these can help you compare quotes more accurately.
- Model year and generation, which can affect the accessibility of the pump and the complexity of the job.
- OEM versus aftermarket parts; OEM parts tend to cost more but may come with a longer or more comprehensive warranty.
- Labor rates by location and shop type (dealer vs. independent).
- Whether additional items need replacement (sending unit, fuel filter, O-rings) during the same service.
- Whether the fuel tank must be dropped or other extensive disassembly is required.
- Any recalls or service bulletins that impact the replacement procedure or required parts.
These factors explain why quotes can differ significantly across shops and regions. Always request an itemized estimate to understand what you're paying for.
Model-year considerations
Older IS350 models (roughly 2006–2013)
In older IS350s, the pump replacement often requires more labor time due to tank access or related components, which can push up both the parts and labor costs.
Newer IS350 models (roughly 2014–2020+)
Newer model years may use a slightly different pump-and-sending-unit design. While access can be somewhat similar, price variations often come from dealer vs. aftermarket parts and from current labor rates.
DIY vs. professional service
Replacing a fuel pump is a complex, safety-sensitive job that involves the fuel system and potential fuel vapor exposure. It is generally recommended to have a trained technician perform the work, especially for modern cars with integrated modules and complex tank configurations.
Safety and warranty considerations
Working with the fuel system carries fire and inhalation risks. If your car is under factory warranty or a current service bulletin, a dealer may provide the most reliable guidance and coverage. Pump modules often come with limited warranties; confirm the duration with the seller and ensure proper installation procedures are followed to preserve warranty coverage.
What to ask your shop
Before committing, use these questions to get a clear, itemized understanding of the price and scope of work.
- Is the quoted price for OEM or aftermarket fuel pump modules?
- Does the estimate include the fuel sending unit and any associated components (filters, gaskets, O-rings)?
- What is the labor rate, and how many hours are estimated for the job?
- Is there a diagnostic fee, core charge, or disposal fee included? Are there additional charges for tank dropping?
- What warranty is offered on parts and labor, and for how long?
Getting an itemized quote helps you compare options and avoid surprises when the final bill arrives.
Summary
Replacing the fuel pump on a Lexus IS350 is a capable but costly repair due to the in-tank location and labor intensity. Plan for roughly $600–$1,700 at independent shops and potentially $1,000–$2,000+ at a dealership, depending on the model year, part choice, and local labor rates. By understanding the main cost drivers and obtaining detailed quotes, you can navigate the process more confidently and choose the option that best fits your needs.
Bottom line
If you’re experiencing symptoms like the car failing to start, stalling, or inconsistent fuel pressure, a fuel pump failure could be the culprit. Contact multiple reputable shops for quotes, ask about part types and warranties, and ensure the technician provides an itemized breakdown before you authorize the work.
