Here's why:
* Slight variations: Even within the same model year, there might be minor variations in fuel pump specifications based on engine type (e.g., 4-cylinder vs. V6), transmission type (automatic vs. manual), and even options packages.
* Electrical connectors: The electrical connector on the fuel pump may be slightly different.
* Fuel pressure: The fuel pressure specifications could be slightly different, potentially leading to performance issues or even damage.
Before swapping: It's crucial to check the part numbers on the fuel pumps to ensure they're identical or cross-referenced as compatible. A parts store (online or brick-and-mortar) can be helpful in this regard. Using a different fuel pump could lead to problems down the line. Using a reliable parts store's online database will allow you to find the correct fuel pump based on your specific VIN.
